-===
-
-功能强大的流式文本编辑器
-
-## 补充说明
-
-**sed** 是一种流编辑器，它是文本处理中非常中的工具，能够完美的配合正则表达式使用，功能不同凡响。处理时，把当前处理的行存储在临时缓冲区中，称为“模式空间”（pattern space），接着用sed命令处理缓冲区中的内容，处理完成后，把缓冲区的内容送往屏幕。接着处理下一行，这样不断重复，直到文件末尾。文件内容并没有 改变，除非你使用重定向存储输出。Sed主要用来自动编辑一个或多个文件；简化对文件的反复操作；编写转换程序等。
-
-## sed的选项、命令、替换标记  
-
- **命令格式** 
-
-```
-sed [options] 'command' file(s)
-sed [options] -f scriptfile file(s)
-```
-
-### 选项  
-
-```
--e<script>或--expression=<script>：以选项中的指定的script来处理输入的文本文件；
--f<script文件>或--file=<script文件>：以选项中指定的script文件来处理输入的文本文件；
--h或--help：显示帮助；
--n或--quiet或——silent：仅显示script处理后的结果；
--V或--version：显示版本信息。
-```
-
-### 参数  
-
-文件：指定待处理的文本文件列表。
-
-### sed命令  
-
-```
- **a\**  在当前行下面插入文本。
- **i\**  在当前行上面插入文本。
- **c\**  把选定的行改为新的文本。
- **d**  删除，删除选择的行。
- **D**  删除模板块的第一行。

-```
-
-## sed用法实例  
-
-### 替换操作：s命令  
-
-替换文本中的字符串：
-
-```
-sed 's/book/books/' file
-```
-
- **-n选项** 和 **p命令** 一起使用表示只打印那些发生替换的行：
-
-sed -n 's/test/TEST/p' file
-
-直接编辑文件 **选项-i** ，会匹配file文件中每一行的第一个book替换为books：
-
-```
-sed -i 's/book/books/g' file
-```
-
-### 全面替换标记g  
-
-使用后缀 /g 标记会替换每一行中的所有匹配：
-
-```
-sed 's/book/books/g' file
-```
-
-当需要从第N处匹配开始替换时，可以使用 /Ng：
-
-```
-echo sksksksksksk | sed 's/sk/SK/2g'
-skSKSKSKSKSK
-
-echo sksksksksksk | sed 's/sk/SK/3g'
-skskSKSKSKSK
-
-echo sksksksksksk | sed 's/sk/SK/4g'
-skskskSKSKSK
-```
-
-### 定界符  
-
-以上命令中字符 / 在sed中作为定界符使用，也可以使用任意的定界符：
-
-```
-sed 's:test:TEXT:g'
-sed 's|test|TEXT|g'
-```
-
-定界符出现在样式内部时，需要进行转义：
-
-```
-sed 's/\/bin/\/usr\/local\/bin/g'
-```
-
-### 删除操作：d命令  
-
-删除空白行：
-
-```
-sed '/^$/d' file
-```
-
-删除文件的第2行：
-
-```
-sed '2d' file
-```
-
-删除文件的第2行到末尾所有行：
-
-```
-sed '2,$d' file
-```
-
-删除文件最后一行：
-
-```
-sed '$d' file
-```
-
-删除文件中所有开头是test的行：
-
-```
-sed '/^test/'d file
-```
-
-### 已匹配字符串标记&  
-
-正则表达式 \w\+ 匹配每一个单词，使用 [&] 替换它，& 对应于之前所匹配到的单词：
-
-```
-echo this is a test line | sed 's/\w\+/[&]/g'
-[this] [is] [a] [test] [line]
-```
-
-所有以192.168.0.1开头的行都会被替换成它自已加localhost：
-
-```
-sed 's/^192.168.0.1/&localhost/' file
-192.168.0.1localhost
-```
-
-### 子串匹配标记\1  
-
-匹配给定样式的其中一部分：
-
-```
-echo this is digit 7 in a number | sed 's/digit \([0-9]\)/\1/'
-this is 7 in a number
-```
-
-命令中 digit 7，被替换成了 7。样式匹配到的子串是 7，\(..\) 用于匹配子串，对于匹配到的第一个子串就标记为  **\1** ，依此类推匹配到的第二个结果就是  **\2** ，例如：
-
-```
-echo aaa BBB | sed 's/\([a-z]\+\) \([A-Z]\+\)/\2 \1/'
-BBB aaa
-```
-
-love被标记为1，所有loveable会被替换成lovers，并打印出来：
-
-```
-sed -n 's/\(love\)able/\1rs/p' file
-```
-
-### 组合多个表达式  
-
-```
-sed '表达式' | sed '表达式'
-
-等价于：
-
-sed '表达式; 表达式'
-```
-
-### 引用  
-
-sed表达式可以使用单引号来引用，但是如果表达式内部包含变量字符串，就需要使用双引号。
-
-```
-test=hello
-echo hello WORLD | sed "s/$test/HELLO"
-HELLO WORLD
-```
-
-### 选定行的范围：,（逗号）  
-
-所有在模板test和check所确定的范围内的行都被打印：
-
-```
-sed -n '/test/,/check/p' file
-```
-
-打印从第5行开始到第一个包含以test开始的行之间的所有行：
-
-```
-sed -n '5,/^test/p' file
-```
-
-对于模板test和west之间的行，每行的末尾用字符串aaa bbb替换：
-
-```
-sed '/test/,/west/s/$/aaa bbb/' file
-```
-
-### 多点编辑：e命令  
-
--e选项允许在同一行里执行多条命令：
-
-```
-sed -e '1,5d' -e 's/test/check/' file
-```
-
-上面sed表达式的第一条命令删除1至5行，第二条命令用check替换test。命令的执行顺序对结果有影响。如果两个命令都是替换命令，那么第一个替换命令将影响第二个替换命令的结果。
-
-和 -e 等价的命令是 --expression：
-
-```
-sed --expression='s/test/check/' --expression='/love/d' file
-```
-
-### 从文件读入：r命令  
-
-file里的内容被读进来，显示在与test匹配的行后面，如果匹配多行，则file的内容将显示在所有匹配行的下面：
-
-```
-sed '/test/r file' filename
-```
-
-### 写入文件：w命令    
-
-在example中所有包含test的行都被写入file里：
-
-```
-sed -n '/test/w file' example
-```
-
-### 追加（行下）：a\命令  
-
-将 this is a test line 追加到 以test 开头的行后面：
-
-```
-sed '/^test/a\this is a test line' file
-```
-
-在 test.conf 文件第2行之后插入 this is a test line：
-
-```
-sed -i '2a\this is a test line' test.conf
-```
-
-### 插入（行上）：i\命令  
-
-将 this is a test line 追加到以test开头的行前面：
-
-```
-sed '/^test/i\this is a test line' file
-```
-
-在test.conf文件第5行之前插入this is a test line：
-
-```
-sed -i '5i\this is a test line' test.conf
-```
-
-### 下一个：n命令  
-
-如果test被匹配，则移动到匹配行的下一行，替换这一行的aa，变为bb，并打印该行，然后继续：
-
-```
-sed '/test/{ n; s/aa/bb/; }' file
-```
-
-### 变形：y命令  
-
-把1~10行内所有abcde转变为大写，注意，正则表达式元字符不能使用这个命令：
-
-```
-sed '1,10y/abcde/ABCDE/' file
-```
-
-### 退出：q命令  
-
-打印完第10行后，退出sed
-
-```
-sed '10q' file
-```
-
-### 保持和获取：h命令和G命令  
-
-在sed处理文件的时候，每一行都被保存在一个叫模式空间的临时缓冲区中，除非行被删除或者输出被取消，否则所有被处理的行都将 打印在屏幕上。接着模式空间被清空，并存入新的一行等待处理。
-
-```
-sed -e '/test/h' -e '$G' file
-```
-
-在这个例子里，匹配test的行被找到后，将存入模式空间，h命令将其复制并存入一个称为保持缓存区的特殊缓冲区内。第二条语句的意思是，当到达最后一行后，G命令取出保持缓冲区的行，然后把它放回模式空间中，且追加到现在已经存在于模式空间中的行的末尾。在这个例子中就是追加到最后一行。简单来说，任何包含test的行都被复制并追加到该文件的末尾。
-
-### 保持和互换：h命令和x命令  
-
-互换模式空间和保持缓冲区的内容。也就是把包含test与check的行互换：
-
-```
-sed -e '/test/h' -e '/check/x' file
-```
-
-### 脚本scriptfile  
-
-sed脚本是一个sed的命令清单，启动Sed时以-f选项引导脚本文件名。Sed对于脚本中输入的命令非常挑剔，在命令的末尾不能有任何空白或文本，如果在一行中有多个命令，要用分号分隔。以#开头的行为注释行，且不能跨行。
-
-```
-sed [options] -f scriptfile file(s)
-```
-
-### 打印奇数行或偶数行  
-
-方法1：
-
-```
-sed -n 'p;n' test.txt  #奇数行
-sed -n 'n;p' test.txt  #偶数行
-
-```
-
-方法2：
-
-```
-sed -n '1~2p' test.txt  #奇数行
-sed -n '2~2p' test.txt  #偶数行
-
-```
-
-### 打印匹配字符串的下一行  
-
-```
-grep -A 1 SCC URFILE
-sed -n '/SCC/{n;p}' URFILE
-awk '/SCC/{getline; print}' URFILE
-
-```

+sed
+===
+
+功能强大的流式文本编辑器
+
+## 补充说明
+
+**sed** 是一种流编辑器，它是文本处理中非常中的工具，能够完美的配合正则表达式使用，功能不同凡响。处理时，把当前处理的行存储在临时缓冲区中，称为“模式空间”（pattern space），接着用sed命令处理缓冲区中的内容，处理完成后，把缓冲区的内容送往屏幕。接着处理下一行，这样不断重复，直到文件末尾。文件内容并没有 改变，除非你使用重定向存储输出。Sed主要用来自动编辑一个或多个文件；简化对文件的反复操作；编写转换程序等。
+
+## sed的选项、命令、替换标记  
+
+ **命令格式** 
+
+```

-**xargs命令** 是给其他命令传递参数的一个过滤器，也是组合多个命令的一个工具。它擅长将标准输入数据转换成命令行参数，xargs能够处理管道或者stdin并将其转换成特定命令的命令参数。xargs也可以将单行或多行文本输入转换为其他格式，例如多行变单行，单行变多行。xargs的默认命令是echo，空格是默认定界符。这意味着通过管道传递给xargs的输入将会包含换行和空白，不过通过xargs的处理，换行和空白将被空格取代。xargs是构建单行命令的重要组件之一。

-显示和修改IP到MAC转换表
+
+arp 命令用于显示和修改 IP 到 MAC 转换表。ARP 是 Address Resolution Protocol，地址解析协议，是通过解析网络层地址来找寻数据链路层地址的一个网络协议包中极其重要的网络传输协议。而该命令可以显示和修改 arp 协议解析表中的缓冲数据。
 
 ## 补充说明
 
-**arp命令** 用于操作主机的arp缓冲区，它可以显示arp缓冲区中的所有条目、删除指定的条目或者添加静态的ip地址与MAC地址对应关系。

Subject: [PATCH 0030/1081] Update sed.md (#68)

correct error

------------
*
Matches a sequence of zero or more instances of matches for the preceding regular expression, which must be an ordinary character, a special character preceded by \, a ., a grouped regexp (see below), or a bracket expression. As a GNU extension, a postfixed regular expression can also be followed by *; for example, a** is equivalent to a*. POSIX 1003.1-2001 says that * stands for itself when it appears at the start of a regular expression or subexpression, but many nonGNU implementations do not support this and portable scripts should instead use \* in these contexts.

 注意：规则的次序非常关键，`谁的规则越严格，应该放的越靠前`，而检查规则的时候，是按照从上往下的方式进行检查的。
 
-#### 防火墙的策略
-
-防火墙策略一般分为两种，一种叫`通`策略，一种叫`堵`策略，通策略，默认门是关着的，必须要定义谁能进。堵策略则是，大门是洞开的，但是你必须有身份认证，否则不能进，`所以通，是要全通，而堵，则是要选择`。

 **控制端口 / 服务**
 
 可以通过两种方式控制端口的开放，一种是指定端口号另一种是指定服务名。虽然开放 http 服务就是开放了 80 端口，但是还是不能通过端口号来关闭，也就是说通过指定服务名开放的就要通过指定服务名关闭；通过指定端口号开放的就要通过指定端口号关闭。还有一个要注意的就是指定端口的时候一定要指定是什么协议，tcp 还是 udp。知道这个之后以后就不用每次先关防火墙了，可以让防火墙真正的生效。

+uuto
+===
+
+将文件传送到远端的UUCP主机。
+
+## 补充说明
+
+**uuto命令** 为script文件，它实际上会执行uucp，用来将文件传送到远端UUCP主机，并在完成工作后，以邮件通知远端主机上的用户。
+
+### 语法  
+
+```
+uuto [文件][目的]
+```
+
+
+### 例子
+
+将文件传送到远程 UUCP 主机 localhost 的 tmp 目录，在命令提示符中直接输入如下命令：
+
+```bash
+uuto./testfile localhost/tmp # 将文件传送到远程UUCP 主机localhost的tmp目录 
+```
+
+该命令通常没有输出。

 firewalld自身并不具备防火墙的功能，而是和iptables一样需要通过内核的netfilter来实现，也就是说firewalld和 iptables一样，他们的作用都是用于维护规则，而真正使用规则干活的是内核的netfilter，只不过firewalld和iptables的结 构以及使用方法不一样罢了。

 ### 命令别名永久生效
+
 直接在shell里设定的命令别名，在终端关闭或者系统重新启动后都会失效，如何才能永久有效呢？办法就是将别名的设置加入~/.bashrc文件，然后重新载入下文件就可以了。
-```bash
+
+```shell
 $ vim ~/.bashrc
 ```
 在文件最后面加入别名设置，如：alias rm=’rm -i’，保存后重新载入：
-```bash
+
+```shell
 $ source ~/.bashrc
 ```
+
 这样就可以永久保存命令的别名了。因为修改的是当前用户目录下的.bashrc文件，所以这样的方式只对当前用户有用。如果要对所有用户都有效，修改/etc目录下的bashrc文件就可以了。在CentOS7下，这个文件是/etc/bash.bashrc。此外在CentOS7下，细看~/.bashrc文件，会发有这样一段代码：
-```bash

 #### 一、 范例演示
 
 在使用和维护Linux系统过程中，我们常常希望根据自己的需要来定义一些命令，那么这样的操作是不是很难呢？其实不是，系统已经为我们设置好了相关的命令，下面小编就以CentOS6.4系统为例，为大家演示如何创建自己的命令。
 
 #### 二、 自定义命令简介
-    CentOS系统下的创建自定义命令其实比较简单，使用的命令就是alias，具体使用的方法就是 alias 自定义命令名=‘命令’。但是需要注意的是，在自定义之前需要查看自定义的命令名是否是系统已经使用的命令名，否则会冲突，另外一个就是定期清理不需要的自定义命令名。

 #### 三、 演示举例
+
 假定系统操作员希望进行如下操作：
+
 1.进入目录/root
 2.查看目录下文件
 3.切换回根目录
+
 通常这需要三条命令 cd /root；ls；cd / ，如果需要经常使用那么我们可以通过自定义命令的方式用一条命令完成全部操作。
-![](alias\01.png)
 
 #### 四、 操作过程
-	首先使用命令 type 自定义命令名 ，查看自定义命令名是否被系统占用。从图中可以看出test命令名已被系统占用，所以不能使用，而loo这个命令名经查询可以使用。
-![](alias\02.png)
 
-	使用命令alias创建自定义命令：alias loo='cd /root;ls;cd /' 。需要注意的是命令的使用格式，分号与分号之间是没有空格的。
-![](alias\03.png)
 
-	测试一下自定义命令，当输入命令 loo 时，发现系统依次完成了 cd /root、ls、cd / 三条命令，说明设置成功。同时也可直接使用命令 alias  查询系统中是否添加了loo这个自定义命令。

 ### 实例  
 
 使用apt-get命令的第一步就是引入必需的软件库，Debian的软件库也就是所有Debian软件包的集合，它们存在互联网上的一些公共站点上。把它们的地址加入，apt-get就能搜索到我们想要的软件。/etc/apt/sources.list是存放这些地址列表的配置文件，其格式如下：
 
-```
+```shell
 deb web或[ftp地址] [发行版名字] main/contrib/non-[free]
 ```
 
@@ -36,55 +36,55 @@ deb web或[ftp地址] [发行版名字] main/contrib/non-[free]
 
 在修改`/etc/apt/sources.list`或者`/etc/apt/preferences`之后运行该命令。此外您需要定期运行这一命令以确保您的软件包列表是最新的：
 
-```
+```shell
 apt-get update
 ```
 
 安装一个新软件包：
 
-```
+```shell
 apt-get install packagename
 ```
 
 卸载一个已安装的软件包（保留配置文件）：
 
-```
+```shell
 apt-get remove packagename
 ```
 
 卸载一个已安装的软件包（删除配置文件）：
 
-```
+```shell
 apt-get –purge remove packagename
 ```
 
 会把已装或已卸的软件都备份在硬盘上，所以如果需要空间的话，可以让这个命令来删除你已经删掉的软件：
 
-```
+```shell
 apt-get autoclean apt
 ```
 
 这个命令会把安装的软件的备份也删除，不过这样不会影响软件的使用的：
 
-```
+```shell
 apt-get clean
 ```
 
 更新所有已安装的软件包：
 
-```
+```shell
 apt-get upgrade
 ```
 
 将系统升级到新版本：
 
-```
+```shell
 apt-get dist-upgrade
 ```
 
 定期运行这个命令来清除那些已经卸载的软件包的.deb文件。通过这种方式，您可以释放大量的磁盘空间。如果您的需求十分迫切，可以使用`apt-get clean`以释放更多空间。这个命令会将已安装软件包裹的.deb文件一并删除。大多数情况下您不会再用到这些.debs文件，因此如果您为磁盘空间不足 而感到焦头烂额，这个办法也许值得一试：
 
-```
+```shell
 apt-get autoclean

 许多用了多年Linux的人可能也没有用过e2label命令。但是这个命令相当有效。在介绍它之前,我们先看看`/etc/fstab文`件：
 
-```
+```shell
 label=//ext3 defaults 1 1
 /dev/hda7 /usr ext3 defaults 1 1
 ```
 
 第二行的意思很容易懂，就是把`/dev/hda7` mount到`/usr`上。第一行没有指明分区，意思是把label(卷标)为/ 的分区mount到/上。这样写的好处在于即使如果把硬盘从主板上的ide0(hda) 换到ide2(hdc)上，系统仍然可以自动挂载正确的分区。通常Linux安装的时候已经自动指定了卷标。如果是手动增加的新分区，可以用下边的命令为 其指定卷标：

 这表示除了相应的容量的限制外，还对文件/目录的数量做了12800个的软限制和51200个的硬限制。在保存了新的配置后，该用户的磁盘使用就不能超过硬限制。如果用户试图超过这个限制，该操作将被取消，然后得到一个错误信息。但是，如果每个用户都要这么麻烦的设置的话，那这种重复的体力劳动实在有点令人不寒而栗，而且也太浪费时间了。幸好edquota还有个-p参数（prototype）可以对已有的用户设置进行拷贝。例如，我们想对Jack、Tom、Chen三个用户使用和lanf一样的限额配置，可以使用如下的命令：

 ### 实例  
 
 如果是普通用户执行passwd只能修改自己的密码。如果新建用户后，要为新用户创建密码，则用passwd用户名，注意要以root用户的权限来创建。
 
-```
-[root@localhost ~]# passwd linuxde    //更改或创建linuxde用户的密码；
+```shell
+[root@localhost ~]# passwd linuxde     # 更改或创建linuxde用户的密码；
 Changing password for user linuxde.
-New UNIX password:          //请输入新密码；
-Retype new UNIX password:   //再输入一次；
-passwd: all authentication tokens updated successfully. //成功；
+New UNIX password:           # 请输入新密码；
+Retype new UNIX password:    # 再输入一次；
+passwd: all authentication tokens updated successfully.  # 成功；
 ```
 
 普通用户如果想更改自己的密码，直接运行passwd即可，比如当前操作的用户是linuxde。
 
-```
+```shell
 [linuxde@localhost ~]$ passwd
-Changing password for user linuxde. //更改linuxde用户的密码；
-(current) UNIX password:   //请输入当前密码；
-New UNIX password:         //请输入新密码；
-Retype new UNIX password:  //确认新密码；
-passwd: all authentication tokens updated successfully. //更改成功；
+Changing password for user linuxde.  # 更改linuxde用户的密码；
+(current) UNIX password:    # 请输入当前密码；
+New UNIX password:          # 请输入新密码；
+Retype new UNIX password:   # 确认新密码；
+passwd: all authentication tokens updated successfully.  # 更改成功；
 ```
 
 比如我们让某个用户不能修改密码，可以用`-l`选项来锁定：
 
-```
-[root@localhost ~]# passwd -l linuxde    //锁定用户linuxde不能更改密码；
+```shell
+[root@localhost ~]# passwd -l linuxde     # 锁定用户linuxde不能更改密码；
 Locking password for user linuxde.
-passwd: Success           //锁定成功；
+passwd: Success            # 锁定成功；
 
-[linuxde@localhost ~]# su linuxde   //通过su切换到linuxde用户；
-[linuxde@localhost ~]$ passwd      //linuxde来更改密码；
+[linuxde@localhost ~]# su linuxde    # 通过su切换到linuxde用户；
+[linuxde@localhost ~]$ passwd       # linuxde来更改密码；
 Changing password for user linuxde.
 Changing password for linuxde
-(current) UNIX password:          //输入linuxde的当前密码；
-passwd: Authentication token manipulation error     //失败，不能更改密码；
+(current) UNIX password:           # 输入linuxde的当前密码；
+passwd: Authentication token manipulation error      # 失败，不能更改密码；
 ```
 
 再来一例：
 
-```
-[root@localhost ~]# passwd -d linuxde  //清除linuxde用户密码；
+```shell
+[root@localhost ~]# passwd -d linuxde   # 清除linuxde用户密码；
 Removing password for user linuxde.
-passwd: Success                         //清除成功；
+passwd: Success                          # 清除成功；
 
-[root@localhost ~]# passwd -S linuxde    //查询linuxde用户密码状态；
-Empty password.                         //空密码，也就是没有密码；
+[root@localhost ~]# passwd -S linuxde     # 查询linuxde用户密码状态；
+Empty password.                          # 空密码，也就是没有密码；
 ```
 
 注意：当我们清除一个用户的密码时，登录时就无需密码，这一点要加以注意。

  **C/P模式和操作** 
 
 screen的另一个很强大的功能就是可以在不同窗口之间进行复制粘贴了。使用快捷键C-a <Esc>或者C-a [可以进入copy/paste模式，这个模式下可以像在vi中一样移动光标，并可以使用空格键设置标记。其实在这个模式下有很多类似vi的操作，譬如使用/进行搜索，使用y快速标记一行，使用w快速标记一个单词等。关于C/P模式下的高级操作，其文档的这一部分有比较详细的说明。
 
 一般情况下，可以移动光标到指定位置，按下空格设置一个开头标记，然后移动光标到结尾位置，按下空格设置第二个标记，同时会将两个标记之间的部分储存在copy/paste buffer中，并退出copy/paste模式。在正常模式下，可以使用快捷键C-a ]将储存在buffer中的内容粘贴到当前窗口。

-
 ```
 
 这个语法格式可以被其中的逗号`,`分为两大部分， **Start** 部分和 **End** 部分。Start部分也由三部分组成，其中的Modifier部分就是我们之前说过的类似n和r的选项部分。我们重点说说`Start`部分的`FStart`和`C.Start`。`C.Start`也是可以省略的，省略的话就表示从本域的开头部分开始。`FStart.CStart`，其中`FStart`就是表示使用的域，而`CStart`则表示在`FStart`域中从第几个字符开始算“排序首字符”。同理，在End部分中，你可以设定`FEnd.CEnd`，如果你省略`.CEnd`，则表示结尾到“域尾”，即本域的最后一个字符。或者，如果你将CEnd设定为0(零)，也是表示结尾到“域尾”。
 
 从公司英文名称的第二个字母开始进行排序：
 
-```
+```shell
 $ sort -t ' ' -k 1.2 facebook.txt
 baidu 100 5000
 sohu 100 4500
 google 110 5000
 guge 50 3000
-
 ```
 
 使用了`-k 1.2`，表示对第一个域的第二个字符开始到本域的最后一个字符为止的字符串进行排序。你会发现baidu因为第二个字母是a而名列榜首。sohu和 google第二个字符都是o，但sohu的h在google的o前面，所以两者分别排在第二和第三。guge只能屈居第四了。
 
 只针对公司英文名称的第二个字母进行排序，如果相同的按照员工工资进行降序排序：
 
-```
+```shell
 $ sort -t ' ' -k 1.2,1.2 -nrk 3,3 facebook.txt
 baidu 100 5000
 google 110 5000
 sohu 100 4500
 guge 50 3000
-
 ```
 
 由于只对第二个字母进行排序，所以我们使用了`-k 1.2,1.2`的表示方式，表示我们“只”对第二个字母进行排序。（如果你问“我使用`-k 1.2`怎么不行？”，当然不行，因为你省略了End部分，这就意味着你将对从第二个字母起到本域最后一个字符为止的字符串进行排序）。对于员工工资进行排 序，我们也使用了`-k 3,3`，这是最准确的表述，表示我们“只”对本域进行排序，因为如果你省略了后面的3，就变成了我们“对第3个域开始到最后一个域位置的内容进行排序” 了。

 现在让我们来看一下那三个ALL到底是什么意思。第一个ALL是指网络中的主机，我们后面把它改成了主机名，它指明foobar可以在此主机上执行后面的命令。第二个括号里的ALL是指目标用户，也就是以谁的身份去执行命令。最后一个ALL当然就是指命令名了。例如，我们想让foobar用户在linux主机上以jimmy或rene的身份执行kill命令，这样编写配置文件：
 
-```
+```shell
 foobar    linux=(jimmy,rene)    /bin/kill
 ```
 
 但这还有个问题，foobar到底以jimmy还是rene的身份执行？这时我们应该想到了`sudo -u`了，它正是用在这种时候。 foobar可以使用`sudo -u jimmy kill PID`或者`sudo -u rene kill PID`，但这样挺麻烦，其实我们可以不必每次加`-u`，把rene或jimmy设为默认的目标用户即可。再在上面加一行：
 
-```
+```shell
 Defaults:foobar    runas_default=rene
 ```
 
 Defaults后面如果有冒号，是对后面用户的默认，如果没有，则是对所有用户的默认。就像配置文件中自带的一行：
 
-```
+```shell
 Defaults    env_reset
 ```
 
 另一个问题是，很多时候，我们本来就登录了，每次使用sudo还要输入密码就显得烦琐了。我们可不可以不再输入密码呢？当然可以，我们这样修改配置文件：

 vi编辑器有三种工作方式：命令方式、输入方式和ex转义方式。通过相应的命令或操作，在这三种工作方式之间可以进行转换。
 
- **命令方式** 
+**命令方式** 
 
 在Shell提示符后输入命令vi，进入vi编辑器，并处于vi的命令方式。此时，从键盘上输入的任何字符都被作为编辑命令来解释，例如，a(append）表示附加命令，i(insert）表示插入命令，x表示删除字符命令等。如果输入的字符不是vi的合法命令，则机器发出“报警声”，光标不移动。另外，在命令方式下输入的字符（即vi命令）并不在屏幕上显示出来，例如，输入i，屏幕上并无变化，但通过执行i命令，编辑器的工作方式却发生变化：由命令方式变为输入方式。
 
- **输入方式** 
+**输入方式** 
 
 通过输入vi的插入命令（i）、附加命令（a）、打开命令（o）、替换命令（s）、修改命令(c）或取代命令（r）可以从命令方式进入输入方式。在输入方式下，从键盘上输入的所有字符都被插入到正在编辑的缓冲区中，被当做该文件的正文。进入输入方式后，输入的可见字符都在屏幕上显示出来，而编辑命令不再起作用，仅作为普通字母出现。例如，在命令方式下输入字母i，进到输入方式，然后再输入i，就在屏幕上相应光标处添加一个字母i。
 
 由输入方式回到命令方式的办法是按下Esc键。如果已在命令方式下，那么按下Esc键就会发出“嘟嘟”声。为了确保用户想执行的vi命令是在命令方式下输入的，不妨多按几下Esc键，听到嘟声后再输入命令。
 
- **ex转义方式** 
+**ex转义方式** 
 
 vi和ex编辑器的功能是相同的，二者的主要区别是用户界面。在vi中，命令通常是单个字母，如a,x,r等。而在ex中，命令是以Enter；键结束的命令行。vi有一个专门的“转义”命令，可访问很多面向行的ex命令。为使用ex转义方式，可输入一个冒号（:）。作为ex命令提示符，冒号出现在状态行（通常在屏幕最下一行）。按下中断键（通常是Del键），可终止正在执行的命令。多数文件管理命令都是在ex转义方式下执行的（例如，读取文件，把编辑缓冲区的内容写到文件中等）。转义命令执行后，自动回到命令方式。例如：

+ar 允许你 在第一个 命令行 参数中 以任意 顺序 混合 指定 操作码p 和修饰符mod .
+
+只要你 愿意, 也可以 用破折号 作为 命令行 第一个 参数的 开始.
+
+p 关键字 指明 要执行的 操作, 只能 指明为 如下 之一:
+
+d      从档案中删除 模块. 通过files 指明 要删除的 模块的 名称; 如果 没有 指出 要删除的  文件  名称,  档案不会  改变  任何
+      内容.
+
+      如果 给出了'v' 修饰符,ar 会例出 它删除的 每一个 模块.
+
+m      用此 操作 在档案中移动 成员.
+      如果 某个 符号名 在档案的 多个 成员中 有定义, 那么 程序 怎样 连接 档案 文件 得到的 结果 可能是 不同的.
+      如果  没有为m 指定 修饰符, 由files 指出的 成员 将移动到 档案的末尾 ; 可以 通过 `a', `b' 或 `i' 等修饰符, 指定 成员
+      移动的 具体 位置.
+
+p      在标准 输出上 打印 档案中 指定的 成员.  如果 给出了`v' 修饰符, 在 打印 成员 内容 之前, 先打印 成员的 名字.
+      如果没有 指明files 参数, 档案中 所有的 成员 都会被 打印 出来.
+
+q      快速 追加; 增加 files 到 archive 的末尾, 不进行 替换 检查.
+      修饰符 `a' `b' 和 `i'不 影响此 操作, 新成员 始终 追加到 档案的 末尾处.
+      修饰符 `v' 可以使 ar 列出 它追加的 所有文件.
+      由于 本功能 是用于 快速操作, 即使 档案中 有 符号表 索引 也不 进行 更新; 可以 使用 `ar s' 或 ranlib 明确 要求  更新
+      这些索引.
+
+      在为快速 追加 重建 索引时,由于 有 太多 不同的 系统, 所以 GNU ar 采用 `q' 作为 `r'的一个 同义字.
+
+r      把文件  files  插入 archive ( 替换 ). 本操作与 `q' 是不同的, 如果 档案中 已有的 某个 成员与 插入 文件的 名称 相同,
+      此成员 将被删除.
+      如果 不存在 名称为 files 的文件, ar 显示 一个 错误 消息, 并且 保留 档案中 已有的 同名 成员.
+      缺省情况下, 新成员 增加到 挡案的 末尾; 可以 通过 使用 `a' `b' 或 `i' 等修饰符 指定 相对于 已有 成员的 位置.
+      通过 使用 `v' 修饰符 会为每个 插入的 文件 产生 一行 输出, 根据 输出中的 字符 `a' 或 `r' 可以 表明 该文件  是追加的
+      (没有 删除 以前的成员) 还是 替换的.
+
+t      显示  一个 archive 档案 所包含 内容的 列表 , 或 档案中的 由 files 指出的 文件 列表.  通常 只显示 成员的 名称, 如果
+      使用 `v' 修饰符, 可以 得到 成员的 权限, 时间属性, 属主, 组和 大小.
+
+      如果 没有 指出 files, 档案中的 所有 文件 都会 列出.
+
+      如果 档案中 (称为 `b.a') 有多个 同名 成员 (称为 `fie'), `ar t b.a fie' 仅仅 列出 第一个; 要看到 它们的 全部,  必须
+      要求 完整的 列表 —在本例中是 `ar t b.a'.
+
+x      从档案中 抽取  成员 (名称为 files) .  如果 使用 `v' 修饰符, ar 会列出 它抽取的 每一个 文件的 名字.
+      如果没有给出 files, 抽取 档案中 所有的 文件.
+
+可以在 操作符 p 后紧随 一定数量的 修饰符 mod 以指明 操作的 各种 行为.
+
+a      增加 文件到 档案中 已有 成员 之后  , 如果 使用了 修饰符 a, 必须在 档案 名称 archive 之前 以 membername 参数的 形式
+      给出 档案中 已有 成员的 名字.
+
+b      增加 文件到 档案中 已有 成员 之前  , 如果 使用了 修饰符 b, 必须在 档案 名称 archive 之前 以 membername 参数的 形式
+      给出 档案中 已有 成员的 名字.  (和修饰符 `i' 相同).
+
+c      建立    档案.  指定的 档案 archive 始终 会被建立, 如果 你要求 执行的是 更新, 通过 此修饰符 建立 档案时 会给出 一个
+      警告.
+      
+f      截短 档案成员的 名字.  ar 通常 允许 任意 长度的 文件名, 但这会 导致 与某些 系统上的 ar 出现 兼容性  问题,  使用  f
+      修饰符 可以 在往档案中 追加 文件时 把名字 截短.
+
+i      插入 文件到 档案中 已有 成员 之前  , 如果 使用了 修饰符 i, 必须在 档案 名称 archive 之前 以 membername 参数的 形式
+      给出 档案中 已有 成员的 名字.  (与修饰符 `b' 相同).
+
+l      接受此修饰符, 但不起作用.
+
+N      使用 count 参数. 本修饰符 用于 在档案中 有多个 同名 成员的 情况.  删除 或抽取 档案中 给定 名字的第 count 个实例.
+
+o      抽取 成员时 保留 他们 原始的  时间属性. 如果 没有 此修饰符, 文件以抽取 的时间 作为 它的时间 属性.
+
+P      匹配 档案中的 名字时 使用 完整的 路径名.  ar 不能 建立 使用 完整 路径名的 档案  (这不符合  POSIX  标准),  但其它的
+      档案  工具  能够建立, 本选项 会使 ar 在抽取 由其它 工具 建立的 档案 文件时, 使用完整的 路径名 去匹配 档案中 成员的
+      名字.
+
+s      即使 没有对 档案 进行 改变, 用本 修饰符 也可以 往档案中 写一个 目标 文件的 索引 或更新 已经 存在的  索引.   可以与
+      其它 操作 一起 使用 本修饰符, 也可以 单独使用.  对一个 档案 执行 `ar s' 与执行 `ranlib' 等价.
+
+S      不生成  档案的 符号表. 这可以 加速 建立 大的档案 文件的 过程,但这样 建立的 档案 不能被 连接器 使用, 为建立 符号表,
+      在最后 执行 `ar' 时应该 不用 `S' 修饰符, 或者 对档案 执行 一次 `ranlib' .
+
+u      通常ar r... 把所有 列出的 文件 插入到 档案中, 如果 希望 仅仅 插入比 档案中 已有 成员 更新的  文件时,  就应该  使用
+      此修饰符.   `u'  修饰符  仅允许  与 `r' (替换) 操作 一起 使用.  某些 情况下, 由于 用 `q' 操作 比较 文件的 时间属性
+      会失去 速度上的 优势, 所以 不允许 执行 `qu' 组合操作.
+
+v      使用本修饰符可以进行 冗余的 操作。附加了此修饰符时，很多操作会显示 更多的消息，如处理的文件名等。
+V      显示 ar 的版本号。

 **arp 命令** 是 Address Resolution Protocol，地址解析协议，是通过解析网络层地址来找寻数据链路层地址的一个网络协议包中极其重要的网络传输协议。而该命令可以显示和修改 arp 协议解析表中的缓冲数据。
 
+这个核心协议模块实现RFC826中定义的 Address Resolution Protocol [译注：即TCP/IP的第三层到第一层的地址转换协议]，用于在直接相连的网络中换第二层硬件地址和 Ipv4 协议地址之间的转换。 用户除非想对其进行配置，否则一般不会直接操作这个模块。
+
+实际上，它提供对核心中其它协议的服务。
+
+用户进程可以使用 packet(7) 的 sockets，收到 ARP 包（译注：一译分组）。 还有一种机制是使用 netlink(7) sockets，在用户空间管理 ARP 缓存的机制。我们也可以通过 ioctl (2) 控制任意 PF_INET socket上的 ARP 表
+
+ARP 模块维护一个硬件地址到协议地址映射的缓存。这个缓存有大小限制，所以不常用的和旧的记录（Entry）将被垃圾收集器清除（garbage-collected），垃圾收集器永远不能删除标为永久的记录。我们可以使用ioctls直接操纵缓冲， 并且其性状可以用下面定义的 sysctl 调节。
+
+如果在限定的时间（见下面的sysctl）内，一条现存映射没有肯定反馈时， 则认为相邻层的缓存记录失效。 为了再次向目标发送数据，ARP将首先试着询问本地arp进程 app_solicit 次，获取更新了的 MAC（介质访问控制）地址。 如果失败，并且旧的MAC地址是已知的，则发送 ucast_solicit 次的 unicast probe。如果仍然失败，则将向网络广播一个新的ARP请求,此时要 有待发送数据的队列
+
+如果 Linux 接到一个地址请求，而且该地址指向 Linux 转发的地址，并且接收接口打开了代理 arp 时，Linux 将自动添加一条非永久的代理 arp 记录；如果存在拒绝到目标的路由，则不添加代理 arp 记录。

 ## 补充说明
 
-**bzip2命令** 用于创建和管理（包括解压缩）“.bz2”格式的压缩包。我们遇见Linux压缩打包方法有很多种，以下讲解了Linux压缩打包方法中的Linux bzip2命令的多种范例供大家查看，相信大家看完后会有很多收获。
+**bzip2命令** 用于创建和管理（包括解压缩）“.bz2”格式的压缩包。
+
+bzip2 采用 Burrows-Wheeler 块排序文本压缩算法和 Huffman 编码方式压缩文件。 压缩率一般比基于 LZ77/LZ78 的压缩软件好得多，其性能接近 PPM 族统计类压缩软件。
+
+命令行参数有意设计为非常接近 GNU gzip 的形式，但也不完全相同。
+
+bzip2 从命令行读入文件名和参数。 每个文件被名为 "原始文件名.bz2" 的压缩文件替换。 每个压缩文件具有与原文件相同的修改时间、 权限， 如果可能的话，还具有相同的属主， 因此在解压缩时这些特性将正确地恢复。 在某些文件系统中， 没有权限、 属主或时间的概念， 或者对文件名的长度有严格限制， 例如 MSDOS，在这种情况下，bzip2 没有保持原文件名、 属主、 权限以及时间的机制， 从这个意义上说，bzip2 对文件名的处理是幼稚的。
+
+bzip2 和 bunzip2 在缺省情况下不覆盖已有的文件。 如果想覆盖已有的文件，要指定 -f 选项。
+
+如果未指定文件名， bzip2 将压缩来自标准输入的数据并写往标准输出。在这种情况下， bzip2 会拒绝将压缩结果写往终端，因为这完全无法理解并且是没有意义的。
+
+bunzip2 (以及 bzip2 -d) 对所有指定的文件进行解压缩处理。不是由 bzip2 产生的文件将被忽略，同时发出一个警告信息。 bzip2 按下列方式由压缩文件名确定解压后的文件名：
+
+```shell
+filename.bz2    解压成   filename
+filename.bz     解压成   filename
+filename.tbz2   解压成   filename.tar
+filename.tbz    解压成   filename.tar
+anyothername    解压成   anyothername.out
+```
+
+如果文件名的后缀不是下列之一： .bz2, .bz, .tbz2 或 .tbz, .bzip2 将抱怨无法确定原始文件名，并采用原文件名加 .out 作为解压缩文件名。
+
+在压缩时，如果不提供文件名，bzip2 将从标准输入读取数据，压缩结果写往标准输出。
+
+bzip2 采用 32 位 CRC 校验码作自我检查，以确认解压后的文件与原始文件相同。 这可用于检测压缩文件是否损坏，并防止 bzip2 中未知的缺陷（运气好的话这种可能性非常小）。   数据损坏而未检测到的几率非常之小，  对于每个被处理的文件大约是四十亿分之一。  检查是在解压缩时进行的，因此它只能说明某个地方出问题了。 它能帮助恢复原始未压缩的数据。可以用 bzip2recover 来尝试从损坏的文件中恢复数据。
+
+返回值：正常退出返回 0， 出现环境问题返回 1 （文件未找到，非法的选项，I/O错误等）， 返回 2 表明压缩文件损坏，出现导致 bzip2 紧急退出的内部一致性错误（例如缺陷）时返回 3。
 
 ### 语法  
 
 ```shell
-bzip2(选项)(参数)
+bzip2 [ -cdfkqstvzVL123456789 ] [ filenames ...  ]
 ```
 
 ### 选项  
 
 ```shell
--c或——stdout：将压缩与解压缩的结果送到标准输出；
--d或——decompress：执行解压缩；
--f或-force：bzip2在压缩或解压缩时，若输出文件与现有文件同名，预设不会覆盖现有文件。若要覆盖。请使用此参数；
--h或——help：在线帮助；
--k或——keep：bzip2在压缩或解压缩后，会删除原始文件。若要保留原始文件，请使用此参数；
--s或——small：降低程序执行时内存的使用量；
--t或——test：测试.bz2压缩文件的完整性；
--v或——verbose：压缩或解压缩文件时，显示详细的信息；
--z或——compress：强制执行压缩；
--V或——version：显示版本信息；
---repetitive-best：若文件中有重复出现的资料时，可利用此参数提高压缩效果；
---repetitive-fast：若文件中有重复出现的资料时，可利用此参数加快执行效果。
+-c --stdout
+    # 将数据压缩或解压缩至标准输出。
+
+-d --decompress
+    # 强制解压缩。 bzip2, bunzip2 以及 bzcat 实际上是同一个程序，进行何种操作将根据程序名确定。  指定该选项后将不考虑这一机制，强制 bzip2 进行解压缩。
+
+-z --compress
+    # -d 选项的补充：强制进行压缩操作，而不管执行的是哪个程序。
+
+-t --test
+    # 检查指定文件的完整性，但并不对其解压缩。 实际上将对数据进行实验性的解压缩操作，而不输出结果。
+
+-f --force
+    # 强制覆盖输出文件。通常 bzip2 不会覆盖已经存在的文件。该选项还强制 bzip2 打破文件的硬连接，缺省情况下 bzip2 不会这么做。
+
+-k --keep
+    # 在压缩或解压缩时保留输入文件（不删除这些文件）。
+
+-s --small
+    # 在压缩、解压缩及检查时减少内存用量。采用一种修正的算法进行压缩和测试，每个数据块仅需要 2.5 个字节。这意味着任何文件都可以在 2300k
+    # 的内存中进行解压缩， 尽管速度只有通常情况下的一半。
+
+    # 在压缩时，-s将选定 200k 的块长度，内存用量也限制在 200k 左右， 代价是压缩率会降低。 总之，如果机器的内存较少（8兆字节或更少），
+    # 可对所有操作都采用-s选项。参见下面的内存管理。
+
+-q --quiet
+    # 压制不重要的警告信息。属于 I/O 错误及其它严重事件的信息将不会被压制。
+
+-v --verbose
+    # 详尽模式 -- 显示每个被处理文件的压缩率。 命令行中更多的 -v 选项将增加详细的程度， 使 bzip2 显示出许多主要用于诊断目的信息。
+
+-L --license -V --version
+    # 显示软件版本，许可证条款及条件。
+
+-1 to -9
+    # 在压缩时将块长度设为 100 k、200 k ..  900 k。 对解压缩没有影响。参见下面的内存管理。
+
+-- # 将所有后面的命令行变量看作文件名，即使这些变量以减号"-"打头。 可用这一选项处理以减号"-"打头的文件名， 例如：bzip2 -- -myfilename.
+
+--repetitive-fast --repetitive-best
+    # 这些选项在 0.9.5 及其以上版本中是多余的。 在较早的版本中，这两个选项对排序算法的行为提供了一些粗糙的控制，有些情况下很有用。 0.9.5
+    # 及其以上版本采用了改进的算法而与这些选项无关。
 ```

+-d：显示内建命令的简要描述。
+-m：按照man手册的格式输出内建命令的帮助信息。
+-s：仅输出内建命令的命令格式。

 ### 参数  
 
-内部命令：指定需要显示帮助信息的shell内部命令。
+bash内建命令（可以为多个，请用空格分隔开）。
+
+### 常见问题
+
+Q：有哪些命令是bash内建命令？我如何判断一个命令是否为bash内建命令？
+
+A：您可以在终端使用 'man builtin' 或 'man builtins' 来获取；您可以查看bash内建命令 'type' 的帮助信息。
+
+Q：那么help命令本身的帮助信息如何获取？
+
+A：把help作为参数传给help命令；）
+
+Q：为什么echo也可以用 'man echo' 来查看帮助信息？
+
+A：因为除了bash内建的echo，GNU/linux的coreutils包里也有该命令；在echo的man手册中，DESCRIPTION段落的 'NOTE' 也提示了和同名内建的不同。
+
+PS：当你在shell脚本里定义了一个叫 'echo' 的函数，那么调用的时候优先级会如何呢？
+
+```shell
+#!/bin/bash
+#type也是内建命令
+type -t echo
+echo(){
+    printf "123\n"
+}
+type -t echo
+```
+
+```shell
+#输出结果
+builtin
+function
+```
+
+函数优先于内建命令，内建命令优先于外部命令。
+
+Q：我需要获得更多的bash的相关帮助信息
+
+A：限于篇幅和主题，您可以在终端执行 'man bash' ， 'info bash' ，[访问bash官方网站](http://www.gnu.org/software/bash/)，以及搜索引擎等。

 hping3支持非常丰富的端口探测方式，nmap拥有的扫描方式hping3几乎都支持（除开connect方式，因为Hping3仅发送与接收包，不会维护连接，所以不支持connect方式探测）。而且Hping3能够对发送的探测进行更加精细的控制，方便用户微调探测结果。当然，Hping3的端口扫描性能及综合处理能力，无法与Nmap相比。一般使用它仅对少量主机的少量端口进行扫描。
 
-#### Idle扫描  
+### # Idle扫描
 
 Idle扫描（Idle Scanning）是一种匿名扫描远程主机的方式，该方式也是有Hping3的作者Salvatore Sanfilippo发明的，目前Idle扫描在Nmap中也有实现。
 
 该扫描原理是：寻找一台idle主机（该主机没有任何的网络流量，并且IPID是逐个增长的），攻击端主机先向idle主机发送探测包，从回复包中获取其IPID。冒充idle主机的IP地址向远程主机的端口发送SYN包（此处假设为SYN包），此时如果远程主机的目的端口开放，那么会回复SYN/ACK，此时idle主机收到SYN/ACK后回复RST包。然后攻击端主机再向idle主机发送探测包，获取其IPID。那么对比两次的IPID值，我们就可以判断远程主机是否回复了数据包，从而间接地推测其端口状态。

 带宽测试通常采用UDP模式，因为能测出极限带宽、时延抖动、丢包率。在进行测试时，首先以链路理论带宽作为数据发送速率进行测试，例如，从客户端到服务器之间的链路的理论带宽为100Mbps，先用`-b 100M`进行测试，然后根据测试结果（包括实际带宽，时延抖动和丢包率），再以实际带宽作为数据发送速率进行测试，会发现时延抖动和丢包率比第一次好很多，重复测试几次，就能得出稳定的实际带宽。

 ===
 
-用来设置指令的别名
+定义或显示别名。
 
-## 补充说明
+## 主要用途
 
-**alias命令** 用来设置指令的别名。我们可以使用该命令可以将一些较长的命令进行简化。使用alias时，用户必须使用单引号`''`将原来的命令引起来，防止特殊字符导致错误。
+- 使用该命令可以将一些较长的命令进行简化。
+- 定义一个或多个别名。
+- 修改一个或多个已定义别名的值。
+- 显示一个或多个已定义别名。
+- 显示全部已定义的别名。
 
-alias命令的作用只局限于该次登入的操作。若要每次登入都能够使用这些命令别名，则可将相应的alias命令存放到bash的初始化文件`/etc/bashrc`中。
 
 ###  语法 
 
 ```shell
-alias(选项)(参数)
+alias [-p] [name[=value] ...]
 ```
 
 ###  选项 
 
-```shell
--c string 如果有 -c 选项，那么命令将从 string 中读取。如果 string 后面有参数 (argument)，它们将用于给位置参数 (positional
-         parameter，以 $0 起始) 赋值。
--i        如果有 -i 选项，shell 将交互地执行 ( interactive )。
--l        选项使得 bash 以类似登录 shell (login shell) 的方式启动 (参见下面的 启动(INVOCATION) 章节)。
--r        如果有 -r 选项，shell 成为受限的 ( restricted ) (参见下面的 受限的shell(RESTRICTED SHELL) 章节)。
--s        如果有  -s  选项，或者如果选项处理完以后，没有参数剩余，那么命令将从标准输入读取。   这个选项允许在启动一个交互
-         shell 时可以设置位置参数。
--D        向标准输出打印一个以    $    为前导的，以双引号引用的字符串列表。    这是在当前语言环境不是    C    或    POSIX
-         时，脚本中需要翻译的字符串。 这个选项隐含了 -n 选项；不会执行命令。
-[-+]O [shopt_option]
-         shopt_option 是一个 shopt 内建命令可接受的选项  (参见下面的  shell  内建命令(SHELL  BUILTIN  COMMANDS)  章节)。
-         如果有     shopt_option，-O     将设置那个选项的取值；    +O    取消它。    如果没有给出    shopt_option，shopt
-         将在标准输出上打印设为允许的选项的名称和值。 如果启动选项是 +O，输出将以一种可以重用为输入的格式显示。
---        -- 标志选项的结束，禁止其余的选项处理。任何 -- 之后的参数将作为文件名和参数对待。参数 - 与此等价。
-
-Bash 也解释一些多字节的选项。在命令行中，这些选项必须置于需要被识别的单字符参数之前。
-
---dump-po-strings
-      等价于 -D，但是输出是 GNU gettext po (可移植对象) 文件格式
---dump-strings
-      等价于 -D
---help 在标准输出显示用法信息并成功退出
---init-file file
---rcfile file
-      如果 shell 是交互的，执行 file 中的命令，而不是标准的个人初始化文件 ~/.bashrc (参见下面的 启动(INVOCATION) 章节)
-
---login
-      等价于 -l
-
---noediting
-      如果 shell 是交互的，不使用 GNU readline 库来读命令行
-
---noprofile
-      不读取系统范围的启动文件  /etc/profile  或者任何个人初始化文件  ~/.bash_profile,  ~/.bash_login,   或   ~/.profile
-      。默认情况下， bash 在作为登录 shell 启动时读取这些文件 (参见下面的 启动(INVOCATION) 章节)
-
---norc 如果 shell 是交互的，不读取/执行个人初始化文件 ~/.bashrc 这个选项在 shell 以 sh 命令启动时是默认启用的
-
---posix
-      如果默认操作与 POSIX 1003.2 标准不同的话，改变 bash 的行为来符合标准 (posix mode)
-
---restricted
-      shell 成为受限的 (参见下面的 受限的shell(RESTRICTED SHELL) 章节)
-
---rpm-requires
-      产生一个为使脚本运行，需要的文件的列表。 这个选项包含了 -n 选项。 它是为了避免进行编译期错误检测时的限制－－ Back‐
-      ticks, [] tests,  还有 evals 不会被解释，一些依赖关系可能丢失
-
---verbose
-      等价于 -v
-
---version
-      在标准输出显示此 bash 的版本信息并成功退出。

+```
 
-### 小结
 
-alias这个命令是shell的内建命令，可以根据自己的使用习惯设置一些别名，需要注意的就是和其他命令冲突的情况。
+Q&A
 
+Q：如何删除别名？
 
-#### 一、 范例演示
+A：请查看 `unalias` 命令。
 
-在使用和维护Linux系统过程中，我们常常希望根据自己的需要来定义一些命令，那么这样的操作是不是很难呢？其实不是，系统已经为我们设置好了相关的命令，下面小编就以CentOS6.4系统为例，为大家演示如何创建自己的命令。
+Q：如果我要显示一到多个别名，但不知道其中是否有未定义的该怎么办？
 
-#### 二、 自定义命令简介
+A：正常执行就是了，alias不会因为有一个未定义的别名就结束对剩余参数的执行。
 
-CentOS系统下的创建自定义命令其实比较简单，使用的命令就是alias，具体使用的方法就是 alias 自定义命令名=‘命令’。但是需要注意的是，在自定义之前需要查看自定义的命令名是否是系统已经使用的命令名，否则会冲突，另外一个就是定期清理不需要的自定义命令名。
+Q：如果我这么定义 `alias cd='ls' ls='cd'` ，会有什么后果？
 
+A：运行cd依然会切换目录，运行ls依然会列出文件夹的内容；不要这样定义；
 
-#### 三、 演示举例
 
-假定系统操作员希望进行如下操作：
+### 注意
 
-1.进入目录 `/root`  
-2.查看目录下文件  
-3.切换回根目录  
- 
-通常这需要三条命令 `cd /root`, `ls`, `cd /` ，如果需要经常使用那么我们可以通过自定义命令的方式用一条命令完成全部操作。
+1. ***请不要用这个命令对包括你自己在内的任何人开恶意的玩笑，原因如下：***
 
-#### 四、 操作过程
+> 如果终端环境中存在别名，那么在其中使用 `source` 命令调用bash脚本会出现以下行为：当执行的命令存在别名时，会按照别名的值调用执行；
+>
+> 通过 `sh` 方式调用的bash脚本或直接运行当前用户有执行权限的脚本不受终端环境的别名影响。
 
+2. 建议您不要对 `mv cp rm` 等命令的别名设置危险的 `-f` 选项。
 
-首先使用命令 `type` 自定义命令名 ，查看自定义命令名是否被系统占用。从图中可以看出test命令名已被系统占用，所以不能使用，而 `loo` 这个命令名经查询可以使用。
+3. 该命令是bash内建命令，相关的帮助信息请查看 `help` 命令。
 
-使用命令alias创建自定义命令：`alias loo='cd /root;ls;cd /'` 。需要注意的是命令的使用格式，分号与分号之间是没有空格的。
+4. 需要注意的和其他命令冲突的情况。
 
-测试一下自定义命令，当输入命令 `loo` 时，发现系统依次完成了 `cd /root`、`ls`、`cd /` 三条命令，说明设置成功。同时也可直接使用命令 `alias` 查询系统中是否添加了loo这个自定义命令。
+### 其他参考链接
 
-如果希望删除这个自定义命令，可以使用命令 `unalias` 自定义命令名 来完成。执行之后发现，`loo` 命令已不存在，同时自定义命令库中也没有 `loo` 命令。

+## export
 
-设置或显示系统环境变量
+为shell变量或函数设置导出属性。
 
-## 补充说明
+### 概要
 
-**export命令** 用于将shell变量输出为环境变量，或者将shell函数输出为环境变量。
+export [-fn] [name[=word]]...
 
-一个变量创建时，它不会自动地为在它之后创建的shell进程所知。而命令export可以向后面的shell传递变量的值。当一个shell脚本调用并执 行时，它不会自动得到原为脚本（调用者）里定义的变量的访问权，除非这些变量已经被显式地设置为可用。export命令可以用于传递一个或多个变量的值到任何后继脚本。
+export -p
 
-###  语法
+### 主要用途
 
+- 新建一到多个变量并设置导出属性。

+export返回true除非你提供了非法选项或非法名称。
+
+### 例子
+
+常见用法
 ```shell
-export(选项)(参数)
+# 显示全部拥有导出属性的变量。
+# export -p
+# export
+# 显示全部拥有导出属性的函数。
+# export -pf
 ```
 
-###  选项
 
 ```shell
--f：代表[变量名称]中为函数名称；
--n：删除指定的变量。变量实际上并未删除，只是不会输出到后续指令的执行环境中；
--p：列出所有的shell赋予程序的环境变量。
+#首先删除要演示的变量名
+#unset a b
+#新建变量的同时增加导出属性
+export a b=3
+#当然也可以这样
+b=3
+export b
+
+#修改拥有导出属性的变量的值
+export a=5 b=7
+#当然也可以直接赋值修改
+a=5;b=7
+
+#删除变量的导出属性
+export -n a b
 ```
 
-###  参数
 
-变量：指定要输出或者删除的环境变量。
+```
+#首先删除要演示的函数名
+unset func_1 func_2
+#创建函数
+function func_1(){ echo '123'; }
+function func_2(){ echo '890'; }
+
+#为已定义函数增加导出属性
+export -f func_1 func_2
+
+#删除函数的导出属性
+export -fn a b
+```
+
+### 错误用法
+
+- 对未定义的函数添加导出属性。
+
+- 对没有导出属性的函数/变量执行删除导出属性操作。
+
+- 在`--`后使用选项。
+
+
+### Q&A
+
+Q：对变量或函数设置导出属性有什么用？
+
+A：它们会成为环境变量，可以在脚本中访问它们，尤其是脚本中调用的子进程需要时。（ **参考链接4** ）
+
+
+Q：如果我编写的脚本修改了已有的环境变量的值，那么执行它会在当前终端生效吗？会影响之前以及之后打开的终端吗？
+
+A：只有通过`source`方式调用的脚本会生效，您可以查看`source`命令获得更多信息；其他方式只是在子shell中执行。
+之前的不会影响，之后的除非是修改了`~/.bashrc`这种启动终端时加载的脚本。（ **参考链接1** ）
+
+
+Q：我脚本文件中调用`~/.bashrc`中定义的函数和变量。为什么在新打开的终端中通过 `sh` 方式调用该脚本或直接运行
+这个当前用户有执行权限的脚本却不能使用这些函数和变量？
+
+A：请在`~/.bashrc`文件中增加export它们的语句。另请参阅 **知识点** 段落。
+
+
+Q：列表和关联数组也可以设置导出属性吗？
+
+A：是可以的（如果你的bash支持它们），不过有些问题（ **参考链接2** ）。
+
+
+Q：为什么我在查看变量或函数导出属性的时候显示的开头是`declare`？
+
+A：因为`declare`也能够设置变量或函数的导出属性，详见`declare`命令。
+
+
+### 注意
+
+1. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。
+
+### 知识点
+
+在 `info bash`或 [bash在线文档](http://www.gnu.org/software/bash/manual/bash.html) 的
+ `3.7.3`节提到了shell执行环境，其中涉及变量和函数的内容如下
+
+> - shell parameters that are set by variable assignment or with set or inherited from the shell’s parent in the environment
+> - shell functions defined during execution or inherited from the shell’s parent in the environment
+
+那么第一句话中的参数又和变量有什么关系呢？在`3.4`节第一段中提到：
+
+>  A variable is a parameter denoted by a name.
+
+变量是有名字的参数。
+
+那么子shell确实继承了父shell中带有导出属性的变量或函数。
+
+可参考链接 [执行脚本方式的区别](https://blog.csdn.net/soaringlee_fighting/article/details/78759448)

-###  语法
+### 主要用途

+
+#### 参数
+

+
+#### 返回值
+
+source返回文件最后一个命令的返回值，如果文件不能读取则会失败
+
+#### 错误用法
+
+- 文件在`$PATH`中找不到。
+
+- 文件未给出。
 
 ### 例子
 
-读取和执行/root/.bash_profile文件。
+- 在一些工具的执行过程中，会把环境变量设置以"export XXX=XXXXXX"或"declare XXX=XXXXXX"的形式导出到
+一个文件中，然后用source加载该文件内容到执行环境中。

+### Q&A
+
+Q：`source`和`sh`在执行文件方面有什么区别？
+
+A：`sh`的执行是在子shell中，`source`会使得被执行文件的变量及函数加载进当前终端环境内（除去函数内local修饰的变量等）；建议您参考`export`命令的 **知识点** 部分

-linux shell命令执行时，shell总是先在自己的shell builtin中查找该命令，如果找到则执行该命令；如果找不到该命令，则会从环境变量$PATH指定的路径中依次去查找待执行的命令。因为了解了这一点，所以看起来好像没有办法编写用户自己的命令来替代shell builtin命令。幸运的是，有了enable命令我们就能做到了。

+
+1. 关于同名命令调用的优先级的知识，请先参考`builtin`命令的*提示*部分，然后继续阅读下面部分；
+
+  当内建命令`echo`没有禁用时，如果要调用外部命令`echo`，只能这样写`/usr/bin/echo`；
+
+  当我们禁用了`echo`后，优先级顺序变成了这样：
+
+  函数 > 外部命令
+
+  如果执行命令的环境没有`echo`函数，那么调用的`echo`就是外部命令。
+
+2. 该命令是bash内建命令，相关的帮助信息请查看 `help` 命令。

-###  语法
+readonly -p
 
-```shell
-readonly(选项)(参数)
-```
+### 主要用途
+
+- 定义一到多个变量并设置只读属性。
+
+- 为已定义的一到多个变量设置只读属性。
+
+- 显示全部包含只读属性的变量。
 
-###  选项
+- 为已定义的一到多个函数设置只读属性。

-###  参数
+#### 参数
 
-shell变量：声明shell变量，格式为“变量名=值”。
+name（可选）：变量名或函数名。
 
-###  实例
+value（可选）：变量的值。
 
-首先使用declare命令定义shell变量"test"，并且将其值设置为"wangchujiang.com"，输入如下命令：
+#### 返回值
+
+declare返回true除非你提供了非法选项或赋值错误。具体导致异常的情况请查看**讨论**章节的**关于异常情况**。
+
+### 例子
 
 ```shell
-declare test='wangchujiang.com'    #定义并初始化shell变量
+# 声明变量，当然也欢迎您在这个网站（感谢本项目发起人 @jaywcjlove）查询linux命令。
+declare reference_website='https://wangchujiang.com/linux-command/'
+
+# 显示所有包含整型属性的变量和值。
+declare -i
+# 定义变量b并赋值为3，具有整型属性。
+declare -i b=5
+# 显示属性，返回 declare -i b="5"。
+declare -p b
+# 删除整型属性。
+declare +i b
+# 显示属性，返回 declare -- b="5"。
+declare -p b
+
+# 变量大小写属性设置的作用。
+declare -u uc_var='abc'
+declare -l lc_var='ABC'
+# 查看变量的值。
+echo "${uc_var} ${lc_var}"
+# 返回 'ABC abc';
+# 根据变量属性强制转换值的英文大小写。
+
+# 导出属性的相关内容请查看'export'命令。
+# 只读属性的相关内容请查看'readonly'命令。
 ```
 
-上面的命令执行后，再使用echo命令将该shell变量值输出，输入如下命令：
+```shell
+# 定义函数内的全局变量
+function test(){
+  declare -g a=3
+  # 或者
+  local -g b=3
+  # 或者
+  c=3
+  # 让我们查看它们的属性。
+  declare -p a b c
+}
+# 执行函数。
+test
+# 返回结果。
+# declare -- a="3"
+# declare -- b="3"
+# declare -- c="3"
+
+#定义函数外的全局变量
+declare a=3
+b=3
+declare –p a b
+# 返回结果。
+# declare -- a="3"
+# declare -- b="3"
+
+#定义局部变量
+function test2(){
+  local -i a=3
+  declare -i b=3
+}
+test2
+echo "${a} ${b}"
+# 没有该变量（已经被销毁了）
+
+# 因此，我们日常脚本中最常见的类似于'a=3'实际上是声明并赋值了一个全局变量。
+# 在接下来的 **讨论** 环节会延伸讨论全局和局部变量问题。
+```
 
 ```shell
-echo $test                        #输出shell变量的值
+# 注意，不能使用 `+a` 或 `+A` 取消数组，也不能使用 `+r` 取消只读属性。
+
+# 定义只读数组，设置属性的同时定义赋值。
+declare -ar season=('Spring' 'Summer' 'Autumn' 'Winter')
+# 或者这样。
+season=('Spring' 'Summer' 'Autumn' 'Winter')
+declare -ar season
+# 显示所有数组。
+declare -a
+
+# 定义关联数组。
+declare -A fruits=(['apple']='red' ['banana']='yellow')
+# 显示所有关联数组。
+declare -A
 ```
 
-上面的指令执行后，其输出的结果如下：
+```shell
+# 显示所有变量的属性和值并显示函数的定义，输出很长；）
+declare
+
+# 显示所有变量的属性和值。
+declare -p
+
+# 显示所有全局变量的属性和值。
+declare -g
+```
 
 ```shell
-wangchujiang.com
+# 显示全部函数名和函数定义。
+declare -f
+
+# 只显示全部函数名。
+declare -F
+
+# 定义两个函数。
+function func_a(){ echo $(date +"%F %T"); }
+function func_b(){ cd /; ls -lh --sort=time; }
+
+# 显示一到多个函数名和函数定义。
+declare -f func_a func_b
+
+# 只显示一到多个函数名。
+# 验证某个名称是否已经定义为函数时有用。
+declare -F func_a func_b
+# 最好不要让函数名和变量名相同。

+### 讨论
+
+1. 全局和局部变量
+   
+   正如上面**例子**指出的情况，我们在日常编写程序的时候需要了解这些概念，在这里
+   做个简要地介绍，当然你也可以很方便的搜索到相关内容。
+   
+   - 全局变量：在整个脚本执行期间，只要没有被删除就**一直存在**。
+   - 局部变量：在函数内定义，函数执行后就被删除。
+   
+   建议函数内使用`local`命令，函数外使用`declare`命令。
+   
+   > *不要在脚本中定义过多的全局变量，那样可能会被其他函数调用造成意料之外的后果，并且也不方便检查出来。*
+   >
+   > *更不用说缺乏必要的注释了 —— ZhuangZhu-74*

+   
+   - [全局变量的讨论](https://unix.stackexchange.com/questions/381761/what-do-declare-name-and-declare-g-do)
+   
+2. 关于`declare` `typeset` `export` `local` `readonly`命令
+   
+   为什么`declare`能做到的事，还需要定义其他这些命令呢？
+   
+   因为这样语句含义会更加明确，例如：
+   - 设置导出属性的变量时，`export var`和`declare -x var`。
+   - 在函数内声明变量时，使用`local`。
+   - 声明只读变量，使用`readonly`。
+   
+   `typeset`和`declare`命令一样。
+   
+3. 关于异常情况
+
+   有多种原因导致`declare`失败，关于这些情况可以参考[bash在线文档declare部分\(最新版\)](https://www.gnu.org/software/bash/manual/bash.html#index-declare)，或执行 `info bash`
+   查看`declare`部分最后一大串`an attempt is`开头的句子。

 let
 ===
 
-简单的计算器
+简单的计算器，执行算术表达式。
 
-## 补充说明
+## 概要
 
-**let命令** 是bash中用于计算的工具，提供常用运算符还提供了方幂`**`运算符。在变量的房屋计算中不需要加上`$`来表示变量，如果表达式的值是非0，那么返回的状态值是0；否则，返回的状态值是1。
+```shell
+let arg [arg ...]
+```
+
+## 主要用途
+
+- 执行一个或多个算术表达式。
+
+## 参数
+
+arg：算术表达式
+
+## 返回值
+
+当`let`最后一个执行的表达式的计算结果为0时返回`1`，否则返回`0`。
+当`let`执行的表达式的除数为0时，返回`1`并报错。
+
+## 运算符优先级递减表
+
+|**运算符**|**描述**|
+|:-------:|:-------:|
+|```id++, id--```|```变量后增量、变量后减量```|
+|```++id, --id```|```变量预增量、变量预减量```|
+|```-, +```|```正号、负号```|
+|```!, ~```|```逻辑否、按位取反```|
+|```**```|```幂运算```|
+|```*, /, %```|```乘法、除法、取余```|
+|```+, -```|```加法、减法```|
+|```<<, >>```|```按位左移、右移```|
+|```<=, >=, <, >```|```比较```|
+|```==, !=```|```等于、不等于```|
+|```&```|```按位与```|
+|```^```|```按位异或```|
+|```\|```|```按位或```|
+|```&&```|```逻辑与```|
+|```\|\|```|```逻辑或```|
+|```expr ? expr : expr```|```条件运算符（三元运算符）```|
+|```=, *=, /=, %=, +=, -=,```<br>```<<=, >>=, &=, ^=, \|=```|```赋值```|
 
-###  语法
+
+## 例子
 
 ```shell
-let arg [arg ...]    #arg代表运算式
+# 尝试直接在终端中执行算术表达式（就像在python的IDLE）。
+3+4
+bash：3+4：command not found...
+# 换一种方式。
+3 + 4
+bash：3：command not found...
+# 看来不行。
 ```
 
-###  用法
-
-自加操作`let no++`  
-自减操作`let no--`  
-简写形式`let no+=10`，`let no-=20`，分别等同于`let no=no+10，``let no=no-20`
+```shell
+# let命令赋值。
+let a=3**4
+echo ${a}
+# 显示81。
+# ((...))和let命令等效。
+((a=3**4))
+```
 
-###  实例
+```shell
+# let常用于变量赋值，而外部命令expr可直接返回表达式的值。
+let 3+4
+# 没有显示7。
+# 执行后显示7，注意空格。
+expr 3 + 4
+```
 
 ```shell
-#!/bin/bash
-let a=5+4 b=9-3
-echo $a $b
+# 条件表达式。
+if ((8>4)); then
+  echo '8 is greater than 4.'
+else
+  echo 'error'
+fi
+# 注意空格。
+if [[ 12 -le 10 ]]; then
+  echo 'error'
+else
+  echo '12 is greater than 10.'
+fi
 ```
 
 ```shell
-#!/bin/bash
-let "t1 = ((a = 5 + 3, b = 7 - 1, c = 15 - 4))"
-echo "t1 = $t1, a = $a, b = $b"
+# 可以通过declare命令设置整型属性的方法来进行算术运算。
+# local命令与此类似。
+
+# 没有指定整型属性，输出为字符串'a+b'。
+declare a=3 b=4 c
+c=a+b
+echo ${c}
+# 不过可以使用以下方式赋值。
+c=$((a+b))
+echo ${c}
+# 显示7
+
+# 设置了整型属性就可以直接加了。
+declare -i a=3 b=4 c
+c=a+b
+echo ${c}
+# 同上。
+declare -i a
+a=2*3
+echo ${a}
+# 显示6。
 ```
 
+### 注意
+
+1. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。
+
+2. 执行算术计算的命令除了`let`，还有外部命令`expr`、`bc`等。

-删除指定的shell变量或函数
+删除指定的shell变量或函数。
 
-## 补充说明
-
-**unset命令** 用于删除已定义的shell变量（包括环境变量）和shell函数。unset命令不能够删除具有只读属性的shell变量和环境变量。
-
-###  语法
+## 概要
 
 ```shell
-unset(选项)(参数)
+unset [-f] [-v] [-n] [name ...]
 ```
 
-###  选项
+## 主要用途
+
+- 删除一到多个shell变量（不包括只读变量）。
+- 删除一到多个shell函数。
+- 删除一到多个具有引用属性的变量（如果-n选项存在）。
+
+## 选项
 
 ```shell
--f：仅删除函数；
--v：仅删除变量。
+-f：仅删除函数。
+-v：仅删除变量（不包括只读变量）。
+-n：删除具有引用属性的变量名（如果该选项存在）。
 ```
 
-###  参数
+## 参数
 
-shell变量或函数：指定要删除的shell变量或shell函数。
+name（可选）：要删除的变量或函数。
 
-###  实例
+## 返回值
 
-使用unset命令将前面所创建的环境变量mylove及其对应的值进行删除，输入如下命令：
+返回成功除非选项错误或要删除的变量或函数有只读属性。
 
+## 例子
+
+```shell
+# 删除变量。
+declare paper_size='B5'
+unset -v paper_size
+```
 ```shell
-unset -v mylove         #删除指定的环境变量
+# 删除函数。
+function show_result(){ echo 'Last Command Return: $?'; }
+unset -f show_result
 ```
+```shell
+# 当不指定选项时，优先删除变量，如果失败则删除函数。
+declare -i aa=100
+function aa(){ echo 'aa'; }
+unset aa
+# 变量'aa'已被删除。
+declare -p aa
+# 函数'aa'存在。
+declare -F|grep aa
+```
+```shell
+# 演示unset使用-n选项，name指定了引用变量时的情况。
+declare a=3
+# 定义引用变量
+declare -n b=a
+# 查看属性，显示declare -n b="a"
+declare -p b
+# 显示3
+echo ${b}
+# 显示a
+echo ${!b}
+# 指定-n选项时
+unset -n b
+# 引用变量b已被删除
+declare -p b
+# 被引用的变量a未被删除
+declare -p a
+```
+
+```shell
+# 演示unset不使用-n选项，name指定了引用变量时的情况。
+declare a=3
+# 定义引用变量
+declare -n b=a
+# 查看属性，显示declare -n b="a"
+declare -p b
+# 显示3
+echo ${b}
+# 显示a
+echo ${!b}
+# 不指定-n选项时
+unset b
+# 引用变量b未被删除，显示declare -n b="a"
+declare -p b
+# 被引用的变量a被删除
+declare -p a
+```
+
+### 注意
 
-执行以上命令后，系统将删除指定的环境变量。用户可以使用env命令和grep命令对其进行查询。已经删除的环境变量再次使用指令查询时，将出现查询不到指定环境变量的输出信息。
+1. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。

+```
+
+## 主要用途
+
+- 结束for，while或until循环，可指定退出几层循环。
+
+
+## 参数
+
+n（可选）：大于等于1的整数，用于指定退出几层循环。
+
+## 返回值
+
+返回成功除非n小于1。
+
+## 例子
+
+```shell
+# break的可选参数n缺省值为1。
+# 从外层for循环继续执行。
+for((i=3;i>0;i--)); do
+  for((j=3;j>0;j--)); do
+    if((j==2)); then
+      # 换成break 1时结果一样
+      break
+    fi
+  printf "%s %s\n" ${i} ${j}
+  done
+done
+# 输出结果
+3 3
+2 3
+1 3
+```
+
+```shell
+# 当n为2时：
+# 退出两层循环，结束。
+for((i=3;i>0;i--)); do
+  for((j=3;j>0;j--)); do
+    if((j==2)); then
+      break 2
+    fi
+  printf "%s %s\n" ${i} ${j}
+  done

 550 多个 Linux 命令，内容包含 Linux 命令手册、详解、学习，值得收藏的 Linux 命令速查手册。请原谅我写了个爬虫，爬了他们家的数据 [linuxde.net](http://man.linuxde.net) ，同时进行了编辑，增加了一些数据。对他们的辛勤劳动表示敬意，个人希望能本地离线搜索，不喜欢广告，希望得到干净漂亮的预览界面，业余和工作时间需要使用大量的命令，所以干了一件看似比较愚蠢的事情，在回头有空的时候估计能做一个App？或者是命令行帮助工具？但目前还没有计划...

 cd
 ===
 
-切换用户当前工作目录
+切换用户当前工作目录。
 
-## 补充说明
-
-**cd命令** 用来切换工作目录至dirname。 其中dirName表示法可为绝对路径或相对路径。若目录名称省略，则变换至使用者的home directory(也就是刚login时所在的目录)。另外，`~`也表示为home directory的意思，`.`则是表示目前所在的目录，`..`则表示目前目录位置的上一层目录。
-
-###  语法
+## 概要
 
 ```shell
-cd (选项) (参数)
+cd [-L|[-P [-e]]] [dir]
 ```
 
-###  选项
+## 主要用途
+
+- 切换工作目录至`dir`。其中`dir`的表示法可以是绝对路径或相对路径。
+- 若参数`dir`省略，则默认为使用者的shell变量`HOME`。
+- 如果`dir`指定为`~`时表示为使用者的shell变量`HOME`，`.`表示当前目录，`..`表示当前目录的上一级目录。
+- 环境变量`CDPATH`是由冒号分割的一到多个目录，你可以将常去的目录的上一级加入到`CDPATH`以便方便访问它们；如果`dir`以`/`开头那么`CDPATH`不会被使用。
+- 当`shopt`选项`cdable_vars`打开时，如果`dir`在`CDPATH`及当前目录下均不存在，那么会把它当作变量，读取它的值作为要进入的目录。
+
+## 参数
+
+dir（可选）：指定要切换到的目录。
+
+## 选项
 
 ```shell
--p 如果要切换到的目标目录是一个符号连接，直接切换到符号连接指向的目标目录
--L 如果要切换的目标目录是一个符号的连接，直接切换到字符连接名代表的目录，而非符号连接所指向的目标目录。
-- 当仅实用"-"一个选项时，当前工作目录将被切换到环境变量"OLDPWD"所表示的目录。
+-L （默认值）如果要切换到的目标目录是一个符号连接，那么切换到符号连接的目录。
+-P 如果要切换到的目标目录是一个符号连接，那么切换到它指向的物理位置目录。
+-  当前工作目录将被切换到环境变量OLDPWD所表示的目录，也就是前一个工作目录。
 ```
 
-###  实例
+## 返回值
+
+返回状态为成功除非无法进入指定的目录。
+
+## 例子
 
 ```shell
 cd    # 进入用户主目录；
+cd /  # 进入根目录
 cd ~  # 进入用户主目录；
-cd -  # 返回进入此目录之前所在的目录；
+cd -  # 显示并返回进入此目录之前所在的目录（也就是根目录）；
 cd ..  # 返回上级目录（若当前目录为“/“，则执行完后还在“/"；".."为上级目录的意思）；
 cd ../..  # 返回上两级目录；
 cd !$  # 把上个命令的参数作为cd参数使用。
 ```
 
+关于`CDPATH`
+
+```shell
+# 设置桌面文件夹作为CDPATH的值。
+CDPATH='~/Desktop'
+# 假设我们接下来要演示涉及到的路径~和~/Desktop下没有test3文件夹，现在新建它们。
+mkdir ~/test3
+mkdir ~/Desktop/test3
+# 进入~目录。
+cd ~
+# 进入test3目录。
+cd test3
+# 执行后显示~/Desktop/test3并进入该目录，而不是~目录的test3目录。
+# 如果CDPATH存在值，那么优先在CDPATH中查找并进入第一个匹配成功的，如果全部失败那么最后尝试当前目录。
+```
+
+关于`cdable_vars`
+
+```shell
+# 打开选项。
+shopt -s cdable_vars
+# 假设当前路径以及CDPATH没有名为new_var的目录。
+new_var='~/Desktop'
+# 尝试进入。
+cd new_var
+# 关闭选项。
+shopt -u cdable_vars
+```
+
+### 注意
+
+1. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。

 umask
 ===
 
-用来设置限制新建文件权限的掩码
+显示或设置创建文件的权限掩码。
 
-## 补充说明
-
-**umask命令** 用来设置限制新建文件权限的掩码。当新文件被创建时，其最初的权限由文件创建掩码决定。用户每次注册进入系统时，umask命令都被执行， 并自动设置掩码mode来限制新文件的权限。用户可以通过再次执行umask命令来改变默认值，新的权限将会把旧的覆盖掉。
-
-###  语法 
+## 概要
 
 ```shell
-umask(选项)(参数)
+umask [-p] [-S] [mode]
 ```
 
-###  选项 
+## 主要用途
+
+- 显示当前的文件权限掩码。
+- 通过八进制数的方式设置创建文件的权限掩码。
+- 通过符号组合的方式设置创建文件的权限掩码。
+
+## 参数
+
+mode（可选）：八进制数或符号组合。
+
+## 选项 
 
 ```shell
--p：输出的权限掩码可直接作为指令来执行；
--S：以符号方式输出权限掩码。
+-p：当没有参数时指定该选项，执行产生的输出格式可复用为输入；
+-S：以符号组合的方式输出创建文件的权限掩码，不使用该选项时以八进制数的形式输出。
 ```
 
-###  参数 
+## 返回值
 
-权限掩码：指定权限掩码。
+返回状态为成功除非给出了非法选项或非法参数。
 
-###  实例 
+## 例子
 
-利用umask命令可以指定哪些权限将在新文件的默认权限中被删除。例如，可以使用下面的命令创建掩码，使得组用户的写权限，其他用户的读、写和执行权限都被取消：
+*以下的例子均假设文件权限掩码为0022。*
 
 ```shell
-umask u=, g=w, o=rwx
+# 以八进制数的形式输出创建文件的权限掩码。
+umask -p
+# 执行结果：
+umask 0022
+# 以符号组合的方式输出创建文件的权限掩码。
+umask -S
+# 执行结果：
+u=rwx,g=rx,o=rx
 ```
 
-执行该命令以后，对于下面创建的新文件，其文件主的权限未做任何改变，而组用户没有写权限，其他用户的所有权限都被取消。
+> 参考`man chmod`文档的`DESCRIPTION`段落得知：
+> - `u`符号代表当前用户。
+> - `g`符号代表和当前用户在同一个组的用户，以下简称组用户。
+> - `o`符号代表其他用户。
+> - `a`符号代表所有用户。
+> - `r`符号代表读权限以及八进制数`4`。
+> - `w`符号代表写权限以及八进制数`2`。
+> - `x`符号代表执行权限以及八进制数`1`。
+> - `+`符号代表添加目标用户相应的权限。
+> - `-`符号代表删除目标用户相应的权限。
+> - `=`符号代表添加目标用户相应的权限，删除未提到的权限。
 
-应注意：操作符“=”在umask命令和chmod命令中的作用恰恰相反。在chmod命令中，利用它来设置指定的权限，而其余权限则被删除；但是在umask命令中，它将在原有权限的基础上删除指定的权限。
+那么刚才以符号形式输出的结果`u=rwx,g=rx,o=rx`转化为八进制数等于`0755`；
 
-不能直接利用umask命令创建一个可执行的文件，用户只能在其后利用chmod命令使它具有执行权限。假设执行了命令`umask u=, g=w, o=rwx`，虽然在命令行中，没有删去文件主和组用户的执行权限，但默认的文件权限还是640（即 rw-r-----），而不是750(rwxr-x---）。但是，如果创建的是目录或者通过编译程序创建的一个可执行文件，将不受此限制。在这种情况 下，会设置文件的执行权限。
+用八进制数来设置同样的权限，`umask`需要额外的执行减法`0777 - 0755`即`0022`，而`chmod`不需要。
 
-也可以使用八进制数值来设置mode。由于在umask中所指定的权限是要从文件中删除的，所以，如果该文件原来的初始化权限是777，那么执行命令umask 022以后，该文件的权限将变为755：如果该文件原来的初始化权限是666，那么该文件的权限将变为644。
+符号组合模式的添加、删除、赋值权限。
 
-可以使用下面的命令检查新创建文件的默认权限：
+```shell
+# 添加权限：
+# 为组用户添加写权限。
+umask g+w
+# 删除权限：
+# 删除其他用户的写、执行权限
+umask o-wx
+# 赋值权限：
+# 赋值全部用户所有权限，等价于umask u=rwx,g=rwx,o=rwx
+umask a=rwx
+# 清除其他用户的读、写、执行权限。
+umask o=
+```
+
+创建文件夹、文件（假设当前目录不存在）
 
 ```shell
-umask -S
+# 创建文件
+touch test.sh
+# 查看权限，发现执行权限的设置不起作用。
+stat test.sh
+# 创建文件夹
+touch newdir
+# 查看权限，发现执行权限的设置可以起作用。
+stat newdir
 ```
 
-选项-S表示以字符形式显示当前的掩码。如果直接输入umask命令，不带任何参数，那么将以八进制形式显示当前的掩码。系统默认的掩码是0022。
+### 注意
+
+1. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。
+
+2. `chmod`用于更改已有对象的权限，`umask`影响之后新建对象的权限。
 
+3. **请谨慎使用该命令**，特别是不要取消当前用户的读取权限，那样会导致你在终端使用`TAB`键补全时报错。

 用来变更文件或目录的权限
 
-## 补充说明
-
-**chmod命令** 用来变更文件或目录的权限。在UNIX系统家族里，文件或目录权限的控制分别以读取、写入、执行3种一般权限来区分，另有3种特殊权限可供运用。用户可以使用chmod指令去变更文件与目录的权限，设置方式采用文字或数字代号皆可。符号连接的权限无法变更，如果用户对符号连接修改权限，其改变会作用在被连接的原始文件。
-
-权限范围的表示法如下：
-
-`u` User，即文件或目录的拥有者；  
-`g` Group，即文件或目录的所属群组；  
-`o` Other，除了文件或目录拥有者或所属群组之外，其他用户皆属于这个范围；  
-`a` All，即全部的用户，包含拥有者，所属群组以及其他用户；  
-`r` 读取权限，数字代号为“4”;  
-`w` 写入权限，数字代号为“2”；  
-`x` 执行或切换权限，数字代号为“1”；  
-`-` 不具任何权限，数字代号为“0”；  
-`s` 特殊功能说明：变更文件或目录的权限。
-
-###  语法 
-
-```
-chmod(选项)(参数)
-```
-
-###  选项 
+## 概要
 
 ```shell
-u  # 操作对象简称，用户user，文件或目录的所有者。
-g  # 操作对象简称，同组用户group，文件或目录所属群组
-o  # 操作对象简称，其它用户others
-a  # 操作对象简称，所有用户all，系统默认使用此项
-+  # 权限操作符，添加某些权限
--  # 权限操作符，取消某些权限
-=  # 权限操作符，设置文件的权限为给定的权限
-r  # 权限设定（英文），表示可读权限
-w  # 权限设定（英文），表示可写权限
-x  # 权限设定（英文），表示可执行权限
--  # 权限设定（英文字符），表示没有权限
-X  # 权限设定，如果目标文件是可执行文件或目录，可给其设置可执行权限
-s  # 权限设定，设置权限suid和sgid，使用权限组合“u+s”设定文件的用户的ID位，“g+s”设置组ID位
-t  # 权限设定，只有目录或文件的所有者才可以删除目录下的文件
--c或——changes    # 效果类似“-v”参数，但仅回报更改的部分，如果文件权限已经改变，显示其操作信息；
--f或--quiet或——silent # 操作过程中不显示任何错误信息；
--R或——recursive  # 递归处理，将指令目录下的所有文件及子目录一并处理；
--v或——verbose    # 显示命令运行时的详细执行过程；
---reference=<参考文件或目录> # 把指定文件或目录的所属群组全部设成和参考文件或目录的所属群组相同；
-<权限范围>+<权限设置> # 开启权限范围的文件或目录的该选项权限设置；
-<权限范围>-<权限设置> # 关闭权限范围的文件或目录的该选项权限设置；
-<权限范围>=<权限设置> # 指定权限范围的文件或目录的该选项权限设置；
---help    # 显示帮助信息
---version # 显示版本信息
+chmod [OPTION]... MODE[,MODE]... FILE...
+chmod [OPTION]... OCTAL-MODE FILE...
+chmod [OPTION]... --reference=RFILE FILE...
 ```
 
-###  参数 
+## 主要用途
 
-权限模式：指定文件的权限模式；  
-文件：要改变权限的文件。
+- 通过符号组合的方式更改目标文件或目录的权限。
+- 通过八进制数的方式更改目标文件或目录的权限。
+- 通过参考文件的权限来更改目标文件或目录的权限。
 
-###  知识扩展和实例 
+## 参数
 
-Linux用 户分为：拥有者、组群(Group)、其他（other），Linux系统中，预设的情況下，系统中所有的帐号与一般身份使用者，以及root的相关信 息， 都是记录在`/etc/passwd`文件中。每个人的密码则是记录在`/etc/shadow`文件下。 此外，所有的组群名称记录在`/etc/group`內！
+mode：八进制数或符号组合。
 
-linux文件的用户权限的分析图
+file：指定要更改权限的一到多个文件。
+
+## 选项 
 
 ```shell
-  -rw-r--r--   1 user  staff   651 Oct 12 12:53 .gitmodules
-# ↑╰┬╯╰┬╯╰┬╯
-# ┆ ┆  ┆  ╰┈ 0 其他人
-# ┆ ┆  ╰┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ g 属组
-# ┆ ╰┈┈┈┈ u 属组
-# ╰┈┈ 第一个字母 `d` 代表目录，`-` 代表普通文件
+-c, --changes：当文件的权限更改时输出操作信息。
+--no-preserve-root：不将'/'特殊化处理，默认选项。
+--preserve-root：不能在根目录下递归操作。
+-f, --silent, --quiet：抑制多数错误消息的输出。
+-v, --verbose：无论文件是否更改了权限，一律输出操作信息。
+--reference=RFILE：使用参考文件或参考目录RFILE的权限来设置目标文件或目录的权限。
+-R, --recursive：对目录以及目录下的文件递归执行更改权限操作。
+--help：显示帮助信息并退出。
+--version：显示版本信息并退出。
 ```
 
-例：rwx　rw-　r--
+## 返回值
 
-r=读取属性　　//值＝4  
-w=写入属性　　//值＝2  
-x=执行属性　　//值＝1
+返回状态为成功除非给出了非法选项或非法参数。
 
-```shell
-chmod u+x,g+w f01　　# 为文件f01设置自己可以执行，组员可以写入的权限
-chmod u=rwx,g=rw,o=r f01
-chmod 764 f01
-chmod a+x f01　　    # 对文件f01的u,g,o都设置可执行属性
-```
+## 例子 
 
-文件的属主和属组属性设置
+> 参考`man chmod`文档的`DESCRIPTION`段落得知：
+> - `u`符号代表当前用户。
+> - `g`符号代表和当前用户在同一个组的用户，以下简称组用户。
+> - `o`符号代表其他用户。
+> - `a`符号代表所有用户。
+> - `r`符号代表读权限以及八进制数`4`。
+> - `w`符号代表写权限以及八进制数`2`。
+> - `x`符号代表执行权限以及八进制数`1`。
+> - `X`符号代表如果目标文件是可执行文件或目录，可给其设置可执行权限。
+> - `s`符号代表设置权限suid和sgid，使用权限组合`u+s`设定文件的用户的ID位，`g+s`设置组用户ID位。
+> - `t`符号代表只有目录或文件的所有者才可以删除目录下的文件。
+> - `+`符号代表添加目标用户相应的权限。
+> - `-`符号代表删除目标用户相应的权限。
+> - `=`符号代表添加目标用户相应的权限，删除未提到的权限。
 
 ```shell
-chown user:market f01　　# 把文件f01给user，添加到market组
-ll -d f1  查看目录f1的属性
-```
-
-
-将`/home/wwwroot/`里的所有文件和文件夹设置为`755`权限
+linux文件的用户权限说明
 
-(1)直接指定路径修改
+# 查看当前目录（包含隐藏文件）的长格式。
+ls -la
+  -rw-r--r--   1 user  staff   651 Oct 12 12:53 .gitmodules
+# 
+# 第1位如果是d则代表目录，是-则代表普通文件，更多详情请参阅info ls（ls命令的info文档）。
+# 第2到4位代表当前用户的权限。
+# 第5到7位代表组用户的权限。
+# 第8到10位代表其他用户的权限。
+```
 
 ```shell
-chmod -R  755 /home/wwwroot/*
+# 添加组用户的写权限
+chmod g+w ./test.log
+# 删除其他用户的所有权限
+chmod o= ./test.log
+# 使得所有用户都没有写权限
+chmod a-w ./test.log
+# 当前用户具有所有权限，组用户有读写权限，其他用户只有读权限
+chmod u=rwx, g=rw, o=r ./test.log
+# 等价的八进制数表示：
+chmod 754 ./test.log
+# 将目录以及目录下的文件都设置为所有用户拥有读写权限
+# 注意，使用'-R'选项一定要保留当前用户的执行和读取权限，否则会报错！
+chmod -R a=rw ./testdir/
+# 根据其他文件的权限设置文件权限
+chmod --reference=./1.log  ./test.log
 ```
 
-(2)手动进入该目录修改权限（并显示详细过程）
+### 注意
 
+1. 该命令是`GNU coreutils`包中的命令，相关的帮助信息请查看`man chmod`或`info chmod`。
 
-```shell
-cd /home/wwwroot
-chmod -Rv  755 *       #注意：“*”表示通配符，指的是所有文件和文件
-sudo chmod o+rw /shared #设置文件夹权限以保证其余用户可以访问它。
-```
+2. 符号连接的权限无法变更，如果用户对符号连接修改权限，其改变会作用在被连接的原始文件。
 
+3. 使用`-R`选项一定要保留当前用户的执行和读取权限，否则会报错！

 执行bash内建命令。
 
-## 补充说明
-
-**builtin命令** 用于执行指定的bash内建命令，并返回内部命令的返回值。builtin命令在使用时，Linux中同名的外部命令及同名的shell函数失效。
-
-###  语法
+## 概要
 
 ```shell
-builtin(bash内建命令)(参数)
+builtin [shell-builtin [arg ...]]
 ```
 
-###  参数
+## 主要用途
+
+- 用于执行指定的bash内建命令。
+- `builtin`命令调用的bash内建命令优先于同名的外部命令及同名的shell函数。
+
+## 参数
 
-bash内建命令：指定需要执行的bash内建命令。
+shell-builtin（可选）：要调用的bash内建命令。
 
-（可选）参数：传递给bash内建命令的参数。
+arg（可选）：传递给bash内建命令的一到多个参数。
 
-###  提示
+## 返回值
 
-**同名情况下的优先级顺序**
+返回该内建命令执行的返回值，除非传递的不是bash内建命令或该内建命令被禁用。
+
+## 例子
+
+同名情况下的优先级顺序：
 
 builtin 内建命令 > 函数 > 内建命令 > 外部命令
 
 ```shell
-#!/bin/bash
-#此时内建命令优先使用
+# 关于外部命令优先级最高的情况请参考enable命令。
+# 此时内建命令优先使用
 echo "the Great Wall"
-#调用内建命令type，显示命令的类型
+# 调用内建命令type，返回命令的类型（builtin）

+# 定义 echo 函数
 echo(){
     printf "123\n"
 }
-#此时同名函数优先使用
+# 此时同名函数优先使用，显示（123）

-type(选项)(参数)
+-a：在环境变量PATH中查找并显示所有包含name的可执行文件路径；当'-p'选项没有同时给出时，如果在别名、关键字，函数，内建的信息中存在name，则一并显示。
+-f：排除对shell函数的查找。
+-p：如果name在执行'type -t name'返回的不是'file'，那么什么也不返回；否则会在环境变量PATH中查找并返回可执行文件路径。
+-P：即使要查找的name是别名、内建、函数中的一个，仍然会在环境变量PATH中查找并返回可执行文件路径。
+-t：根据name的类型返回一个单词（别名，关键字，函数，内建，文件），否则返回空值。

-- 当您定义（修改）别名的值的时候，由于值的字符串有空格但您没有用 **单引号扩起整个值** ，例子如下。
+- 要显示的别名未定义。
+
+- 当您定义（修改）别名的值的时候，由于值的字符串有空格但您没有用**单引号扩起**，那么会导致严重的问题：
 
 ```shell
-#为方便演示，删除全部别名
+# 为方便演示，删除全部别名
 unalias -a
+# 没有用单引号扩起
 alias rm=rm -rf
-#执行命令后报错 bash: alias: -rf: not found
-#这时使用alias查看全部时结果返回 alias rm='rm'
+# 执行命令后报错 bash: alias: -rf: not found
+# 这时使用alias查看rm的别名时返回 alias rm='rm'
 ```
 
 ```shell
-#更具有迷惑性的例子
-#为方便演示，删除全部别名
+# 更具有迷惑性的例子
+# 为方便演示，删除全部别名
 unalias -a
+# 仍然没有用单引号括起
 alias ls=ls --color=never
-#命令运行的结果看起来没有报错
+# 执行命令后看起来没有报错
 
-#使用alias查看全部别名会发现运行结果如下
-#alias --color=never

-Q&A
-
-Q：如何删除别名？
-
-A：请查看 `unalias` 命令。
+## Q&A
 
 Q：如果我要显示一到多个别名，但不知道其中是否有未定义的该怎么办？
 
 A：正常执行就是了，alias不会因为有一个未定义的别名就结束对剩余参数的执行。
 
-Q：如果我这么定义 `alias cd='ls' ls='cd'` ，会有什么后果？
+Q：如果我这么定义`alias cd='ls' ls='cd'`，会有什么后果？
 
-A：运行cd依然会切换目录，运行ls依然会列出文件夹的内容；不要这样定义；
+A：运行cd依然会切换目录，运行ls依然会列出文件夹的内容；不要这样定义。
 
 
 ### 注意
 
-1. ***请不要用这个命令对包括你自己在内的任何人开恶意的玩笑，原因如下：***
+1. **执行脚本时请注意：**
 
-> 如果终端环境中存在别名，那么在其中使用 `source` 命令调用bash脚本会出现以下行为：当执行的命令存在别名时，会按照别名的值调用执行；
+> 使用`source`命令执行的bash脚本如果执行了`alias`或`unalias`命令，那么有可能会对终端环境的别名设置产生影响；终端环境的别名设置也可能改变运行结果；
 >
-> 通过 `sh` 方式调用的bash脚本或直接运行当前用户有执行权限的脚本不受终端环境的别名影响。
+> 通过`sh`方式调用的bash脚本或直接运行当前用户有执行权限的脚本不受终端环境的别名影响。
+
+2. 删除别名，请查看`unalias`命令。
 
-2. 建议您不要对 `mv cp rm` 等命令的别名设置危险的 `-f` 选项。

-**date命令** 是显示或设置系统时间与日期。
+```shell
+date [OPTION]... [+FORMAT]
+date [-u|--utc|--universal] [MMDDhhmm[[CC]YY][.ss]]
+```
 
-很多shell脚本里面需要打印不同格式的时间或日期，以及要根据时间和日期执行操作。延时通常用于脚本执行过程中提供一段等待的时间。日期可以以多种格式去打印，也可以使用命令设置固定的格式。在类UNIX系统中，日期被存储为一个整数，其大小为自世界标准时间（UTC）1970年1月1日0时0分0秒起流逝的秒数。
+## 主要用途
 
-###  语法 
+- 转换时间到选定的格式，默认为当前。
+- 设置系统时间。
 
-```shell
-date(选项)(参数)
-```
+## 参数
 
-###  选项 
+format：输出的时间格式。

+%:::z   数值化时区格式，相比上一个格式增加':'以显示必要的精度（例如，-04，+05:30）
+%Z      时区缩写（如EDT）
+
+默认情况下，日期用零填充数字字段；以下可选的符号可以跟在'%'后面:
+
+-      (连字符) 不要填充相应的字段。
+_      (下划线) 使用空格填充相应的字段。
+0      (数字0) 使用数字0填充相应的字段。
++      用数字0填充，未来年份大于4位数字则在前面加上'+'号。
+^      允许的情况下使用大写。
+#      允许的情况下将默认的大写转换为小写，默认的小写转换为大写。

-有时需要检查一组命令花费的时间，举例：
-
-```shell
-#!/bin/bash
 
+# 有时需要检查一组命令花费的时间：
 start=$(date +%s)
 nmap wangchujiang.com &> /dev/null
-
 end=$(date +%s)
 difference=$(( end - start ))
+# 显示执行时间
 echo $difference seconds.
-```
 
-当你考虑输出带有时间的字符串时，例如（Current time: 2019/05/19）：
-
-最常用的方法：
-
-```shell
+# 当你考虑输出带有时间的字符串时，例如（Current time: 2019/05/19）：
+# 通常使用的方法：
 echo "Current time: $(date +"%Y/%m/%d")"
-```
-
-另一种方法：
-```shell
+# 另一种方法：
 suffix='Current time:'
-#和echo的用法差不多，注意如果换成单引号就不能替换变量了。
+# 注意如果换成单引号就不能替换变量了。
 date +"${suffix} %Y/%m/%d"
 ```
 
+### 注意
+
+1. 该命令是`GNU coreutils`包中的命令，相关的帮助信息请查看`man -s 1 date`或`info coreutils 'date invocation'`。

 ## 补充说明
 
-**sed** 是一种流编辑器，它是文本处理中非常中的工具，能够完美的配合正则表达式使用，功能不同凡响。处理时，把当前处理的行存储在临时缓冲区中，称为“模式空间”（pattern space），接着用sed命令处理缓冲区中的内容，处理完成后，把缓冲区的内容送往屏幕。接着处理下一行，这样不断重复，直到文件末尾。文件内容并没有 改变，除非你使用重定向存储输出。Sed主要用来自动编辑一个或多个文件；简化对文件的反复操作；编写转换程序等。

 cat
 ===
 
-连接文件并打印到标准输出设备上
+连接多个文件并打印到标准输出。
 
-## 补充说明
+## 概要
 
-**cat命令** 连接文件并打印到标准输出设备上，cat经常用来显示文件的内容，类似于下的type命令。
+```shell
+cat [OPTION]... [FILE]...
+```
 
-注意：当文件较大时，文本在屏幕上迅速闪过（滚屏），用户往往看不清所显示的内容。因此，一般用more等命令分屏显示。为了控制滚屏，可以按Ctrl+S键，停止滚屏；按Ctrl+Q键可以恢复滚屏。按Ctrl+C（中断）键可以终止该命令的执行，并且返回Shell提示符状态。
+## 主要用途
 
-###  语法 
+- 显示文件内容，如果没有文件或文件为`-`则读取标准输入。
+- 将多个文件的内容进行连接并打印到标准输出。
+- 显示文件内容中的不可见字符（控制字符、换行符、制表符等）。
 
-```shell
-cat(选项)(参数)
-```
+## 参数
+
+FILE（可选）：要处理的文件，可以为一或多个。
 
-###  选项 
+## 选项 
 
 ```shell
--n或--number：从1开始对所有输出的行数编号；
--b或--number-nonblank：和-n相似，只不过对于空白行不编号；
--s或--squeeze-blank：当遇到有连续两行以上的空白行，就代换为一行的空白行；
--A：显示不可打印字符，行尾显示“$”；
--e：等价于"-vE"选项；
--t：等价于"-vT"选项；
-```
+长选项与短选项等价
 
-###  参数 
+-A, --show-all           等价于"-vET"组合选项。
+-b, --number-nonblank    只对非空行编号，从1开始编号，覆盖"-n"选项。
+-e                       等价于"-vE"组合选项。
+-E, --show-ends          在每行的结尾显示'$'字符。
+-n, --number             对所有行编号，从1开始编号。
+-s, --squeeze-blank      压缩连续的空行到一行。
+-t                       等价于"-vT"组合选项。
+-T, --show-tabs          使用"^I"表示TAB（制表符）。
+-u                       POSIX兼容性选项，无意义。
+-v, --show-nonprinting   使用"^"和"M-"符号显示控制字符，除了LFD（line feed，即换行符'\n'）和TAB（制表符）。
 
-文件列表：指定要连接的文件列表。
+--help                   显示帮助信息并退出。
+--version                显示版本信息并退出。
+```
+
+## 返回值
 
-###  实例 
+返回状态为成功除非给出了非法选项或非法参数。
 
-设m1和m2是当前目录下的两个文件
+## 例子 
 
 ```shell
-cat m1 （在屏幕上显示文件m1的内容）
-cat m1 m2 （同时显示文件m1和m2的内容）
-cat m1 m2 > file （将文件m1和m2合并后放入文件file中）
+# 合并显示多个文件
+cat ./1.log ./2.log ./3.log
+# 显示文件中的非打印字符、tab、换行符
+cat -A test.log
+# 压缩文件的空行
+cat -s test.log
+# 显示文件并在所有行开头附加行号
+cat -n test.log
+# 显示文件并在所有非空行开头附加行号
+cat -b test.log
+# 将标准输入的内容和文件内容一并显示
+echo '######' |cat - test.log
 ```
 
+### 注意
+
+1. 该命令是`GNU coreutils`包中的命令，相关的帮助信息请查看`man -s 1 cat`或`info coreutils 'cat invocation'`。
+2. 当使用`cat`命令查看**体积较大的文件**时，文本在屏幕上迅速闪过（滚屏），用户往往看不清所显示的内容，为了控制滚屏，可以按`Ctrl+s`键停止滚屏；按`Ctrl+q`键恢复滚屏；按`Ctrl+c`（中断）键可以终止该命令的执行，返回Shell提示符状态。
+3. 建议您查看**体积较大的文件**时使用`less`、`more`命令或`emacs`、`vi`等文本编辑器。

 tee
 ===
 
-把数据重定向到给定文件和屏幕上
+从标准输入读取数据并重定向到标准输出和文件。
 
-## 补充说明
+## 概要
 
-**tee命令** 用于将数据重定向到文件，另一方面还可以提供一份重定向数据的副本作为后续命令的stdin。简单的说就是把数据重定向到给定文件和屏幕上。
+```shell
+tee [OPTION]... [FILE]...
+```
 
-存在缓存机制，每1024个字节将输出一次。若从管道接收输入数据，应该是缓冲区满，才将数据转存到指定的文件中。若文件内容不到1024个字节，则接收完从标准输入设备读入的数据后，将刷新一次缓冲区，并转存数据到指定文件。
+## 主要用途
 
-###  语法
+- 需要同时查看数据内容并输出到文件时使用。
 
-```shell
-tee(选项)(参数)
-```
+## 参数
+
+FILE（可选）：要输出的文件，可以为一或多个。
 
-###  选项
+## 选项 
 
 ```shell
--a：向文件中重定向时使用追加模式；
--i：忽略中断（interrupt）信号。
-```
+长选项与短选项等价
 
-###  参数
+-a, --append               追加到文件中而不是覆盖。
+-i, --ignore-interrupts    忽略中断信号（Ctrl+c中断操作无效）。
+-p                         诊断写入非管道的错误。
+--output-error[=MODE]      设置写错误时的行为，请查看下方的MODE部分。
+--help                     显示帮助信息并退出。
+--version                  显示版本信息并退出。
 
-文件：指定输出重定向的文件。
+MODE决定了当出现写错误时的输出行为，可用的MODE如下：
 
-在终端打印stdout同时重定向到文件中：
+'warn'           当写入到任何输出报错时诊断。
+'warn-nopipe'    当写入到任何输出（而不是管道）报错时诊断。
+'exit'           当写入到任何输出报错时退出。
+'exit-nopipe'    当写入到任何输出（而不是管道）报错时退出。
 
-```shell
-ls | tee out.txt
-1.sh
-1.txt
-2.txt
-eee.tst
-EEE.tst
-one
-out.txt
-string2
-www.pdf
-WWW.pdf
-WWW.pef
+-p选项的指定的默认MODE为'warn-nopipe'。
+当'--output-error'没有在选项中时，默认的操作是当写入到管道报错时立刻退出，诊断错误信息并写入到非管道输出。
 ```
 
+## 返回值
+
+返回状态为成功除非给出了非法选项或非法参数。
+
+## 例子 
+
 ```shell
-[root@localhost text]# ls | tee out.txt | cat -n
-     1  1.sh
-     2  1.txt
-     3  2.txt
-     4  eee.tst
-     5  EEE.tst
-     6  one
-     7  out.txt
-     8  string2
-     9  www.pdf
-    10  WWW.pdf
-    11  WWW.pef
+# 将进程信息通过管道输出到标准输出（终端）并覆盖写入到文件中。
+ps -ef |tee info_a.log info_b.log
+
+# 将进程信息通过管道输出到标准输出（终端）并追加写入到文件中。
+ps -ef |tee -a info_a.log info_b.log
 ```
 
+### 注意
+
+1. 该命令是`GNU coreutils`包中的命令，相关的帮助信息请查看`man -s 1 tee`或`info coreutils 'tee invocation'`。
+2. 存在缓存机制，每1024个字节将输出一次。若从管道接收输入数据，应该是缓冲区满，才将数据转存到指定的文件中。若文件内容不到1024个字节，则接收从标准输入设备读入的数据后，将刷新一次缓冲区，并转存数据到指定文件。

+mapfile
+===
+
+从标准输入读取行并赋值到数组。
+
+## 概要
+
+```shell
+mapfile [-d delim] [-n count] [-O origin] [-s count] [-t] [-u fd] [-C callback] [-c quantum] [array]
+```
+
+## 主要用途
+
+- 从标准输入或文件描述符读取行并赋值到数组。
+
+
+## 选项
+
+```shell
+-d delim       将delim设为行分隔符，代替默认的换行符。
+-n count       从标准输入中获取最多count行，如果count为零那么获取全部。
+-O origin      从数组下标为origin的位置开始赋值，默认的下标为0。
+-s count       跳过对前count行的读取。
+-t             读取时移除行分隔符delim（默认为换行符）。
+-u fd          从文件描述符fd中读取。
+-C callback    每当读取了quantum行时，调用callback语句。
+-c quantum     设定读取的行数为quantum。
+
+如果使用-C时没有同时使用-c指定quantum的值，那么quantum默认为5000。
+当callback语句执行时，将数组下一个要赋值的下标以及读取的行作为额外的参数传递给callback语句。
+如果使用-O时没有提供起始位置，那么mapfile会在实际赋值之前清空该数组。
+```
+
+## 参数
+
+array（可选）：用于输出的数组名称。如果没有指定数组名称，那么会默认写入到变量名为MAPFILE的数组中。
+
+## 返回值
+
+返回成功除非使用了非法选项、指定的数组是只读的、指定的数组不是下标数组。
+
+## 例子
+
+```shell
+# 常见的读取形式。
+mapfile < source_file target_array
+cat source_file |mapfile target_array
+mapfile -u fd target_array
+
+# 只读取前5行。
+mapfile < source_file -n 5 target_array
+
+# 跳过前5行。
+mapfile < source_file -s 5 target_array
+
+# 在数组指定的下标开始赋值。
+# 请注意：这样做不会清空该数组。
+mapfile < source_file -O 2 target_array
+
+# 读取时设定行分隔符为tab。
+# 注意，第二行的tab在终端需要用ctrl+v tab输入；
+mapfile < source_file -d $'\t' target_array
+mapfile < source_file -d '	' target_array
+
+# 读取时移除行分隔符（tab）。
+mapfile < source_file -d $'\t' -t target_array
+# 读取时移除行分隔符（换行符）。
+mapfile < source_file -t target_array
+
+# 每读取2行，执行一次语句（在这里是echo）。
+mapfile < source_file -C "echo CALLBACK:" -c 2 target_array
+
+# 遍历下标，依次显示数组的元素。
+for i in ${!target_array[@]}; do
+  printf "%s" ${target_array[i]}
+done
+```
+
+### 注意
+
+1. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。
+2. bash内建命令readarray是mapfile的同义词。

+suspend
+===
+
+挂起shell的执行。
+
+## 概要
+
+```shell
+suspend [-f]
+```
+
+## 主要用途
+
+- 挂起shell的执行，直到收到`SIGCONT`信号。
+
+- 除非使用`-f`选项，否则无法对`login shell`使用。
+
+
+## 选项
+
+```shell
+-f    对login shell执行挂起操作。
+```
+
+## 返回值
+
+返回成功除非未开启作业控制或发生了错误。
+
+## 例子
+
+```shell
+# 打开一个终端，首先获取PID。
+echo $$
+# 执行挂起命令
+suspend
+```
+
+```shell
+# 再打开一个终端，发送SIGCONT命令
+kill -s SIGCONT PID
+# 此时之前的终端结束挂起状态，可以正常交互。
+```
+
+### 注意

 fg
 ===
 
-将后台作业放到前台终端运行
+将后台作业移动到前台终端运行
 
-## 补充说明
+## 概要
 
-**fg命令** 用于将后台作业（在后台运行的或者在后台挂起的作业）放到前台终端运行。与bg命令一样，若后台任务中只有一个，则使用该命令时，可以省略任务号。
+```shell
+fg [job_spec ...]
+```
 
-在Linux系统中执行某些操作时候，有时需要将当前任务暂停调至后台，或有时须将后台暂停的任务重启开启并调至前台，这一序列的操作将会使用到 jobs、bg、和 fg 三个命令以及两个快捷键来完成。
+## 主要用途
 
-###  语法
+- 用于将后台作业（在后台运行的或者在后台挂起的作业）放到前台终端运行。
 
-```shell
-fg(参数)
-```
+- 若后台任务中只有一个，则使用该命令时可以省略任务号。
+
+## 参数
 
-###  参数
+job_spec（可选）：指定要移动到前台执行的作业标识符，可以是一到多个。
 
-作业标识：指定要放到前台的作业标识号。
+## 返回值
 
-###  实例
+返回作业的执行状态，如果发生了错误返回失败。
 
-使用fg命令将任务号为1的任务从后台执行转换到前台执行，输入如下命令：
+## 例子
 
 ```shell
-fg 1          #将任务转换到前台执行
-```
+# 运行sleep命令，然后按下ctrl+z。
+sleep 60
+^Z
+[1]+  Stopped                 sleep 60
 
-执行上面的命令后，命令行窗口将显示如下信息：
+# 使用fg命令使得作业在前台运行。
+fg %1
 
-```shell
-find / -name password       #前台执行命令
+# 返回信息：
+sleep 60
 ```
 
+### 注意
+
+1. `bash`的作业控制命令包括`bg fg kill wait disown suspend`。
+2. 该命令需要`set`选项`monitor`处于开启状态时才能执行；查看作业控制状态：输入`set -o`查看`monitor`行；执行`set -o monitor`或`set -m`开启该选项。
+3. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。

-显示Linux中的任务列表及任务状态
+显示作业的状态。
 
-## 补充说明
+## 概要
 
-**jobs命令** 用于显示Linux中的任务列表及任务状态，包括后台运行的任务。该命令可以显示任务号及其对应的进程号。其中，任务号是以普通用户的角度进行的，而进程号则是从系统管理员的角度来看的。一个任务可以对应于一个或者多个进程号。
+```shell
+jobs [-lnprs] [jobspec ...]
+jobs -x command [args]
+```
 
-在Linux系统中执行某些操作时候，有时需要将当前任务暂停调至后台，或有时须将后台暂停的任务重启开启并调至前台，这一序列的操作将会使用到 jobs、bg、和 fg 三个命令以及两个快捷键来完成。
+## 主要用途
 
-###  语法
+- 显示作业的状态。
+- 列出活动的作业。
+- 列出停止的作业。
+
+## 选项
 
 ```shell
-jobs(选项)(参数)
+-l	在作业信息中额外的列出PID。
+-n	只列出最近一次通知以来状态变更的作业。
+-p	只列出PID。
+-r	只输出处于运行状态的作业。
+-s	只输出处于停止状态的作业。
 ```
 
-###  选项
+## 返回值
+
+返回状态为成功除非给出了非法选项、执行出现错误。
+
+如果使用`jobs -x command [args]`形式执行，那么返回值为`command`的退出状态。
+
+## 例子
 
 ```shell
--l：显示进程号；
--p：仅任务对应的显示进程号；
--n：显示任务状态的变化；
--r：仅输出运行状态（running）的任务；
--s：仅输出停止状态（stoped）的任务。
-```

+[2]  13338 Running                 sleep 60 &
 
-使用jobs命令显示当前系统的任务列表，输入如下命令：
+[user2@pc] jobs -p
+12927
+13338
 
-```shell
-jobs -l               #显示当前系统的任务列表
-```
+[user2@pc] jobs -s
+[1]-  Stopped                 ssh 192.168.1.4
 
-上面的命令执行后，将显示出当前系统下的任务列表信息，具体如下所示：
+[user2@pc] jobs -r
+[2]   Running                 sleep 60 &
 
-```shell
-[1] + 1903 运行中          find / -name password &
-```
+[user2@pc] kill -9 12927
+[2]   Done                    sleep 60
+
+[user2@pc] jobs -n -l
+[1]+ 12927 Killed             ssh 192.168.1.4
 
-注意：要得到以上输出信息，必须在执行jobs命令之前执行命令`find / -name password &`。否则，执行jobs命令不会显示任何信息。
+[user2@pc] jobs -n -l
+```
 
-其中，输出信息的第一列表示任务编号，第二列表示任务所对应的进程号，第三列表示任务的运行状态，第四列表示启动任务的命令。
+### 注意
 
+1. `bash`的作业控制命令包括`bg fg kill wait disown suspend`。
+2. 该命令需要`set`选项`monitor`处于开启状态时才能执行；查看作业控制状态：输入`set -o`查看`monitor`行；执行`set -o monitor`或`set -m`开启该选项。
+3. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。

+
+## 主要用途
+
+- 从当前shell的作业列表中移除全部作业。
+
+- 从当前shell的作业列表中移除指定的一到多个作业。
+
+- 从当前shell的作业列表中移除正在运行的作业。
+
+- 标记作业，使得它们在当前shell退出后也不会结束。
+
+
+## 选项
+
+```shell
+-h    标记每个作业标识符，这些作业将不会在shell接收到sighup信号时接收到sighup信号。
+-a    移除所有的作业。
+-r    移除运行的作业。
+```
+
+## 参数
+
+jobspec（可选）：要移除的作业标识符，可以是一到多个。
+
+pid（可选）：要移除的作业对应的进程ID，可以是一到多个。
+
+
+## 返回值
+
+返回成功除非未开启作业控制或执行出现错误。
+
+## 例子
+
+```shell
+# 演示。
+[user2@pc] ssh 192.168.1.4
+user2@192.168.1.4's password:
+# 此时按下ctrl+z使得交互停止。

+[1] 109080
+
+[user2@pc] jobs -l
+[1]+ 109080 Running                 sleep 90 &
+
+[user2@pc] disown -h %1
+
+[user2@pc] exit
+
+# 此时前一个终端已经关闭，现在打开新终端查找该作业。
+[user2@pc] pgrep -a -u user2 -f 'sleep 90'
+109080 sleep 90
+```
+
+### 注意
+
+1. `bash`的作业控制命令包括`bg fg kill wait disown suspend`。
+2. 该命令需要`set`选项`monitor`处于开启状态时才能执行；查看作业控制状态：输入`set -o`查看`monitor`行；执行`set -o monitor`或`set -m`开启该选项。
+3. 该命令是bash内建命令，相关的帮助信息请查看`help`命令。

-**nl命令** 读取 file 参数（缺省情况下标准输入），计算输入中的行号，将计算过的行号写入标准输出。在输出中，nl命令根据您在命令行中指定的标志来计算左边的行。输入文本必须写在逻辑页中。每个逻辑页有头、主体和页脚节（可以有空节）。除非使用`-p`选项，nl 命令在每个逻辑页开始的地方重新设置行号。可以单独为头、主体和页脚节设置行计算标志（例如，头和页脚行可以被计算然而文本行不能）。其默认的结果与`cat -n`有点不太一样， nl 可以将行号做比较多的显示设计，包括位数与是否自动补齐0等等的功能。
-
-###  语法
+## 概要
 
 ```shell
-nl (选项) (参数)
+nl [OPTION]... [FILE]...
 ```
 
-###  选项
+## 主要用途
+
+- 将每一个输入的文件添加行号后发送到标准输出。
+- 当没有文件或文件为`-`时，读取标准输入
+- 处理逻辑页（logical page）。
+
+## 选项
 
 ```shell
--b ：指定行号指定的方式，主要有两种：
-    -b a ：表示不论是否为空行，也同样列出行号(类似 cat -n)；
-    -b t ：如果有空行，空的那一行不要列出行号(默认值)；
+-b, --body-numbering=STYLE           使用STYLE 为body部分的行附加行号。
+-d, --section-delimiter=CC           使用CC作为logical page的分隔符。
+-f, --footer-numbering=STYLE         使用STYLE 为footer部分的行附加行号。
+-h, --header-numbering=STYLE         使用STYLE 为header部分的行附加行号。
+-i, --line-increment=NUMBER          行号递增间隔为NUMBER。
+-l, --join-blank-lines=NUMBER        连续NUMBER行的空行作为一行处理。
+-n, --number-format=FORMAT           根据FORMAT插入行号。
+-p, --no-renumber                    不要在每个部分重置行号。
+-s, --number-separator=STRING        在行号后添加字符串STRING。
+-v, --starting-line-number=NUMBER    每部分的起始行号。
+-w, --number-width=NUMBER            行号宽度为NUMBER。
+--help                               显示帮助信息并退出。
+--version                            显示版本信息并退出。
 
--n ：列出行号表示的方法，主要有三种：
-    -n ln ：行号在萤幕的最左方显示；
-    -n rn ：行号在自己栏位的最右方显示，且不加 0 ；
-    -n rz ：行号在自己栏位的最右方显示，且加 0 ；
 
--w ：行号栏位的占用的位数。
--p ：在逻辑定界符处不重新开始计算。
-```
+默认选项为：-bt -d'\:' -fn -hn -i1 -l1 -nrn -sTAB -v1 -w6
 
-###  实例
+CC是由两个字符组成的，默认为\: ,第二个字符如果缺失则默认为:
 
- **用 nl 列出 log2015.log 的内容** ：
+STYLE可以为下列可用值之一：
 
-```shell
-root@localhost [test]# nl log2015.log
-1 2015-01
-2 2015-02
+a       所有行标记行号。
+t       仅为非空行标记行号。
+n       不标记行号。
+pBRE    符合基础正则表达式（BRE）的行会标记行号。
+
+FORMAT可以为下列可用值之一：
 
-3 ======[root@localhost test]#
+ln    左对齐，不会在开始部分补充0以满足宽度。
+rn    右对齐，不会在开始部分补充0以满足宽度。
+rz    右对齐，会在开始部分补充0以满足宽度。
+
+logical page
+三部分组成（header， body， footer）
+起始标记（header \:\:\:， body \:\:， footer \:）
 ```
 
-说明：文件中的空白行，nl 不会加上行号
+## 参数
+
+FILE（可选）：要处理的文件，可以为一或多个。
 
- **用 nl 列出 log2015.log 的内容，空本行也加上行号** ：
+## 返回值
+
+返回0表示成功，返回非0值表示失败。
+
+## 例子
+
+```shell
+nl_logicalpage.txt：该文件用于说明nl命令处理逻辑页，内容如下：
+\:\:\:
+header_1
+\:\:
+body_1
+\:
+footer_1
+\:\:\:
+header_2
+\:\:
+body_2
+\:
+footer_2
+```
 
 ```shell
-[root@localhost test]# nl -b a log2015.log
-1 2015-01
-2 2015-02
-3
-4
-5 ======[root@localhost test]#

+
+     1	body_1
+
+       footer_1
+
+       header_2
+
+     1	body_2
+
+       footer_2
+
+[user2@pc ~]$ nl -v0 -fa -ha nl_logicalpage.txt

 id
 ===
 
-显示用户的ID以及所属群组的ID
+打印真实以及有效的用户和所在组的信息
 
-## 补充说明
+## 概要
 
-**id命令** 可以显示真实有效的用户ID(UID)和组ID(GID)。UID 是对一个用户的单一身份标识。组ID（GID）则对应多个UID。id命令已经默认预装在大多数Linux系统中。要使用它，只需要在你的控制台输入id。不带选项输入id会显示如下。结果会使用活跃用户。
+```shell
+id [OPTION]... [USER]...
+```
+
+## 主要用途
 
-当我们想知道某个用户的UID和GID时id命令是非常有用的。一些程序可能需要UID/GID来运行。id使我们更加容易地找出用户的UID以GID而不必在`/etc/group`文件中搜寻。如往常一样，你可以在控制台输入`man id`进入id的手册页来获取更多的详情。
+- 没有选项时，打印指定用户ID信息。
 
-###  语法
+## 选项
 
 ```shell
-id [-gGnru]--[help][--version][用户名称]
+-a               兼容性选项，没有实际作用。
+-Z, --context    只打印进程的安全上下文。
+-g, --group      只打印有效的组ID。
+-G, --groups     打印全部组ID。
+-u, --user       只打印有效的用户ID。
+-z, --zero       使用空字符代替默认的空格来分隔条目。
+--help           显示帮助信息并退出。
+--version        显示版本信息并退出。
 ```
 
-###  选项
-
+只有在使用 `-u` `-g` `-G` 选项中一到多个时，以下选项可以使用：
 ```shell
--g或--group 　 显示用户所属群组的ID。
--G或--groups   显示用户所属附加群组的ID。
--n或--name 　  显示用户，所属群组或附加群组的名称。
--r或--real 　  显示实际ID。
--u或--user 　  显示用户ID。
--help 　       显示帮助。
--version 　    显示版本信息。
+-n, --name    打印名称而不是数字。
+-r, --real    打印真实ID而不是有效ID。
 ```
 
-###  实例
+## 参数
+user（可选）：可以为一到多个，默认为当前用户。
+
+## 返回值
+
+返回0表示成功，返回非0值表示失败。

 trap
 ===
 
-指定在接收到信号后将要采取的动作
+捕捉信号和其他事件并执行命令。
 
-## 补充说明
-
-**trap命令** 用于指定在接收到信号后将要采取的动作，常见的用途是在脚本程序被中断时完成清理工作。当shell接收到sigspec指定的信号时，arg参数（命令）将会被读取，并被执行。例如：
+## 概要
 
 ```shell
-trap "exit 1" HUP INT PIPE QUIT TERM
+trap [-lp] [[arg] signal_spec ...]
 ```
 
-表示当shell收到HUP INT PIPE QUIT TERM这几个命令时，当前执行的程序会读取参数“exit 1”，并将它作为命令执行。
+## 主要用途
+
+- 用于指定在接收到信号后将要采取的动作。
+- 脚本程序被中断时执行清理工作。
 
-###  语法
+## 选项
 
 ```shell
-trap -[lp] [[arg] sigspec ...]
+-l    打印信号名称以及信号名称对应的数字。
+-p    显示与每个信号关联的trap命令。
 ```
 
-###  选项参数说明
-
-如果arg参数缺省或者为“-”，每个接收到的sigspec信号都将会被重置为它们进入shell时的值；
-
-如果arg是空字符串每一个由sigspec指定的信号都会被shell和它所调用的命令忽略；
-
-如果有`-p`选项而没有提供arg参数则会打印所有与sigspec指定信号相关联的的trap命令；
-
-如果没有提供任何参数或者仅有-p选项，trap命令将会打印与每一个信号有关联的命令的列表；
-
-`-l`选项的作用是让shell打印一个命令名称和其相对应的编号的列表。
+## 参数
 
-每个sigspec信号都是是以名字或者编号的形式定义在signal.h头文件中，信号的名字是不区分大小写的，其前缀SIG是可选的，如果某个信号是 EXIT（0），那么arg指定的命令将会在shell上执行退出命令时执行（If a sigspec is EXIT (0) the command arg is executed on exit from the shell），如果sigspec是DEBUG，那么arg指定的命令将会在以下每个命令执行之前执行：
+arg：接收到信号时执行的命令。
+ 
+signal_spec：信号名称或信号名称对应的数字。
 
-简单命令，for语句，case语句，select命令，算法命令，在函数内的第一条命令。
+## 返回值
 
-更多trap debug的使用可以参考extdebug选项说明。
+如果表达式执行结果为成功时返回0，当参数 `signal_spec` 没有指定有效值时返回1。
 
-如果sigspec是ERR，arg参数指定的命令将会在任何简单命名执行完后返回值为非零值时执行，但是也有以下例外情况：
-
-1.  如果执行失败的命令是紧跟在while或者until关键字之后的一组命令中的一部分时
-2.  如果执行失败的命令是if测试语句的一部分时，是 && 和 ||连接的列表中的一部分时
-3.  如果执行失败的命令的返回值是被取反过的（通过!操作符）
-
-在以上情况中如果sigspec是ERR，arg命令不会执行，这些规则同样适用于errexit选项。如果sigspec是RETURN，arg指定的命令在每次shell函数或者脚本用"."或者内置的命令执行完成后执行，在shell入口处被忽略的命令 是没法被trap和reset的，被trap的信号，在创建的子进程中使用时会在子进程被创建时被重置为原始的值。如果trap使用的sigspec信号 是invalid的信号则trap命令返回false（失败），否则返回成功（true）。
-
-###  信号
+## 关于信号
 
 信号是一种进程间通信机制，它给应用程序提供一种异步的软件中断，使应用程序有机会接受其他程序活终端发送的命令(即信号)。应用程序收到信号后，有三种处理方式：忽略，默认，或捕捉。进程收到一个信号后，会检查对该信号的处理机制。如果是SIG_IGN，就忽略该信号；如果是SIG_DFT，则会采用系统默认的处理动作，通常是终止进程或忽略该信号；如果给该信号指定了一个处理函数(捕捉)，则会中断当前进程正在执行的任务，转而去执行该信号的处理函数，返回后再继续执行被中断的任务。
 
-在有些情况下，我们不希望自己的shell脚本在运行时刻被中断，比如说我们写得shell脚本设为某一用户的默认shell，使这一用户进入系统后只能作某一项工作，如数据库备份， 我们可不希望用户使用Ctrl c之类便进入到shell状态，做我们不希望做的事情。这便用到了信号处理。

-###  捕获信号
 
-当你按下 Ctrl + C 键或 Break 键在终端一个shell程序的执行过程中，正常程序将立即终止，并返回命令提示符。这可能并不总是可取的。例如，你可能最终留下了一堆临时文件，将不会清理。
+## 例子
 
-捕获这些信号是很容易的，trap命令的语法如下：
+当shell收到 `HUP INT PIPE QUIT TERM` 这几个命令时，当前执行的程序会执行 `exit 1`。
 
 ```shell
-$ trap commands signals
+[root@pc root]$ trap "exit 1" HUP INT PIPE QUIT TERM
 ```
 
-这里的命令可以是任何有效的Linux命令，或一个用户定义的函数，信号可以是任意数量的信号，你想来捕获的列表。

-在shell脚本中的陷阱有三种常见的用途：

-1.  清理临时文件
-2.  忽略信号
-
- **1、清理临时文件：** 
-
-trap命令作为一个例子，下面展示了如何可以删除一些文件，然后退出，如果有人试图从终端中止程序：
+下面展示了如果有人试图从终端中止程序时，如何删除文件然后退出：
 
 ```shell
-trap "rm -f $WORKDIR/work1$ $WORKDIR/dataout$; exit" 2
+trap "rm -f $WORKDIR/work1 $WORKDIR/dataout; exit" 2
 ```
 
-执行shell程序，这个陷阱的角度，这两个文件work1$$ 和 dataout$$将被自动删除，如果程序接收信号数为2。
-
-因此，用户中断执行，如果执行的程序后，这个陷阱你可以放心，这两个文件将被清理。 exit 命令如下 rm 是必要的，因为没有它的执行将继续在节目中的一点，它离开时收到信号。
+执行shell程序，如果程序接收信号为2，那么这两个文件 （work1 和 dataout） 将被自动删除。
 
-1号信号产生挂断：要么有人故意挂断线路或线路被意外断开。
-
-您可以修改前面的陷阱也删除指定的文件，在这种情况下，两个信号信号1号添加到列表：
-
-```shell
-$ trap "rm $WORKDIR/work1$ $WORKDIR/dataout$; exit" 1 2
-```
-
-现在，这些文件将被删除，如果该行被挂了，或者按Ctrl c键被按下。
-
-来捕获指定的命令必须用引号括起来，如果它们包含一个以上的命令。另外请注意，在 shell 命令行扫描 trap 命令得到执行，并再次当一个所列出的的信号被接收的时间。
-
-WORKDIR 值 $$ 所以在前面的例子中，将被取代 trap 命令执行的时间。如果你想这种替代发生在收到信号1或2的时间你可以把单引号内的命令：
+添加信号1 `SIGHUP`：
 
 ```shell
-$ trap 'rm $WORKDIR/work1$ $WORKDIR/dataout$; exit' 1 2
+$ trap "rm $WORKDIR/work1 $WORKDIR/dataout; exit" 1 2
 ```
 
- **2、忽略信号：** 
+### 2 忽略信号
 
-如果陷阱列出的命令是空的，指定的信号接收时，将被忽略。例如，下面的命令：
+如果陷阱列出的命令是空的，指定的信号接收时，将被忽略：
 
 ```shell
 $ trap '' 2
 ```
 
-指定的中断信号是被忽略的。你可能要忽略某些信号时进行一些操作，不希望打断。可以指定多个信号被忽略如下：
+忽略多个信号：
 
 ```shell
 $ trap '' 1 2 3 15
 ```
 
-注意，第一个参数必须被指定为一个信号被忽略，而不是相当于写入下面的内容，它具有独立的含义也各有：
 
-```shell
-$ trap  2
-```
-
-如果你忽略了一个信号，所有的子shell也忽略该信号。不过，如果指定要采取的行动在收到的信号，所有的子shell仍然会在收到该信号的默认操作。
+### 3 重置陷阱
 
- **3、重设陷阱：** 
-
-当你改变了默认在收到信号后应采取的动作，你可以改变它回来的陷阱，如果你只是省略第一个参数;
+当你改变了收到信号后采取的动作，你可以省略第一个参数来重置到默认行为。
 
 ```shell
 $ trap 1 2
 ```
 
-复位应采取的动作收到信号1或2返回默认。
 
+### 注意
+
+1. `trap -l` 等价于执行 `kill -l`。
+2. 发送信号请查看 `kill` 命令。
+3. 该命令是bash内建命令，相关的帮助信息请查看 `help` 命令。
+4. 建议您阅读以下参考资料来深入了解该命令：

+
+**使用 curl 测试网站加载速度**
+
+命令有一个鲜为人知的选项，`-w`，该选项在请求结束之后打印本次请求的统计数据到标准输出。
+
+首先，我们定义控制打印行为的格式化字符串。新建文本文件 `fmt.txt`，并填入下面的内容：
+
+```ruby
+\n
+Response Time for: %{url_effective}\n\n
+DNS Lookup Time:\t\t%{time_namelookup}s\n
+Redirection Time:\t\t%{time_redirect}s\n
+Connection Time:\t\t%{time_connect}s\n
+App Connection Time:\t\t%{time_appconnect}s\n
+Pre-transfer Time:\t\t%{time_pretransfer}s\n
+Start-transfer Time:\t\t%{time_starttransfer}s\n\n
+Total Time:\t\t\t%{time_total}s\n
+```
+
+curl 提供了很多置换变量，可以在格式化字符串中通过 `%{var}` 的形式使用。完整的变量列表可以在 `curl` 的 `manpage` 中查看。简单介绍一下我们使用的这几个变量：
+
+
+- `url_effective`: 执行完地址重定向之后的最终 URL；
+- `time_namelookup`: 从请求开始至完成名称解析所花的时间，单位为秒，下同；
+- `time_redirect`: 执行所有重定向所花的时间；
+- `time_connect`: 从请求开始至建立 TCP 连接所花的时间；
+- `time_appconnect`: 从请求开始至完成 SSL/SSH 握手所花的时间；
+- `time_pretransfer`: 从请求开始至服务器准备传送文件所花的时间，包含了传送协商时间；
+- `time_starttransfer`: 从请求开始至服务器准备传送第一个字节所花的时间；
+- `time_total`: 完整耗时。
+
+然后执行请求，通过 @filename 指定保存了格式化字符串的文件：
+
+```shell
+$ curl -L -s -w @fmt.txt -o /dev/null http://www.google.com
+```
+
+输出：
+
+```c
+Response Time for: http://www.google.co.jp/?gfe_rd=cr&dcr=0&ei=cjIaWpTkHeiQ8QfnxYzoBA
+
+DNS Lookup Time:        0.000038s
+Redirection Time:       0.207271s
+Connection Time:        0.000039s
+App Connection Time:    0.000039s
+Pre-transfer Time:      0.000067s
+Start-transfer Time:    0.260115s
+
+Total Time:             0.467691s

+## 开发使用
+
+可以通过 `npm` 安装 [`linux-command`](https://www.npmjs.com/package/linux-command) 包，包含所有命令的 markdown 文本，和一个[索引文件](dist/data.json)。
+
+```bash
+npm install linux-command
+```
+
+```js
+var comm = require("linux-command");
+console.log("---->", comm.ls);
+
+var alias = require("linux-command/command/alias.md");
+console.log("---->", alias); // markdown string
+```
+
+你也可以通过 CDN 来访问索引数据，和对应的命令详细内容，我将更新内容定期发布版本，提供大家使用，[UNPKG](https://unpkg.com/linux-command/) 带上版本号，将锁定版本访问，删除版本号请求数据，将会自动重定向最新版本。
+
+```shell
+# 命令索引 JSON 数据
+https://unpkg.com/linux-command/dist/data.json
+# 对应命令详情（Markdown）数据
+https://unpkg.com/linux-command/command/<命令名称>.md
+```
+

+jq
+===
+
+一个轻量级的和灵活的命令行JSON处理器
+
+## 补充说明
+
+jq是用于处理JSON输入，将给定过滤器应用于其JSON文本输入并在标准输出上将过滤器的结果生成为JSON的工具。
+
+最简单的过滤器是., 它将jq的输入未经修改地复制到其输出中（格式设置除外，但请注意，IEEE754在内部用于数字表示，这意味着所有含义）。
+
+## 语法
+
+```bash
+jq [options] <jq filter> [file...]
+jq [options] --args <jq filter> [strings...]
+jq [options] --jsonargs <jq filter> [JSON_TEXTS...]
+```
+
+## 选项
+
+```bash
+-c               紧凑而不是漂亮的输出;
+-n               使用`null`作为单个输入值;
+-e               根据输出设置退出状态代码;
+-s               将所有输入读取（吸取）到数组中；应用过滤器;
+-r               输出原始字符串，而不是JSON文本;
+-R               读取原始字符串，而不是JSON文本;
+-C               为JSON着色;
+-M               单色（不要为JSON着色）;
+-S               在输出上排序对象的键;
+--tab            使用制表符进行缩进;
+--arg a v        将变量$a设置为value<v>;
+--argjson a v    将变量$a设置为JSON value<v>;
+--slurpfile a f  将变量$a设置为从<f>读取的JSON文本数组;
+--rawfile a f    将变量$a设置为包含<f>内容的字符串;
+--args           其余参数是字符串参数，而不是文件;
+--jsonargs       其余的参数是JSON参数，而不是文件;
+--               终止参数处理;
+```
+
+## 例子
+
+`.`: 改变输入
+
+```bash
+$ echo '{ "foo": { "bar": { "baz": 123 } } }' | jq '.'
+{
+  "foo": {
+    "bar": {
+      "baz": 123
+    }
+  }
+}
+
+```
+
+`.foo, .foo.bar, .foo?`: 获取一个键的值
+
+```bash
+$ echo '{"foo": 42, "bar": "less interesting data"}' | jq '.foo'
+42
+```
+
+`.[], .[]?, .[2], .[10:15]`: 数组运算
+
+```bash
+$ echo '[{"name":"JSON", "good":true}, {"name":"XML", "good":false}]' | jq '.[1]'
+{
+  "name": "XML",
+  "good": false
+}
+
+```
+
+`[], {}`: 构造一个数组/对象
+
+```bash
+$ echo '{"user":"stedolan","titles":["JQ Primer", "More JQ"]}' | jq '{user, title: .titles[]}'
+
+{
+  "user": "stedolan",
+  "title": "JQ Primer"
+}
+{
+  "user": "stedolan",
+  "title": "More JQ"
+}
+
+```
+
+`length`: 计算一个值的长度
+
+```bash
+$ echo '[[1,2], "string", {"a":2}, null]' | jq '.[] | length'                                  
+2
+6
+1
+0
+
+```
+
+`keys`: 取出数组中的键
+
+```bash
+$ echo '{"abc": 1, "abcd": 2, "Foo": 3}' | jq 'keys'                                        
+[
+  "Foo",
+  "abc",
+  "abcd"
+]
+
+```
+
+`,`: 使用多个过滤器
+
+```bash
+$ echo '{ "foo": 42, "bar": "something else", "baz": true}' | jq '.foo, .bar' 
+42
+"something else"
+
+```
+
+`|`: 通过管道将一个过滤器的输出当做下一个过滤器的输入
+
+```bash
+$ echo '[{"name":"JSON", "good":true}, {"name":"XML", "good":false}]' | jq '.[] | .name'                                                 
+"JSON"
+"XML"
+
+```
+
+`select(foo)`: 如果foo返回true，则输入保持不变
+
+```bash
+$ echo '[1,5,3,0,7]' | jq 'map(select(. >= 2))'                                                    
+[
+  5,
+  3,
+  7
+]
+
+```
+
+`map(foo)`: 每个输入调用过滤器
+
+```bash
+$ echo '[1,2,3]' | jq 'map(.+1)'
+[
+  2,
+  3,
+  4
+]
+
+```
+
+`if-then-else-end`: 条件判断
+
+```bash
+ $ echo '2' | jq 'if . == 0 then "zero" elif . == 1 then "one" else "many" end'
+
+"many"
+
+```
+
+`\(foo)`: 在字符串中插入值并进行运算
+
+```bash
+$ echo '42' | jq '"The input was \(.), which is one less than \(.+1)"'          
+
+"The input was 42, which is one less than 43"
+
+```
+
+

 ## 补充说明
 
-**hostname命令** 用于显示和设置系统的主机名称。环境变量HOSTNAME也保存了当前的主机名。在使用hostname命令设置主机名后，系统并不会永久保存新的主机名，重新启动机器之后还是原来的主机名。如果需要永久修改主机名，需要同时修改`/etc/hosts`和`/etc/sysconfig/network`的相关内容。

 ## 补充说明
 
-**rename命令** 用字符串替换的方式批量改变文件名。
+rename命令存在两个版本用法上有所区别 
+
+```bash
+C语言版本, 支持通配符
+[常用通配符说明]
+?    表示一个任意字符
+*    表示一个或一串任意字符
+
+Perl版本, 支持正则表达式
+[常用正则表达式符号说明]
+^    匹配输入的开始位置
+$    匹配输入的结尾
+.    匹配除换行符外的任意字符
++    匹配前一个字符一次或多次 例如，"zo+"可以匹配"zoo",但不匹配"z"
+[a-z]    表示某个范围内的字符，例如，"[a-z]"匹配"a"与"z"之间的任何一个小写字母字符。
+[^m-z]    否定的字符区间。与不在指定区间内的字符匹配。
+```
+
+区分方法: `rename --version`
+
+如果返回结果中包含 **util-linux** , 说明是C语言版本, 反之是Perl版本
+```bash
+# Perl版本 | Ubuntu(18),Mint(20)默认的是Perl版本
+$ rename --version
+/usr/bin/rename using File::Rename version 1.10
+
+# C语言版本 | Centos(7)默认的是C语言版本
+$ rename --version
+rename，来自 util-linux 2.23.2
+```
+
 
 ###  语法
 
-```shell
-rename(参数)
+```bash
+# Perl版本
+rename [ -h|-m|-V ] [ -v ] [ -0 ] [ -n ] [ -f ] [ -d ] [ -e|-E perlexpr]*|perlexpr [ files ]
+
+# C语言版本
+rename [选项] 表达式 替换的字符 文件...
 ```
 
 ###  参数
 
-```shell
-原字符串：将文件名需要替换的字符串；
-目标字符串：将文件名中含有的原字符替换成目标字符串；
-文件：指定要改变文件名的文件列表。
-```
+```bash
+# Perl版本
+-v, --verbose
+        详细：成功重命名的文件的打印名称。
 
-###  实例
+-0, --null
+        从STDIN读取时，请使用\0作为记录分隔符
 
-将main1.c重命名为main.c
+-n, --nono
+        不执行任何操作：打印要重命名的文件名，但不重命名。
 
-```shell
-rename main1.c main.c main1.c
-```
+-f, --force
+        覆盖：允许覆盖现有文件
 
- **rename支持通配符** 
+--path, --fullpath
+        重命名完整路径：包括任何目录组件。默认
 
-```shell
-?  可替代单个字符
-*  可替代多个字符
-[charset]  可替代charset集中的任意单个字符
-```
+-d, --filename, --nopath, --nofullpath
+        不重命名目录：仅重命名路径的文件名部分
 
-文件夹中有这些文件foo1, ..., foo9, foo10, ..., foo278
+-h, --help
+        帮助：打印提要和选项。
+
+-m, --man
+        手册: 打印手册页.
+
+-V, --version
+        版本: 显示版本号.
+
+-e      表达: 作用于文件名的代码.
+
+        可以重复来构建代码（比如“perl-e”）。如果没有-e，则第一个参数用作代码。
+
+-E      语句：对文件名执行操作的代码，如-e，但终止于 ';'.
 
-如果使用`rename foo foo0 foo?`，会把foo1到foo9的文件重命名为foo01到foo09，重命名的文件只是有4个字符长度名称的文件，文件名中的foo被替换为foo0。
 
-如果使用`rename foo foo0 foo??`，foo01到foo99的所有文件都被重命名为foo001到foo099，只重命名5个字符长度名称的文件，文件名中的foo被替换为foo0。
+# C语言版本
+-v, --verbose
+        提供视觉反馈，其中重命名了哪些文件（如果有的话）
 
-如果使用`rename foo foo0 foo*`，foo001到foo278的所有文件都被重命名为foo0001到foo0278，所有以foo开头的文件都被重命名。
+-V, --version
+        显示版本信息并退出。
 
-如果使用`rename foo0 foo foo0[2]*`，从foo0200到foo0278的所有文件都被重命名为foo200到foo278，文件名中的foo0被替换为foo。
+-s, --symlink
+        在符号链接目标上执行重命名
 
- **rename支持正则表达式** 
+-h, --help
+        显示帮助文本并退出
+```
+
+###  实例
+
+---

+```bash
+$ rename -v "s/txt/log/g" 1.txt 2.txt
+1.txt renamed as 1.log
+2.txt renamed as 2.log
 ```
 
 修改文件的后缀
 
-```shell
+```bash
 rename "s//.html//.php/" *     # 把.html 后缀的改成 .php后缀
 ```
 
 批量添加文件后缀
 
-```shell
+```bash
 rename "s/$//.txt/" *  # 把所有的文件名都以txt结尾
 ```
 
 批量删除文件名

 ## 补充说明
 
-**hostname命令** 用于显示和设置系统的主机名称。环境变量HOSTNAME也保存了当前的主机名。在使用hostname命令设置主机名后，系统并不会永久保存新的主机名，重新启动机器之后还是原来的主机名。如果需要永久修改主机名，需要同时修改`/etc/hosts`和`/etc/sysconfig/network`的相关内容。(hostnamectl有效的解决了这个问题)

+script
+===
+
+记录终端会话的所有操作
+
+## 补充说明
+
+**script** 用于在终端会话中，记录用户的所有操作和命令的输出信息。简而言之，记录终端会话发生的一切信息，如同一台终端录像机。例如，用户在输入某条命令时，字符的键入和删除也都会被记录。用户在终端的所有操作、终端的回显等信息会被以 `raw` 格式存储在日志文件，称为终端数据文件。命令的时间信息会被单独以另一种结构储存为日志文件，称为时间日志文件。使用命令`exit`或者快捷键`Ctrl + D`停止记录。
+
+
+###  语法
+
+```shell
+script(选项)(参数)
+```
+
+###  选项
+
+```shell
+-a, --append              # 对终端会话的操作信息，以追加方式写入文件（保留原文件内容）
+-c, --command command     # 只运行 command 命令而不打开交互终端。相当于开启 script ，执行 command ，再退出 script
+                          # command 可以是任意能够在终端会话执行的命令
+-e, --return              # 返回子进程的退出状态码
+-f, --flush               # 每次终端的内容发生变动，立马写入日志文件
+--force                   # 允许默认输出终端数据文件为符号链接
+-o, --output-limit size   # 限制终端数据文件和时间日志文件的大小，当文件大小达到此限制就会退出子进程
+                          # size 的单位可以设置为：KiB(=1024)、KB(=1000)、MiB(1024*1024)、MB(=1000*1000)
+                          # 同理还支持 GiB TiB PiB EiB ZiB YiB GB TB PB EB ZB YB
+-q, --quiet               # 安静模式。启动和退出script命令不显示任何提示
+-t[file], --timing[=file] # 输出时间日志信息到标准错误(stderr)或者文件
+-V, --version             # 显示版本信息并退出
+-h, --help                # 显示帮助文本并退出
+```
+
+###  参数
+
+* 终端数据文件：设置存储终端数据信息的文件名称
+
+###  实例
+
+```shell
+script                             # 开启记录，默认会在当前目录创建名称为 typescript 的文件来保存终端数据文件
+script command.log                 # 开启记录，在当前目录创建名称为 command.log 的文件来保存终端数据文件
+script -t 2>time.file command.log  # 开启记录，在当前目录创建名称为 command.log 的文件来保存终端数据文件
+                                   # 在当前目录创建名称为 time.file 的文件来保存时间日志文件
+```
+
+ **以追加模式记录终端信息** 
+
+```shell
+zfb@localhost:~$ script -t 2>time.file -a -f command.log
+Script started, file is command.log
+zfb@localhost:~$ echo "hello, world"
+hello, world
+zfb@localhost:~$ echo $(date "+%Y-%m-%d %H:%M:%S")
+2020-12-23 20:48:46
+zfb@localhost:~$ echo "Bye"
+Bye
+zfb@localhost:~$ ls -al
+total 20
+drwxr-xr-x  2 zfb zfb 4096 Dec 23 20:48 .
+drwxr-xr-x 37 zfb zfb 4096 Dec 23 20:49 ..

+zfb@localhost:~$ exit
+Script done, file is command.log
+zfb@localhost:~$
+```
+
+然后，用户可以查看终端数据文件，使用方法如下  
+
+```shell
+zfb@localhost:~$ cat command.log
+Script started on 2020-12-23 20:48:25+08:00 [TERM="xterm-256color" TTY="/dev/pts/0" COLUMNS="75" LINES="30"]
+zfb@localhost:~$ echo "hello, world"
+hello, world
+zfb@localhost:~$ echo $(date "+%Y-%m-%d %H:%M:%S")
+2020-12-23 20:48:46
+zfb@localhost:~$ echo "Bye"
+Bye
+zfb@localhost:~$ ls -al
+total 20
+drwxr-xr-x  2 zfb zfb 4096 Dec 23 20:48 .
+drwxr-xr-x 37 zfb zfb 4096 Dec 23 20:49 ..

+zfb@localhost:~$ exit
+
+Script done on 2020-12-23 20:49:04+08:00 [COMMAND_EXIT_CODE="0"]
+zfb@localhost:~$
+```
+
+其中，只有命令`cat command.log`是用户输入，其他均为自动呈现。通过查看上面输出的时间`2020-12-23 20:48:46`，可以证明，这是重现的记录，而非重新执行一遍命令。也就是说，可以把`time.file`和`command.log`文件移动到任意一台机器上，都可以重现命令输入与终端回显。

+scriptreplay
+===
+
+重新播放终端会话的所有操作
+
+## 补充说明
+
+**scriptreplay** 用于在终端中，根据 `script` 命令记录的终端数据文件和时间日志文件，重现当时用户的所有操作和命令的输出信息。简而言之，重现播放当时终端会话发生的一切信息，而不是重新运行一遍命令。例如，用户当时在输入某条命令时，字符的键入和删除也都会被重现。非常适合用于教程演示场合。而且，在机器 A 上面使用 `script` 命令记录终端操作，可以在机器 B 上面使用 `scriptreplay` 命令重新播放。
+
+
+###  语法
+
+```shell
+scriptreplay [options] [-t] timingfile [typescript [divisor]]
+```
+
+###  选项
+
+```shell
+-t, --timing file         # 记录时间日志的文件名称
+-s, --typescript file     # 记录终端数据信息的日志文件名称
+-d, --divisor number      # 表示倍速播放，把时间日志文件记录的时间间隔都除以 number
+                          # -d 2 表示播放速度是原始输入单条命令的速度的两倍，-d 0.1 表示播放单条命令的速度减慢 10 倍
+-m, --maxdelay number     # 表示命令之间的最大延迟时间（单位是秒）
+                          # -m 2 表示 command.log 中存放的两条命令之间的间隔时间如果大于两秒，则按两秒执行播放
+-V, --version             # 显示版本信息并退出
+-h, --help                # 显示帮助文本并退出
+```
+
+###  参数
+
+* 时间日志文件：存储时间日志信息的文件名称
+* 终端数据文件：存储终端数据信息的文件名称
+
+###  实例
+
+```shell
+# 重新播放终端内容，默认第一个参数是时间日志，第二个参数是终端数据文件
+scriptreplay time.file command.log
+# 重新播放终端内容，播放快进速度为 1 ，命令之间最大延时为 2 秒
+scriptreplay -d 1 -m 2 -t time.file -s command.log
+```
+
+ **记录终端内容到文件** 
+
+```shell
+zfb@localhost:~$ script -t 2>time.file -a -f command.log
+Script started, file is command.log
+zfb@localhost:~$ echo "hello, world"
+hello, world
+zfb@localhost:~$ echo $(date "+%Y-%m-%d %H:%M:%S")

+-rw-r--r--  1 zfb zfb  790 Dec 23 20:49 time.file
+zfb@localhost:~$ exit
+
+zfb@localhost:~$
+```
+
+其中，只有命令`scriptreplay -d 1 -m 2 -t time.file -s command.log`是用户输入，其他均为自动呈现（且视觉效果与真实用户的操作一致）。通过查看上面输出的时间`2020-12-23 20:48:46`，可以证明，这是重新播放当时的记录，而非重新执行一遍命令。也就是说，可以把`time.file`和`command.log`文件移动到任意一台支持`scriptreplay`命令的机器上，都可以动态重现命令输入与终端回显。

+**将源目录同步到目标目录**
+
+```shell
+$ rsync -r source destination
+```
+
+上面命令中，`-r` 表示递归，即包含子目录。注意，`-r`是必须的，否则 `rsync` 运行不会成功。`source` 目录表示源目录，`destination` 表示目标目录。
+
+**多个文件或目录同步**
+
+```shell
+$ rsync -r source1 source2 destination
+```
+
+上面命令中，`source1`、`source2` 都会被同步到 `destination` 目录。
+
+**同步元信息**
+
+`-a` 参数可以替代 `-r`，除了可以递归同步以外，还可以同步元信息（比如修改时间、权限等）。由于 `rsync` 默认使用文件大小和修改时间决定文件是否需要更新，所以 `-a` 比 `-r` 更有用。下面的用法才是常见的写法。
+
+```shell
+$ rsync -a source destination
+```
+
+目标目录 `destination` 如果不存在，`rsync` 会自动创建。执行上面的命令后，源目录 `source` 被完整地复制到了目标目录 `destination` 下面，即形成了 `destination/source` 的目录结构。
+
+如果只想同步源目录 `source` 里面的内容到目标目录 `destination` ，则需要在源目录后面加上斜杠。
+
+```shell
+$ rsync -a source/ destination
+```
+
+上面命令执行后，`source` 目录里面的内容，就都被复制到了 `destination` 目录里面，并不会在 `destination` 下面创建一个 `source` 子目录。
+
+
+**模拟执行的结果**
+
+如果不确定 `rsync` 执行后会产生什么结果，可以先用 `-n` 或 `--dry-run` 参数模拟执行的结果。
+
+```shell
+$ rsync -anv source/ destination
+```
+
+上面命令中，`-n` 参数模拟命令执行的结果，并不真的执行命令。`-v` 参数则是将结果输出到终端，这样就可以看到哪些内容会被同步。
+
+**目标目录成为源目录的镜像副本**
+
+默认情况下，`rsync` 只确保源目录的所有内容（明确排除的文件除外）都复制到目标目录。它不会使两个目录保持相同，并且不会删除文件。如果要使得目标目录成为源目录的镜像副本，则必须使用 `--delete` 参数，这将删除只存在于目标目录、不存在于源目录的文件。
+
+```shell
+$ rsync -av --delete source/ destination
+```
+
+上面命令中，`--delete` 参数会使得 `destination` 成为 `source` 的一个镜像。
+
+
+**排除文件**
+
+有时，我们希望同步时排除某些文件或目录，这时可以用--exclude参数指定排除模式。
+
+```shell
+$ rsync -av --exclude='*.txt' source/ destination
+# 或者
+$ rsync -av --exclude '*.txt' source/ destination
+```
+
+上面命令排除了所有 `TXT` 文件。
+
+注意，`rsync` 会同步以"点"开头的隐藏文件，如果要排除隐藏文件，可以这样写 `--exclude=".*"`。
+
+如果要排除某个目录里面的所有文件，但不希望排除目录本身，可以写成下面这样。
+
+```shell
+$ rsync -av --exclude 'dir1/*' source/ destination
+```
+
+多个排除模式，可以用多个 `--exclude` 参数。
+
+```shell
+$ rsync -av --exclude 'file1.txt' --exclude 'dir1/*' source/ destination
+```
+
+多个排除模式也可以利用 Bash 的大扩号的扩展功能，只用一个 `--exclude` 参数。
+
+```shell
+$ rsync -av --exclude={'file1.txt','dir1/*'} source/ destination
+```
+
+如果排除模式很多，可以将它们写入一个文件，每个模式一行，然后用 `--exclude-from` 参数指定这个文件。
+
+```shell
+$ rsync -av --exclude-from='exclude-file.txt' source/ destination
+```
+
+**指定必须同步的文件模式**
+
+`--include` 参数用来指定必须同步的文件模式，往往与 `--exclude` 结合使用。
+
+```shell
+$ rsync -av --include="*.txt" --exclude='*' source/ destination
+```
+
+上面命令指定同步时，排除所有文件，但是会包括 `TXT` 文件。

+正常情况下，当你退出一个窗口中最后一个程序（通常是bash）后，这个窗口就关闭了。另一个关闭窗口的方法是使用`ctrl`+`a` 键，然后按下`k`键，最后当提示你是否要杀死这个会话时按下`y`键，这个快捷键会杀死当前的窗口，同时也将杀死这个窗口中正在运行的进程。
 
 如果一个Screen会话中最后一个窗口被关闭了，那么整个Screen会话也就退出了，screen进程会被终止。
 
 除了依次退出/杀死当前Screen会话中所有窗口这种方法之外，还可以使用快捷键C-a :，然后输入quit命令退出Screen会话。需要注意的是，这样退出会杀死所有窗口并退出其中运行的所有程序。其实C-a :这个快捷键允许用户直接输入的命令有很多，包括分屏可以输入split等，这也是实现Screen功能的一个途径，不过个人认为还是快捷键比较方便些。
 
+此外，这里再介绍另外一种快速杀死一个Screen会话的命令：
+
+```
+[root@TS-DEV ~]# screen -ls   #列出存在的会话
+[root@TS-DEV ~]# screen -XS "会话id或者名称" quit
+```
+
+**示例：**

+```

+### 网络连接状态详解
+
+**共有12中可能的状态**，前面11种是按照TCP连接建立的三次握手和TCP连接断开的四次挥手过程来描述的：
+
+1. LISTEN：首先服务端需要打开一个socket进行监听，状态为 LISTEN，侦听来自远方TCP端口的连接请求 ；
+
+2. SYN_SENT：客户端通过应用程序调用connect进行active open，于是客户端tcp发送一个SYN以请求建立一个连接，之后状态置为 SYN_SENT，在发送连接请求后等待匹配的连接请求；
+
+3. SYN_RECV：服务端应发出ACK确认客户端的 SYN，同时自己向客户端发送一个SYN，之后状态置为，在收到和发送一个连接请求后等待对连接请求的确认；
+
+4. ESTABLISHED：代表一个打开的连接，双方可以进行或已经在数据交互了， 代表一个打开的连接，数据可以传送给用户；
+
+5. FIN_WAIT1：主动关闭(active close)端应用程序调用close，于是其TCP发出FIN请求主动关闭连接，之后进入FIN_WAIT1状态， 等待远程TCP的连接中断请求，或先前的连接中断请求的确认；
+
+6. CLOSE_WAIT：被动关闭(passive close)端TCP接到FIN后，就发出ACK以回应FIN请求(它的接收也作为文件结束符传递给上层应用程序)，并进入CLOSE_WAIT， 等待从本地用户发来的连接中断请求；
+
+7. FIN_WAIT2：主动关闭端接到ACK后，就进入了 FIN-WAIT-2，从远程TCP等待连接中断请求；
+
+8. LAST_ACK：被动关闭端一段时间后，接收到文件结束符的应用程 序将调用CLOSE关闭连接，这导致它的TCP也发送一个 FIN,等待对方的ACK.就进入了LAST-ACK，等待原来发向远程TCP的连接中断请求的确认；
+
+9. TIME_WAIT:在主动关闭端接收到FIN后，TCP 就发送ACK包，并进入TIME-WAIT状态，等待足够的时间以确保远程TCP接收到连接中断请求的确认；
+
+10. CLOSING: 比较少见，等待远程TCP对连接中断的确认；
+
+11. CLOSED: 被动关闭端在接受到ACK包后，就进入了closed的状态，连接结束，没有任何连接状态；
+
+12. UNKNOWN：未知的Socket状态；
+
+**常见标志位**
+
+* SYN: (同步序列编号,Synchronize Sequence Numbers)该标志仅在三次握手建立TCP连接时有效。表示一个新的TCP连接请求。
+
+* ACK: (确认编号,Acknowledgement Number)是对TCP请求的确认标志,同时提示对端系统已经成功接收所有数据。
+
+* FIN: (结束标志,FINish)用来结束一个TCP回话.但对应端口仍处于开放状态,准备接收后续数据。

 符号链接也称为软链接，是将一个路径名链接到一个文件。这些文件是一种特别类型的文件。事实上，它只是一个文本文件（如下所示的abc文件），其中包含它提供链接的另一个文件的路径名，如虚线箭头所示。另一个文件是实际包含所有数据的文件。所有读、写文件内容的命令被用于符号链接时，将沿着链接方向前进来访问实际的文件。

 #### 注意
 
 1. 该命令是`GNU coreutils`包中的命令，相关的帮助信息请查看`man pwd`或`info coreutils 'pwd invocation'`。

 2. 启动或关闭内建命令请查看`enable`命令，关于同名优先级的问题请查看`builtin`命令的例子部分的相关讨论。

 3. 在不禁用内建且当前环境没有定义`pwd`函数的情况下，使用`/usr/bin/pwd`指向`coreutils`的`pwd`，使用`pwd`指向bash内建的`pwd`。

##### 修改的错误

1. 去掉 `21` 行了 `-c` 选项的错误的长选项 `--chars` ，并将其追加到了23行后面
2. 去掉了 `23` 行的 *不可和-c选项一起使用*，因为两者可以一起使用

##### 调整的格式

1. 将 `21-24` 行一些行末的 `；。` 改为了 `。`
2. 将 `21-24` 行一些长选项的 `——` 改为了 `--`
3. `26-27` 行追加了句号

##### 谈不上错误但我感觉可能会给读者造成误解

1. 去掉了 `21-24` 行 `只显示` 的 `只` 字，因为这些参数可以一起出现并按 `行数 字数 字符数 字节数 最长行长度` 的顺序打印，而 `只` 字可能会让看的人产生误解，感觉这些参数只能单独互斥地使用

 ## 扩展知识
 
 Linux具有为一个文件起多个名字的功能，称为链接。被链接的文件可以存放在相同的目录下，但是必须有不同的文件名，而不用在硬盘上为同样的数据重复备份。另外，被链接的文件也可以有相同的文件名，但是存放在不同的目录下，这样只要对一个目录下的该文件进行修改，就可以完成对所有目录下同名链接文件的修改。对于某个文件的各链接文件，我们可以给它们指定不同的存取权限，以控制对信息的共享和增强安全性。

 符号链接也称为软链接，是将一个路径名链接到一个文件。这些文件是一种特别类型的文件。事实上，它只是一个文本文件（如下所示的abc文件），其中包含它提供链接的另一个文件的路径名，如虚线箭头所示。另一个文件是实际包含所有数据的文件。所有读、写文件内容的命令被用于符号链接时，将沿着链接方向前进来访问实际的文件。

+telinit
+===
+
+切换当前正在运行系统的运行等级
+
+## 补充说明
+
+**telinit命令** 用于切换当前正在运行的Linux系统的运行等级。
+
+_RUNLEVEL_ 参数应该是多用户运行级别 `2-5` 之一，`0` 用于停止系统，`6` 用于重新启动系统，或 `1` 用于使系统进入单用户模式。
+
+通常您会使用 `shutdown(8)` 工具来停止或重新启动系统，或者将其降低到单用户模式。
+
+_RUNLEVEL_ 也可能是 S 或 s ，这会将系统直接置于单用户模式，而无需先实际停止进程，您可能不希望这样。
+
+通过发出 `runlevel(7)` 事件来更改运行级别，该事件包括 _RUNLEVEL_ 环境变量中的新运行级别以及 PREVLEVEL 变量中的先前运行级别（从环境或 `/var/run/utmp` 获得）。
+
+**telinit** 会将新的运行级别写入 `/var/run/utmp` 并将新条目附加到 `/var/log/wtmp`。
+
+###  语法
+
+```shell
+telint(选项)(参数)
+telinit [OPTION]... RUNLEVEL
+```
+
+###  选项
+
+```shell
+-t：指定等待的秒数。
+-e 键=值
+```
+
+这指定了与 _RUNLEVEL_ 和 _PREVLEVEL_ 一起包含在事件中的附加环境变量。
+
+###  参数
+
+运行等级：指定要切换的运行等级。
+
+### Environment
+
+RUNLEVEL
+
+如果设置优先于从 `/var/run/utmp` 读取，`telinit` 将从该环境变量读取当前运行级别
+
+### Files
+
+- `/var/run/utmp` 将从哪里读取当前运行级别； 此文件也将使用新的运行级别进行更新。
+- `/var/log/wtmp` 新的运行级别记录将附加到此文件中以获取新的运行级别。

+```
+
+### 实例
+
+**过滤输出**
+
+`journalctl` 可以根据特定字段过滤输出。如果过滤的字段比较多，需要较长时间才能显示出来。
+
+示例：
+
+显示本次启动后的所有日志：
+
+```shell
+journalctl -b
+```
+
+不过，一般大家更关心的不是本次启动后的日志，而是上次启动时的（例如，刚刚系统崩溃了）。可以使用 -b 参数：
+
+- `journalctl -b -0` 显示本次启动的信息
+- `journalctl -b -1` 显示上次启动的信息
+- `journalctl -b -2` 显示上上次启动的信息 `journalctl -b -2`
+
+只显示错误、冲突和重要告警信息
+
+```shell
+journalctl -p err..alert
+```
+
+也可以使用数字， `journalctl -p 3..1`。如果使用单个 number/keyword，则 `journalctl -p 3` - 还包括所有更高的优先级。
+
+显示从某个日期 ( 或时间 ) 开始的消息:
+
+```shell
+journalctl --since="2012-10-30 18:17:16"
+```
+
+显示从某个时间 ( 例如 20分钟前 ) 的消息:
+
+```shell
+journalctl --since "20 min ago"
+```
+
+显示最新信息
+
+```shell
+journalctl -f
+```
+
+显示特定程序的所有消息:
+
+```shell
+journalctl /usr/lib/systemd/systemd
+```
+
+显示特定进程的所有消息:
+
+```shell
+journalctl _PID=1
+```
+
+显示指定单元的所有消息：
+
+```shell
+journalctl -u man-db.service
+```
+
+显示内核环缓存消息r:
+
+```shell
+journalctl -k
+```
+
+**手动清理日志**
+
+`/var/log/journal` 存放着日志, `rm` 应该能工作. 或者使用 `journalctl`,
+
+例如:
+
+清理日志使总大小小于 100M:
+
+```shell
+journalctl --vacuum-size=100M
+```
+
+清理最早两周前的日志.
+
+```shell
+journalctl --vacuum-time=2weeks
+```

+     --adjust-system-clock 更改本地 RTC 模式时调整系统时钟。
+
+Commands:
+  status                   显示当前的时间设置。
+  set-time TIME            设置系统时间。
+  set-timezone ZONE        设置系统时区。
+  list-timezones           显示已知时区。
+  set-local-rtc BOOL       控制 RTC 是否在当地时间。（BOOL 的值可以是 1 / true 或 0 / false）
+  set-ntp BOOL             启用或禁用网络时间同步。（BOOL 的值可以是 1 / true 或 0 / false）
+  timesync-status          显示 systemd-timesyncd 的状态。

+        RTC time: 五 2022-04-08 17:04:02
+       Time zone: Asia/Shanghai (CST, +0800)
+     NTP enabled: n/a
+NTP synchronized: no
+ RTC in local TZ: yes
+      DST active: n/a
+```
+
+显示系统所有可用的时区
+
+```shell
+$ timedatectl show
+Unknown operation show
+$ timedatectl list-timezones
+Africa/Abidjan
+Africa/Accra
+Africa/Addis_Ababa
+```
+
+将本地时区从上海（Asia/Shanghai）设置为阿姆斯特丹（Europe/Amsterdam）
+
+```shell
+$ timedatectl set-timezone "Europe/Amsterdam"
+```
+
+将本地时区设置为协调世界时（UTC）
+
+```shell
+$ timedatectl set-timezone UTC
+```
+
+设置系统时间（格式：HH:MM:SS）
+
+```shell
+$ timedatectl set-time "07:25:46"
+```
+
+设置系统日期（格式：YYYY-MM-DD）
+
+```shell
+$ timedatectl set-time "2021-12-12"
+```
+
+如果只设置日期，那么时间将默认设置为 “00:00:00″（建议同时设置日期和时间）
+
+```shell
+$ timedatectl set-time "2021-12-12 07:25:46"
+```
+
+将硬件时钟（RTC）设置为本地时区（不建议，RTC 时钟统一使用 UTC 更恰当，避免在时区更改和夏令时调整方面产生各种问题）
+
+```shell
+$ timedatectl set-local-rtc 1
+```
+
+将硬件时钟（RTC）设置为协调世界时间（UTC）
+
+```shell
+$ timedatectl set-local-rtc 0
+```
+
+启用 NTP 自动时间同步
+
+```shell
+$ timedatectl set-ntp true
+```
+
+禁用 NTP 自动时间同步
+
+```shell
+$ timedatectl set-ntp false
+```
+
+查看 systemd-timesyncd 服务的状态
+
+```shell
+$ timedatectl timesync-status

+Poll interval: 17min 4s (min: 32s; max 34min 8s)
+         Leap: normal
+      Version: 4
+      Stratum: 2
+    Reference: 91EECB0E
+    Precision: 1us (-23)
+Root distance: 29.922ms (max: 5s)
+       Offset: +2.497ms
+        Delay: 199.540ms
+       Jitter: 5.834ms
+ Packet count: 6
+    Frequency: +13.039ppm
+```
+
+`systemd-timedated` 可能默认配置了谷歌的 NTP 服务器（如 time1.google.com），为了顺利完成网络时间同步，您可以编辑 `/etc/systemd/timesyncd.conf` 文件添加自己的 NTP 服务器地址。

+pidstat
+===
+监控进程的系统资源占用情况
+
+## 说明
+**pidstat**是sysstat工具的一个命令，用于监控全部或指定进程的cpu、内存、线程、设备IO等系统资源的占用情况。
+pidstat首次运行时显示自系统启动开始的各项统计信息，之后运行pidstat将显示自上次运行该命令以后的统计信息。用户可以通过指定统计的次数和时间来获得所需的统计信息。
+
+### 语法
+```shell
+pidstat [ 选项 ] [ <时间间隔> ] [ <次数> ]
+```
+#### 选项
+- u：默认的参数，显示各个进程的cpu使用统计
+- r：显示各个进程的内存使用统计
+- d：显示各个进程的IO使用情况
+- w：显示每个进程的上下文切换情况
+- t：显示到线程的统计信息
+- p：指定进程号
+- T { TASK | CHILD | ALL }
+ 这个选项指定了pidstat监控的。TASK表示报告独立的task，CHILD关键字表示报告进程下所有线程统计信息。ALL表示报告独立的task和task下面的所有线程。
+ 注意：task和子线程的全局的统计信息和pidstat选项无关。这些统计信息不会对应到当前的统计间隔，这些统计信息只有在子线程kill或者完成的时候才会被收集。
+- V：版本号
+- h：在一行上显示了所有活动，这样其他程序可以容易解析。
+- I：在SMP环境，表示任务的CPU使用率/内核数量
+- l：显示命令名和所有参数
+

+
+（序列 SdSn lnld/lnld% 也可以完成此功能，但错误检查略有不同。）
+
+
+^ 使用弹出的第一个值作为指数，第二个值作为基数，弹出两个值并进行幂运算。忽略指数的分数部分。
+
+
+| 弹出三个值并计算模幂。 弹出的第一个值用作约简模数； 这个值必须是一个非零数字，并且应该是一个整数。 弹出的第二个用作指数； 该值必须是非负数，并且该指数的任何小数部分都将被忽略。 弹出的第三个值是取幂的基数，它应该是一个整数。 对于小整数，这类似于序列 Sm^Lm%，但与 ^ 不同的是，此命令适用于任意大的指数。
+

+（序列 SdSn lnld/lnld% 也可以完成此功能，但错误检查略有不同。）
+
+
+`^` 使用弹出的第一个值作为指数，第二个值作为基数，弹出两个值并进行幂运算。忽略指数的分数部分。
+
+`|` 弹出三个值并计算模幂。 弹出的第一个值用作约简模数； 这个值必须是一个非零数字，并且应该是一个整数。 弹出的第二个用作指数； 该值必须是非负数，并且该指数的任何小数部分都将被忽略。 弹出的第三个值是取幂的基数，它应该是一个整数。 对于小整数，这类似于序列 Sm^Lm%，但与 ^ 不同的是，此命令适用于任意大的指数。
+
+`v` 弹出一个值，计算其平方根，然后压栈它。精度值的最大值和参数的精度用于确定结果中的小数位数。

+## 7z
+
+用于解压缩各种类型的压缩包，还拥有超高的压缩比。
+
+我用 7-Zip 解压过：zip、iso、7z压缩文件。
+
+## 安装
+在 Linux 中输入以下命令安装 7-Zip。
+
+```bash
+# Ubuntu 系统
+apt-get update
+apt-get install p7zip-full -y
+```
+
+## 实例
+
+介绍几个常用场景：解压、压缩、查看（压缩包内容）。
+
+1、将压缩文件 text.7z 在当前目录下解压缩。
+
+```bash
+7z x text.7z
+```
+
+2、将压缩文件 text.7z 在指定目录(/home/text)下解压缩。
+
+```bash
+# 注意 -o 用来指定解压缩文件存放目录，-o 后是没有空格的,直接接目录
+7z x text.7z -r -o/home/text
+```
+
+3、将文件 /home/text 压缩成 text.7z。
+
+```bash
+7z a text.7z -r /home/text
+```
+
+4、查看压缩包 text.7z 内容，但不解压。
+
+```bash
+7z l text.7z
+```

+groupmems
+===
+
+管理用户主要组的成员
+
+## 补充说明
+
+`groupmems` 命令允许用户管理他/她自己的组成员列表，而不需要超级用户权限。`groupmems` 实用程序适用于将其用户配置为以他们自己的名义主组（即来宾/来宾）的系统。
+
+只有作为管理员的超级用户可以使用 `groupmems` 来更改其他组的成员资格。
+
+###  语法
+
+```shell
+groupmems -a user_name | -d 用户名 | [-g 用户组名] | -l | -p
+```
+
+###  选项
+
+```bash
+-a, --add user_name # 将用户添加到组成员列表。如果 /etc/gshadow 文件存在，并且该组在 /etc/gshadow 文件中没有条目，则将创建一个新条目。
+
+-d, --delete user_name
+# 从组成员列表中删除用户。
+# 如果 /etc/gshadow 文件存在，用户将从组的成员和管理员列表中删除。
+# 如果 /etc/gshadow 文件存在，并且该组在 /etc/gshadow 文件中没有条目，则将创建一个新条目。
+
+-g, --group group_name # 超级用户可以指定要修改的组成员列表。
+-l, --list             # 列出组成员列表。
+-p, --purge            # 从组成员列表中清除所有用户。
+# 如果 /etc/gshadow 文件存在，并且该组在 /etc/gshadow 文件中没有条目，则将创建一个新条目。
+```
+
+## 配置
+
+`/etc/login.defs` 中的以下配置变量会更改此工具的行为：
+
+```shell
+MAX_MEMBERS_PER_GROUP (number)
+```
+
+每个组条目的最大成员数。 当达到最大值时，在 `/etc/group` 中启动一个新的组条目（行）（具有相同的名称、相同的密码和相同的 GID）。
+
+默认值为 0，表示组中的成员数量没有限制。
+
+此功能（拆分组）允许限制组文件中的行长度。 这有助于确保 NIS 组的行不超过 1024 个字符。
+
+如果你需要强制执行这样的限制，你可以使用 25。
+
+注意：并非所有工具都支持拆分组（即使在 Shadow 工具包中）。 除非你真的需要它，否则你不应该使用这个变量。
+
+## 例子
+
+groupmems 可执行文件应该在模式 2770 中作为用户 root 和组组。 系统管理员可以将用户添加到组中，以允许或禁止他们使用 groupmems 实用程序来管理他们自己的组成员列表。
+
+```shell
+$ groupadd -r groups
+$ chmod 2770 groupmems
+
+$ chown root.groups groupmems
+$ groupmems -g groups -a gk4
+```
+
+让我们创建一个新用户和一个新组并验证结果：
+
+```shell
+$ useradd student
+$ passwd student
+$ groupadd staff
+```
+
+使用户 student 成为组人员的成员：
+
+```shell
+$ groupmems -g staff -a student
+$ groupmems -g staff -l 
+```
+
+将用户添加到组：
+
+```shell
+$ groupmems -a mike -g SUPPORT
+$ groupmems --add mike -g SUPPORT 
+```
+
+从组中删除/移除用户：
+
+```shell
+$ groupmems -d mike SUPPORT -g SUPPORT
+$ groupmems --delete mike SUPPORT -g SUPPORT
+```
+
+更改组名称：
+
+```shell
+$ groupmems -g SUPPORT
+```
+
+从组中删除用户：
+
+```shell
+$ groupmems -p -g SUPPORT
+$ groupmems --purge -g SUPPORT
+```
+
+要列出组的成员：
+
+```shell
+$ groupmems -l -g SUPPORT
+$ groupmems --list -g SUPPORT
+```

+
+grub2-set-default后面的序号从0开始。所以，如果想设置第一个选项为默认启动内核，则可以使用下面的命令：
+
+```shell
+# grub2-set-default 0
+```
+如果想使用CentOS Linux (3.10.0-862.el7.x86_64) 7 (Core)内核版本,则可以将0改为2

+```
+
+`mkcert` 自动生成并安装一个本地 CA 到 root stores，并且生成 locally-trusted 证书。`mkcert` 不会自动使用证书来配置服务器，不过，这取决于你。
+
+## 安装
+
+> Warning: `mkcert` 自动生成的 `rootCA-key.pem` 文件提供了完整的能力来拦截你机器上的安全请求。请不要分享它。
+
+### macOS
+
+```zsh
+brew install mkcert
+brew install nss # 如果用 Firefox 的话
+```
+
+### Linux
+
+在 Linux 上，首先要安装 `certutil`
+
+```zsh
+sudo apt install libnss3-tools
+    -or-
+sudo yum install nss-tools
+    -or-
+sudo pacman -S nss
+    -or-
+sudo zypper install mozilla-nss-tools
+```
+
+然后可以使用 [Homebrew on Linux](https://docs.brew.sh/Homebrew-on-Linux) 来安装。
+
+```zsh
+brew install mkcert
+```
+
+或者从源码构建（要求 Go 1.13+）
+
+```zsh
+git clone https://github.com/FiloSottile/mkcert && cd mkcert
+go build -ldflags "-X main.Version=$(git describe --tags)"
+```
+
+又或者使用 [预构建的二进制文件](https://github.com/FiloSottile/mkcert/releases)。
+
+```zsh
+curl -JLO "https://dl.filippo.io/mkcert/latest?for=linux/amd64"
+chmod +x mkcert-v*-linux-amd64
+sudo cp mkcert-v*-linux-amd64 /usr/local/bin/mkcert
+```
+
+对于 Arch Linux 用户（比如我），[`mkcert`](https://www.archlinux.org/packages/community/x86_64/mkcert/) 在 Arch Linux 官方仓库中可用。
+
+```zsh
+sudo pacman -S mkcert
+```
+
+### Windows
+
+使用 [Chocolatey](https://chocolatey.org/)
+
+```zsh
+choco install mkcert
+```
+
+或者使用 Scoop
+
+```zsh
+scoop bucket add extras
+scoop install mkcert
+```
+
+或者从源码构建（要求 Go 1.10+） ，或者使用 [预构建的二进制文件](https://github.com/FiloSottile/mkcert/releases)。
+
+如果遇到权限问题，请使用管理员运行 `mkcert`
+
+## 支持的 root stores
+
+`mkcert` 支持以下 root stores：
+
+- macOS system store
+
+- Windows system store
+
+- Linux 发行版提供
+  
+  - `update-ca-trust` （Fedora，RHEL，CentOS）或者
+  
+  - `update-ca-certificates` （Ubuntu，Debian，OpenSUSE，SLES）或者
+  
+  - `trust` （Arch）
+
+- Firefox （仅 macOS 和 Linux）
+
+- Chrome 和 Chromium
+
+- Java（当 `JAVA_HOME` 被设置时）
+
+为了把 local root CA 装到这些 root stores 中，你可以设置 `TRUST_STORES` 环境变量到一个逗号分隔的 list。有这些选项："system","java" 和 "nss"（包括了 Firefox）。
+
+## 高级 topics
+
+---
+
+### 高级选项
+
+```zsh
+    -cert-file FILE, -key-file FILE, -p12-file FILE
+        自定义输出路径.
+
+    -client
+        生成供客户端认证使用的证书.
+
+    -ecdsa
+        生成使用一个 ECDSA （一种椭圆曲线签名算法）key 来生成证书.
+
+    -pkcs12
+        生成一个 ".p12" PKCS #12 文件，也可以被识别为 ".pfx" 文件,
+        包含 cert 和 key for legacy applications.
+
+    -csr CSR
+        生成一个给予 CSR（证书签名申请） 的证书。
+    与除了 -install 和 -cert-file 以外的其它所以 flag 和参数冲突！
+```
+
+[SSL 证书 什么是CSR？-常见问题-文档中心-腾讯云](https://cloud.tencent.com/document/product/400/5367)
+
+> **请注意！** 你必须把这些选项放在域名列表之前。
+
+### 例如
+
+```zsh
+mkcert -key-file key.pem -cert-file cert.pem example.com *.example.com
+```
+
+### S/MIME （邮件安全证书）
+
+用下面这种方式 `mkcert` 会生成一个 S/MIME 证书：
+
+```zsh
+mkcert filippo@example.com
+```
+
+### 移动设备
+
+对于要让移动设备信任证书的情况，你得安装 root CA。就是 `rootCA.pem` 这个文件，可以通过 `mkcert -CAROOT` 打印出这个文件所在的目录。
+
+在 iOS 上，你也可以使用 AirDrop，把 CA 邮件发给你自己，或者通过一个 HTTP server 提供它。在打开它之后，你需要  [install the profile in Settings > Profile Downloaded](https://github.com/FiloSottile/mkcert/issues/233#issuecomment-690110809) and then [enable full trust in it](https://support.apple.com/en-nz/HT204477) 。
+
+对于 Android ，你得安装这个 CA 然后在应用程序的开发版本中启用 user roots。可以看一看这个 [StackOverflow 回答](https://stackoverflow.com/a/22040887/749014) 。
+
+### 用 Node.js 来使用这个 root
+
+Node 不使用 system root store，所以它不会自动接受 `mkcert` 证书。相反，你得设置 [`NODE_EXTRA_CA_CERTS`](https://nodejs.org/api/cli.html#cli_node_extra_ca_certs_file) 环境变量。
+
+```zsh
+export NODE_EXTRA_CA_CERTS="$(mkcert -CAROOT)/rootCA.pem"
+```
+
+### 改变 CA 文件的位置
+
+CA 证书和它的 key 被存储在用户家目录的一个文件夹中。一般来说你不会想去关注它的位置，因为它会被自动装载。但是你可以通过 `mkcert -CAROOT` 来打印这个目录位置。
+
+如果你想要管理单独的 CA 们，你可以使用 `\$CAROOT` 环境变量来设置 mkcert 放置和寻找 CA files 的路径。
+
+### 在其它系统上安装 CA
+
+安装 trust store 不需要 CA key（只要 CA），所以你可以导出 CA，并且使用 `mkcert` 来安装到其它机器上。
+
+- 找到 `rootCA.pem` 文件，可以用 `mkcert -CAROOT` 找到对应目录。
+
+- 把它 copy 到别的机器上。
+
+- 设置 `\$CAROOT` 为 `rootCA.pem` 所在目录。
+
+- 运行 `mkcert -install`(arch linux 可以 `sudo trust anchor --store rootCA.pem`，其它发行版可以用自带的命令手动添加来信任 CA)
+
+请千万记住 `mkcert` 是用于开发目的的，不建议用于生产，所以它不应该被用到用户终端上，并且你不应该导出或者共享 `rootCA-key.pem` 。

-brew install mkcert
-brew install nss # 如果用 Firefox 的话
+```bash
+$ brew install mkcert
+$ brew install nss # 如果用 Firefox 的话

 ### Linux
 
 在 Linux 上，首先要安装 `certutil`
 
-```zsh
-sudo apt install libnss3-tools
-    -or-
-sudo yum install nss-tools
-    -or-
-sudo pacman -S nss
-    -or-

 ```
 
 然后可以使用 [Homebrew on Linux](https://docs.brew.sh/Homebrew-on-Linux) 来安装。
 
-```zsh
-brew install mkcert
+```bash
+$ brew install mkcert
 ```
 
 或者从源码构建（要求 Go 1.13+）
 
-```zsh
+```bash
 git clone https://github.com/FiloSottile/mkcert && cd mkcert
 go build -ldflags "-X main.Version=$(git describe --tags)"
 ```
 
 又或者使用 [预构建的二进制文件](https://github.com/FiloSottile/mkcert/releases)。
 
-```zsh
-curl -JLO "https://dl.filippo.io/mkcert/latest?for=linux/amd64"
-chmod +x mkcert-v*-linux-amd64
-sudo cp mkcert-v*-linux-amd64 /usr/local/bin/mkcert

 安装 trust store 不需要 CA key（只要 CA），所以你可以导出 CA，并且使用 `mkcert` 来安装到其它机器上。
 
 - 找到 `rootCA.pem` 文件，可以用 `mkcert -CAROOT` 找到对应目录。
-
 - 把它 copy 到别的机器上。
-
 - 设置 `\$CAROOT` 为 `rootCA.pem` 所在目录。
-
 - 运行 `mkcert -install`(arch linux 可以 `sudo trust anchor --store rootCA.pem`，其它发行版可以用自带的命令手动添加来信任 CA)
 
 请千万记住 `mkcert` 是用于开发目的的，不建议用于生产，所以它不应该被用到用户终端上，并且你不应该导出或者共享 `rootCA-key.pem` 。

+在“非交互模式”下，用户可以针对一个主机或域名仅仅获取特定的名称或所需信息，此时也可以指定查询的DNS服务器。
 
 进入交互模式，直接输入nslookup命令，不加任何参数，则直接进入交互模式，此时nslookup会连接到默认的域名服务器（即`/etc/resolv.conf`的第一个dns地址）。或者输入`nslookup -nameserver/ip`。进入非交互模式，就直接输入`nslookup 域名`就可以了。

+#### 以指定的间隔运行，同时又能通知硬盘的测试结果
+首先，编辑smartctl的配置文件(/etc/default/smartmontools)以便在系统启动时启动smartd，并以秒为单位指定间隔时间（如7200 = 2小时）
+
+```shell
+start_smartd=yes
+smartd_opts="--interval=7200"
+```
+
+下一步，编辑smartd的配置文件（/etc/smartd.conf），添加以下行内容。
+```shell
+/dev/sda -m myemail@mydomain.com -M test
+```
+
+选项说明 \
+-m ：指定发送测试报告到某个电子邮件地址。这里可以是系统用户比如root，或者如果服务器已经配置成发送电子邮件到系统外部，则是类似于myemail@mydomain.com的邮件地址。\
+-M ：指定发送邮件报告的期望类型。\
+once：为检测到的每种磁盘问题只发送一封警告邮件。\
+daily：为检测到的每种磁盘问题每隔一天发送一封额外的警告提醒邮件。\
+diminishing：为检测到的每种问题发送一封额外的警告提醒邮件，开始是每隔一天，然后每隔两天，每隔四天，以此类推。每个间隔是前一次间隔的2倍。\
+test：只要smartd一启动，立即发送一封测试邮件。\
+exec PATH：取代默认的邮件命令，运行PATH路径下的可执行文件。PATH必须指向一个可执行的二进制文件或脚本。当检测到一个问题时，可以指定执行一个期望的动作（闪烁控制台、关闭系统等等）。
+
+保存改动并重启smartd。

 ## 补充说明
 
-**curl命令** 是一个利用URL规则在命令行下工作的文件传输工具。它支持文件的上传和下载，所以是综合传输工具，但按传统，习惯称curl为下载工具。作为一款强力工具，curl支持包括HTTP、HTTPS、ftp等众多协议，还支持POST、cookies、认证、从指定偏移处下载部分文件、用户代理字符串、限速、文件大小、进度条等特征。做网页处理流程和数据检索自动化，curl可以祝一臂之力。

 ###  选项
 
-```shell
-ar 允许你 在第一个 命令行 参数中 以任意 顺序 混合 指定 操作码p 和修饰符mod .
-
-只要你 愿意, 也可以 用破折号 作为 命令行 第一个 参数的 开始.
-
-p 关键字 指明 要执行的 操作, 只能 指明为 如下 之一:
-
-d      从档案中删除 模块. 通过files 指明 要删除的 模块的 名称; 如果 没有 指出 要删除的  文件  名称,  档案不会  改变  任何
-      内容.
-
-      如果 给出了'v' 修饰符,ar 会例出 它删除的 每一个 模块.
-
-m      用此 操作 在档案中移动 成员.
-      如果 某个 符号名 在档案的 多个 成员中 有定义, 那么 程序 怎样 连接 档案 文件 得到的 结果 可能是 不同的.
-      如果  没有为m 指定 修饰符, 由files 指出的 成员 将移动到 档案的末尾 ; 可以 通过 `a', `b' 或 `i' 等修饰符, 指定 成员
-      移动的 具体 位置.
-
-p      在标准 输出上 打印 档案中 指定的 成员.  如果 给出了`v' 修饰符, 在 打印 成员 内容 之前, 先打印 成员的 名字.
-      如果没有 指明files 参数, 档案中 所有的 成员 都会被 打印 出来.
-
-q      快速 追加; 增加 files 到 archive 的末尾, 不进行 替换 检查.
-      修饰符 `a' `b' 和 `i'不 影响此 操作, 新成员 始终 追加到 档案的 末尾处.
-      修饰符 `v' 可以使 ar 列出 它追加的 所有文件.
-      由于 本功能 是用于 快速操作, 即使 档案中 有 符号表 索引 也不 进行 更新; 可以 使用 `ar s' 或 ranlib 明确 要求  更新
-      这些索引.
-
-      在为快速 追加 重建 索引时,由于 有 太多 不同的 系统, 所以 GNU ar 采用 `q' 作为 `r'的一个 同义字.
-
-r      把文件  files  插入 archive ( 替换 ). 本操作与 `q' 是不同的, 如果 档案中 已有的 某个 成员与 插入 文件的 名称 相同,
-      此成员 将被删除.
-      如果 不存在 名称为 files 的文件, ar 显示 一个 错误 消息, 并且 保留 档案中 已有的 同名 成员.
-      缺省情况下, 新成员 增加到 挡案的 末尾; 可以 通过 使用 `a' `b' 或 `i' 等修饰符 指定 相对于 已有 成员的 位置.
-      通过 使用 `v' 修饰符 会为每个 插入的 文件 产生 一行 输出, 根据 输出中的 字符 `a' 或 `r' 可以 表明 该文件  是追加的
-      (没有 删除 以前的成员) 还是 替换的.
-
-t      显示  一个 archive 档案 所包含 内容的 列表 , 或 档案中的 由 files 指出的 文件 列表.  通常 只显示 成员的 名称, 如果
-      使用 `v' 修饰符, 可以 得到 成员的 权限, 时间属性, 属主, 组和 大小.
-
-      如果 没有 指出 files, 档案中的 所有 文件 都会 列出.
-
-      如果 档案中 (称为 `b.a') 有多个 同名 成员 (称为 `fie'), `ar t b.a fie' 仅仅 列出 第一个; 要看到 它们的 全部,  必须
-      要求 完整的 列表 —在本例中是 `ar t b.a'.
-
-x      从档案中 抽取  成员 (名称为 files) .  如果 使用 `v' 修饰符, ar 会列出 它抽取的 每一个 文件的 名字.
-      如果没有给出 files, 抽取 档案中 所有的 文件.
-
-可以在 操作符 p 后紧随 一定数量的 修饰符 mod 以指明 操作的 各种 行为.
-
-a      增加 文件到 档案中 已有 成员 之后  , 如果 使用了 修饰符 a, 必须在 档案 名称 archive 之前 以 membername 参数的 形式
-      给出 档案中 已有 成员的 名字.
-
-b      增加 文件到 档案中 已有 成员 之前  , 如果 使用了 修饰符 b, 必须在 档案 名称 archive 之前 以 membername 参数的 形式
-      给出 档案中 已有 成员的 名字.  (和修饰符 `i' 相同).
-
-c      建立    档案.  指定的 档案 archive 始终 会被建立, 如果 你要求 执行的是 更新, 通过 此修饰符 建立 档案时 会给出 一个
-      警告.
-      
-f      截短 档案成员的 名字.  ar 通常 允许 任意 长度的 文件名, 但这会 导致 与某些 系统上的 ar 出现 兼容性  问题,  使用  f
-      修饰符 可以 在往档案中 追加 文件时 把名字 截短.
-
-i      插入 文件到 档案中 已有 成员 之前  , 如果 使用了 修饰符 i, 必须在 档案 名称 archive 之前 以 membername 参数的 形式
-      给出 档案中 已有 成员的 名字.  (与修饰符 `b' 相同).
-
-l      接受此修饰符, 但不起作用.
-
-N      使用 count 参数. 本修饰符 用于 在档案中 有多个 同名 成员的 情况.  删除 或抽取 档案中 给定 名字的第 count 个实例.
-
-o      抽取 成员时 保留 他们 原始的  时间属性. 如果 没有 此修饰符, 文件以抽取 的时间 作为 它的时间 属性.
-
-P      匹配 档案中的 名字时 使用 完整的 路径名.  ar 不能 建立 使用 完整 路径名的 档案  (这不符合  POSIX  标准),  但其它的
-      档案  工具  能够建立, 本选项 会使 ar 在抽取 由其它 工具 建立的 档案 文件时, 使用完整的 路径名 去匹配 档案中 成员的
-      名字.
-
-s      即使 没有对 档案 进行 改变, 用本 修饰符 也可以 往档案中 写一个 目标 文件的 索引 或更新 已经 存在的  索引.   可以与
-      其它 操作 一起 使用 本修饰符, 也可以 单独使用.  对一个 档案 执行 `ar s' 与执行 `ranlib' 等价.
-
-S      不生成  档案的 符号表. 这可以 加速 建立 大的档案 文件的 过程,但这样 建立的 档案 不能被 连接器 使用, 为建立 符号表,
-      在最后 执行 `ar' 时应该 不用 `S' 修饰符, 或者 对档案 执行 一次 `ranlib' .
-
-u      通常ar r... 把所有 列出的 文件 插入到 档案中, 如果 希望 仅仅 插入比 档案中 已有 成员 更新的  文件时,  就应该  使用
-      此修饰符.   `u'  修饰符  仅允许  与 `r' (替换) 操作 一起 使用.  某些 情况下, 由于 用 `q' 操作 比较 文件的 时间属性
-      会失去 速度上的 优势, 所以 不允许 执行 `qu' 组合操作.
-
-v      使用本修饰符可以进行 冗余的 操作。附加了此修饰符时，很多操作会显示 更多的消息，如处理的文件名等。
-V      显示 ar 的版本号。

 fgrep 命令于 grep 和 egrep 命令不同，因为它搜索字符串而不是搜索匹配表达式的模式。fgrep 命令使用快速的压缩算法。`$, *, &#91;, |, (, )`和`\`等字符串被 fgrep 命令按字面意思解释。这些字符并不解释为正则表达式，但它们在 grep 和 egrep 命令中解释为正则表达式。因为这些字符对于 shell 有特定的含义，完整的字符串应该加上单引号`‘ ... ’`。. 如果没有指定文件， fgrep 命令假定标准输入。一般，找到的每行都复制到标准输出中去。如果不止一个输入文件，则在找到的每行前打印文件名。

 ## 补充说明
 
-**time命令** 用于统计给定命令所花费的总时间。
+`time` 命令是用来确定一个给定的命令需要运行多长时间。它对于测试你的脚本和命令的性能很有用。
 
-###  语法
+例如，如果你有两个不同的脚本在做同样的工作，你想知道哪一个表现得更好，你可以用 Linux 的时间命令来确定每个脚本的执行时间。
+
+该指令是 shell 内指令，也是一个软件包，**对于软件包的说明在这篇文档靠下的部分**
+
+## 语法

 当测试一个程序或比较不同算法时，执行时间是非常重要的，一个好的算法应该是用时最短的。所有类UNIX系统都包含time命令，使用这个命令可以统计时间消耗。例如：
 
 ```shell
-[root@localhost ~]# time ls
+$ time ls
 anaconda-ks.cfg  install.log  install.log.syslog  satools  text
 
 real    0m0.009s

 sys     0m0.007s
 ```
 
-输出的信息分别显示了该命令所花费的real时间、user时间和sys时间。
+这里的输出会因为使用的发行版本不同而导致展示的结果不同，比如：
+
+```shell
+# Bash
+real 0m33.961s
+user 0m0.340s
+sys 0m0.940s
+
+# Zsh

+```
+
+`real` 或者 `total` 或者 `elapsed`（挂钟时间）是指从调用开始到结束的时间。它是指从你按下回车键的那一刻开始，到命令完成的那一刻为止的时间。
+user - 在用户模式下花费的CPU时间。
+system 或 sys - 在内核模式下花费的CPU时间。
+
+## 软件包
+
+接下来的部分是关于 `time` 软件包提供的 `/usr/bin/time` 二进制可执行程序，而不是 shell 内建的 time 命令。
+
+### 软件包的语法
+
+一些 shells（例如 `bash` ）有一个内置的 `time` 命令，提供类似的关于时间和可能的其他资源的使用信息。
+
+要访问真正的命令，可能需要指定其路径名（类似于`/usr/bin/time`）。
+
+```shell
+time [options] command [arguments...]
+```
+
+### 软件包指令参数
 
-*   real时间是指挂钟时间，也就是命令开始执行到结束的时间。这个短时间包括其他进程所占用的时间片，和进程被阻塞时所花费的时间。
-*   user时间是指进程花费在用户模式中的CPU时间，这是唯一真正用于执行进程所花费的时间，其他进程和花费阻塞状态中的时间没有计算在内。
-*   sys时间是指花费在内核模式中的CPU时间，代表在内核中执系统调用所花费的时间，这也是真正由进程使用的CPU时间。

+### htop 安装
+
+在大多数的 Linux 发行版中你不会找到预安装的 `htop`，但作为最流行的实用程序之一，你会在几乎每个 Linux 发行版的默认存储库中找到 `htop`。
+
+因此，如果你的机器是基于 Debian/Ubuntu 驱动的，则以下命令应该可以完成你的工作：
+
+```shell
+sudo apt install htop
+```
+
+类似的，如果你使用的是 Fedora，则可以使用以下的命令：
+
+```shell
+sudo dnf install htop
+```
+
+如果你使用的是 CentOS 或 RedHat 则可以使用以下的命令：
+
+```shell
+sudo yum install htop
+```
+如果你想避免从源代码构建包，还有一个 Snap 包可用：
+
+```shell
+sudo snap install htop
+```
+
+如果你使用的是其它的发行版或者想从源代码构建，你可以使用 `wget` 下载并安装：
+这需要你下载并安装 `wget` `cmake`
+
+```shell
+wget https://link.zhihu.com/?target=https%3A//hisham.hm/htop/releases/2.2.0/htop-2.2.0.tar.gz
+
+tar -zxvf htop-2.2.0.tar.gz
+
+cd htop-2.2.0/
+
+./configure
+
+make
+
+make install
+```
+
+当然你也可以随时参考你可以随时参考 [htop 的 GitHub](https://link.zhihu.com/?target=https%3A//github.com/htop-dev/htop) 页面以获得详细说明。
+
+**说明**：htop源码安装方式默认安装到 `/usr/local` 目录下，如果想安装到其它路径，在执行 configure 时通过 `—prefix` 指定，格式为：`./configure --prefix=/some/path`

+测试主机之间网络的连通性(ipv6)
+
+## 补充说明
+
+**ping6命令** ping6 是 ICMPv6 版的 ping 实现。正确使用、访问 IPv6 网站需要您提前配置本地环境，选择支持 v6 的网站进行访问(ping)。
+执行 ping6 指令会使用 ICMPv6 传输(OSI)协议，发出要求回应的信息，若远端主机的网络功能没有问题，就会回应该信息，因而得知该主机运作正常。
+
+###  语法
+
+```bash
+ping6 (选项) (地址) [网络接口名称]
+```
+
+###  选项
+
+```bash
+-a [addrtype]: 生成 ICMPv6 节点信息节点地址查询;
+-b [bufsiz]: 设置套接字缓冲区大小;
+-c [count]: 在发送(和接收)ECHO_RESPONSE数据包后停止;
+-h [hoplimit]: 设置 IPv6 跳数限制;
+-I [interface]: 具有给定接口地址的源数据包;
+-i [wait]: 在发送每个数据包之间等待几秒钟，默认是 1 秒;
+-p [policy]: policy 指定要用于探测的 IPsec 策略;
+```
+###  地址
+
+目的主机：指定发送 ICMPv6 报文的目的主机。
+
+###  实例
+
+```bash
+$ ping6 -c4 ipw.cn

+
+### 服务器 IPv6 Ping 失败可能原因
+
+1. 服务器未开启 IPv6。
+2. 服务器已开启 IPv6，但防火墙(安全组)未对源地址是 IPv6 地址(::/0)的 ICMPv6 协议开放访问，

iostat的util参数解读有误。参照于man手册
Percentage of elapsed time during which I/O requests were issued to the device (bandwidth utilization for the device). Device saturation occurs when this value is close to 100% for  devices  serving  requests  serially.But  for  devices serving requests in parallel, such as RAID arrays and modern SSDs, this number does not reflect their performance limits.

 sed表达式可以使用单引号来引用，但是如果表达式内部包含变量字符串，就需要使用双引号。

+执行`pwck`命令后显示了一些警告，提示有用户`lp`的主目录 `/var/spool/lpd`不存在。为了解决这个问题，你有几个选项：
+1. 如果你确定这些用户不会被使用，你可以考虑使用`userdel`命令来删除这些用户。
+2. 如果这些用户需要被使用，你应该创建相应的目录。例如，你可以使用以下命令：
 
-
+```shell
+# 创建目录
+sudo mkdir /var/ftp
+# 将目录的所有权赋给相应的用户
+sudo chown ftp:ftp /var/ftp
+```
+3. 如果这些用户对应的软件包还未安装，你可以考虑安装它们。软件包管理器（如`yum`或`apt`）通常会自动创建必要的用户和目录。

+Docker
+==
+
+极为方便的容器软件。
+
+## 安装
+
+在 Linux 中输入以下命令安装 Docker。
+
+```bash
+# CentOS    参考：https://blog.csdn.net/zhaoyuanh/article/details/126610347
+#如果系统里有旧版本docker的话需要先行删除：
+sudo yum remove docker \
+                  docker-client \
+                  docker-client-latest \
+                  docker-common \
+                  docker-latest \
+                  docker-latest-logrotate \
+                  docker-logrotate \
+                  docker-engine
+
+#设置仓库：
+yum install -y yum-utils
+
+#添加Docker仓库：
+yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
+
+#安装Docker引擎(默认最新):
+yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
+
+#启动docker:
+sudo systemctl start docker
+
+```
+
+## 实例
+
+介绍几个常用场景：Docker Hub镜像市场相关，镜像仓库命令。
+
+1、下载docker hub镜像市场中的镜像。
+
+```bash
+docker pull user/image
+```
+
+2、在 docker hub 中搜索镜像。
+
+```bash
+# 注意需要下载镜像才能使用
+docker search search_word
+```
+
+3、向 docker hub 进行身份验证。
+
+```bash
+docker login
+```
+
+4、将镜像上传到 docker hub。
+
+```bash
+docker push user/image
+```
+

Subject: [PATCH 0807/1081] add(drm): modetest.md (#518)

* add(drm): modetest.md

* feat(drm): add compilation and installation example for modetest tool  ## Description  This commit adds an example for compiling and installing the modetest tool, which is used for testing and validating DRM (Direct Rendering Manager) driver functionality.  ## Compilation and Installation Example  Here is an example of how to compile and install the modetest tool:  1. Clone the modetest repository from the source:     ```shell    git clone https://github.com/dvdhrm/drm-tests.git    ```  2. Change into the modetest directory:     ```shell    cd drm-tests/modetest    ```  3. Install the necessary dependencies for compilation. This may vary depending on your distribution. For example, on Ubuntu, you can install the required packages using the following command:     ```shell    sudo apt-get install build-essential libdrm-dev    ```  4. Build the modetest tool:     ```shell    make    ```  5. Optionally, you can run the modetest tool directly from the build directory:     ```shell    ./modetest    ```  6. If you want to install the modetest tool system-wide, use the following command:     ```shell    sudo make install    ```     This will install the modetest binary into the appropriate system directories.  7. You can now run the modetest tool from anywhere on your system:     ```shell    modetest    ```  Please note that the compilation and installation process may vary depending on your system configuration and distribution. Make sure to follow the specific instructions provided by the modetest repository or consult the documentation for your distribution for more accurate and detailed instructions.

+reposync
+===
+
+同步yum存储库到本地目录
+
+## 概要
+
+```shell
+reposync [选项]
+```
+
+## 主要用途
+
+reposync用于将远程yum存储库同步到本地目录，使用yum检索包。
+
+## 选项
+
+```shell
+-h, --help
+# 显示帮助信息
+
+-c CONFIG, --config=CONFIG
+# 指定配置文件(默认为/etc/yum.conf)
+
+-a ARCH, --arch=ARCH
+# 指定arch
+
+--source
+# 同时下载src和rpm文件.
+
+-r REPOID, --repoid=REPOID
+# 指定要查询的repo id，可以指定多次(默认为全部启用)。
+
+-e CACHEDIR, --cachedir CACHEDIR
+# 存储元数据的目录。
+
+-t, --tempcache
+# 使用临时目录存储/访问yum-cache。
+
+-d, --delete
+# 删除存储库中不再存在的本地包。
+
+-p DESTDIR, --download_path=DESTDIR
+# 指定下载路径:默认为当前目录。
+
+--norepopath
+# 不要将重命名添加到下载路径中。只能在同步单个存储库时使用(默认是添加重命名)。
+
+-g, --gpgcheck
+# 下载后删除GPG签名检查失败的包。如果至少有一个包被删除，退出状态为“1”。
+
+-u, --urls
+# 只列出要下载的内容的url，不要下载。
+
+-l, --plugins
+# 启用yum插件支持。
+
+-m, --downloadcomps
+# 同时下载comps.xml。
+
+--download-metadata
+# 下载所有非默认元数据。
+
+-n, --newest-only
+# 每个repo只下载最新的包。
+
+-q, --quiet
+# 输出尽可能少的信息。
+
+--allow-path-traversal
+# 允许同步存储在repo目录之外的包。这些包是在元数据中通过使用绝对路径或上一级“..”系统引用的并且出于安全原因通常会在reposync中跳过。
+# 注意:使用此选项有潜在的安全隐患，因为通过提供恶意repodata，攻击者可以使reposync写入任意位置运行该文件系统的用户可以访问的文件系统。
+```
+
+## 例子
+
+```shell
+# 将'updates'仓库中的所有包同步到当前目录:
+reposync --repoid=updates
+
+# 只同步最新的包从'updates'仓库到当前目录:
+reposync -n --repoid=updates
+
+# 将'updates'和'extras'仓库中的包同步到当前目录:
+reposync --repoid=updates --repoid=extras
+
+# 将'updates'仓库中的所有包同步到repos目录:
+reposync -p repos --repoid=updates
+
+# 将'updates'仓库中的所有包同步到repos目录，排除x86_64架构文件。编辑/etc/yum.conf，添加选项exclude=*.x86_64。再执行:
+reposync -p repos --repoid=updates
+```
+
+## 文件
+
+reposync使用yum库来检索信息和包。如果没有指定配置文件，将使用默认的yum配置。
+
+*   /etc/yum.conf
+*   /etc/yum/repos.d/
+

+-n --includepkg
+# 通过命令行指定要纳入本地库中的包信息，需要提供URL或本地路径。
+
+-q --quiet
+# 安静模式执行操作，不输出任何信息。
+
+-g --groupfile <groupfile>
+# 指定本地软件仓库的组划分，示例：createrepo -g comps.xml /path/to/rpms
+# 注意：组文件需要和rpm包放置于同一路径下。
+
+-v --verbose
+# 输出详细信息。
+
+-c --cachedir <path>
+# 指定一个目录，用作存放软件仓库中软件包的校验和信息。
+# 当createrepo在未发生明显改变的相同仓库文件上持续多次运行时，指定cachedir会明显提高其性能。
+
+--basedir
+# Basedir为repodata中目录的路径，默认为当前工作目录。
+
+--update
+# 如果元数据已经存在，且软件仓库中只有部分软件发生了改变或增减，
+# 则可用update参数直接对原有元数据进行升级，效率比重新分析rpm包依赖并生成新的元数据要高很多。
+
+--skip-stat
+# 跳过--update上的stat()调用，假设如果文件名相同，则文件仍然相同(仅在您相当信任或容易受骗时使用此方法)。
+
+--update-md-path
+# 从这个路径使用现有的repodata来升级。
+
+-C --checkts
+# 不要生成回购元数据，如果它们的时间戳比rpm更新。如果您碰巧开启了该选项，则此选项将再次大幅减少处理时间一个未修改的回购，但它(目前)与——split选项互斥。注意:当包从repo中删除时，这个命令不会注意到。使用——update来处理这个。
+
+--split
+# 在拆分媒体模式下运行。与其传递单个目录，不如获取一组对应于媒体集中不同卷的目录。
+
+-p --pretty
+# 以整洁的格式输出xml文件。
+
+--version
+# 输出版本。
+
+-h --help
+# 显示帮助菜单。
+
+-d --database
+# 该选项指定使用SQLite来存储生成的元数据，默认项。
+
+--no-database
+# 不要在存储库中生成sqlite数据库。
+
+-S --skip-symlinks
+# 忽略包的符号链接
+
+-s --checksum
+# 选择repmed .xml中使用的校验和类型以及元数据中的包。默认值现在是“sha256”(如果python有hashlib)。旧的默认值是“sha”，它实际上是“sha1”，但是显式使用“sha1”在旧版本(3.0.x)的yum上不起作用，您需要指定“sha”。
+
+--profile
+# 输出基于时间的分析信息。
+
+--changelog-limit CHANGELOG_LIMIT
+# 只将每个rpm中的最后N个变更日志条目导入元数据
+
+--unique-md-filenames
+# 在元数据文件名中包含文件的校验和，有助于HTTP缓存(默认)
+
+--simple-md-filenames
+# 不要在元数据文件名中包含文件的校验和。
+
+--retain-old-md
+# 保留旧repodata的最新(按时间戳)N个副本(这样使用旧repodata .xml文件的客户端仍然可以访问它)。默认为0。
+
+--distro
+指定发行版标签。可以多次指定。可选语法，指定cpeid(http://cpe.mitre.org/)——distro=cpeid,distrotag
+
+--content
+# 指定关于存储库内容的关键字/标记。可以多次指定。
+
+--repo
+# 指定关于存储库本身的关键字/标签。可以多次指定。
+
+--revision
+# 存储库修订的任意字符串。
+
+--deltas
+# 告诉createrepo生成增量数据和增量元数据
+
+--oldpackagedirs PATH
+# 寻找更老的PKGS来对抗的路径。可以指定多次吗
+
+--num-deltas int
+# 要进行增量处理的旧版本的数量。默认为1
+
+--read-pkgs-list READ_PKGS_LIST
+# 使用——update将路径输出到PKGS实际读起来很有用
+
+--max-delta-rpm-size MAX_DELTA_RPM_SIZE
+# 要运行deltarpm的RPM的最大大小(以字节为单位)
+
+--workers WORKERS
+# 为读取RPMS而生成的工作线程数
+
+--compress-type
+# 指定要使用的压缩方法:compat(默认)，xz(可能不可用)，gz, bz2。

+
+## 返回值
+
+返回状态为成功除非给出了非法选项或非法参数。
+
+## 例子
+
+```shell

+sshpass
+===
+
+免交互 SSH 登录工具。
+
+## 补充说明
+
+免交互 SSH 登录工具，但不要用在生产服务器上。
+
+如果你想自动在 SSH 登录提示符中提供**密码**和**用户名**怎么办？这时 **sshpass** 就可以帮到你了。
+
+**sshpass** 是一个简单、轻量级的命令行工具，通过它我们能够向命令提示符本身提供密码（非交互式密码验证）。
+
+### 安装
+
+```shell
+# RedHat/CentOS
+yum install sshpass
+
+# Debian/Ubuntu
+apt-get install sshpass
+```
+
+###  语法
+
+```shell
+sshpass (选项)
+```
+
+###  选项
+
+```shell
+用法: sshpass [-f|-d|-p|-e] [-hV] 命令 参数
+    -f 文件名     从文件中获取密码

 ###  二维、多维数组使用 
 
-awk的多维数组在本质上是一维数组，更确切一点，awk在存储上并不支持多维数组。awk提供了逻辑上模拟二维数组的访问方式。例如，`array[2,4]=1`这样的访问是允许的。awk使用一个特殊的字符串`SUBSEP(�34)`作为分割字段，在上面的例子中，关联数组array存储的键值实际上是2�344。
+awk的多维数组在本质上是一维数组，更确切一点，awk在存储上并不支持多维数组。awk提供了逻辑上模拟二维数组的访问方式。例如，`array[2,4]=1`这样的访问是允许的。awk使用一个特殊的字符串`SUBSEP(\034)`作为分割字段，在上面的例子中，关联数组array存储的键值实际上是2\0344。
 
 类似一维数组的成员测试，多维数组可以使用`if ( (i,j) in array)`这样的语法，但是下标必须放置在圆括号中。类似一维数组的循环访问，多维数组使用`for ( item in array )`这样的语法遍历数组。与一维数组不同的是，多维数组必须使用`split()`函数来访问单独的下标分量。

-将`/home/Blinux/html/`这个目录下所有文件和文件夹打包为当前目录下的html.zip：
+压缩单个文件，这会将 `file.txt` 文件压缩到名为 `compressed.zip` 的归档文件中
+
+```shell
+zip compressed.zip file.txt
+```
+
+压缩多个文件，下面这个命令会把 `file1.txt`，`file2.txt`，和 `file3.txt` 压缩到一个叫做 `compressed.zip` 的归档文件中。
+
+```shell
+zip compressed.zip file1.txt file2.txt file3.txt
+```
+
+压缩整个目录，下面这个命令 `-r` 参数表示递归压缩，该命令将压缩 `folder` 目录及其所有子目录和文件
+
+```shell
+zip -r compressed.zip folder/
+```
+
+使用最大压缩比压缩文件，下面这个命令 `-9` 参数指定了最大压缩比，尽管可能需要更长的处理时间
+
+```shell
+zip -9 compressed.zip file.txt
+```
+
+创建密码保护的 zip 文件，下面这个命令 `-e` 参数会提示用户输入密码以创建加密的 zip 文件。
+
+```shell
+zip -e secure.zip file.txt
+```
+
+只压缩新文件或已更改的文件，如果 `compressed.zip` 已存在，`-u` 参数会更新归档中的 `file.txt` 或将其添加至归档中（如果它是新的）
+
+```shell
+zip -u compressed.zip file.txt
+```
+
+压缩文件但不保留目录结构，`-j` 参数将不保留 `file.txt` 的父目录 `folder`，文件在 zip 中的位置将是在根目录下
+
+```shell
+zip -j compressed.zip folder/file.txt
+```
+
+将`/home/Blinux/html/`这个目录下所有文件和文件夹打包为当前目录下的 `html.zip`：
 
 ```shell
 zip -q -r html.zip /home/Blinux/html

-将PCAP包重新发送，用于性能或者功能测试
+将保存在 PCAP 文件包重新发送，用于性能或者功能测试
 
 ## 补充说明
 
-简单的说， **tcpreplay** 是一种pcap包的重放工具，它可以将用ethreal、wireshark工具抓下来的包原样或经过任意修改后重放回去。它允许你对报文做任意的修改（主要是指对2层、3层、4层报文头），指定重放报文的速度等，这样tcpreplay就可以用来复现抓包的情景以定位bug，以极快的速度重放从而实现压力测试。
+`tcpreplay` 用于重放保存在 pcap 文件中的网络流量，它支持按照捕获 pcap 文件时数据包的速度、或者指定速度去重放网络流量，只要在硬件承受的范围内即可。
 
-###  选项
+它可以根据需要，使流量可以在两个网卡直接拆分、写入文件、进行筛选、以各种方式进行编辑，从而为测试防火墙、NIDS和其他网络设备提供了方法。

--A "<args>" 在使用 tcpdump 风格打印输出信息时，同时再调用tcpdump中的参数， 默认已经带有“-n,-l”，所以一般看到的都是ip地址，而没有主机名的打印，注意这个是在tcpreplay使用了-v参数时才能使用，不带-v不会报错，但是没有实际意义。格式：-vA “nnt”表示以tcpdump风格输出报文信息，并且不打印时间戳、主机名、端口服务名称。注意不要使用-c参数来指定打印的数据报文的个数，这样发送出去的报文也会变少。
--c <cachefile> 双网卡回放报文必选参数，后面紧跟cache文件名，该文件为tcpprep根据对应的pcap文件构造出来。 
--D 把应用层的数据，使用dump mode写入到指定文件中去，和-w、-W 参数一起使用。 
--e <ip1:ip2> 指定端点的ip，即把发送报文的和接收的报文的ip都修改称对应的参数值中指定的ip，但是这样发送的出的报文不会区分client和server。。 
--f <configfile> 指定配置文件。
--F 在发送报文时，自动纠正错误的校验和。对测试DUT的校验和检验。
--h 显示帮助文件。 
--i <nic> 双网卡回放报文必选参数，指定主接口。
--I <mac> 重写主网卡发送出报文的目的MAC地址。 
--j <nic> 双网卡回放报文必选参数，指定从接口。
--J <mac> 重写从网卡发送出报文的目的MAC地址。 
--k <mac> 重写主网卡发送报文的源MAC地址。 
--K <mac> 重写从网卡发送报文的源MAC地址。
--l <loop> 指定循环的次数。
-    --loopdelay-ms=2000 每次循环间隔2000毫秒。
--L <limit> 指定最大的发包数量。可以在确认连接的调试时使用。 
--m <multiple> 指定一个倍数值，就是必默认发送速率要快多少倍的速率发送报文。 加大发送的速率后，对于DUT可能意味着有更多的并发连接和连接数，特别是对于BT报文的重放， 因为连接的超时是固定的，如果速率增大的话， 留在session表中的连接数量增大，还可以通过修改连接的超时时间来达到该目的。
--M 表示不发送“火星”的ip报文，man文件中的定义是 0/8、172/8、 255/8。
--n 在使用-S参数，不对混杂模式进行侦听。
--N <CIDR1:CIDR2,...> 通过伪造的NAT，重写IP地址。这个参数应该有很重要的应用，目前没有测试使用。
--O 没有测试使用。
--p <packetrate> 指定每秒发送报文的个数，指定该参数，其它速率相关的参数被忽略，最后的打印信息不会有速率和每秒发送报文的统计。
--P 表示在输出信息中打印PID的信息，用于单用户或单帐户模式下暂停和重启程序。
--r <rate> 指定发送的速率。目前-m/-r/-p这3个参数的相互关系。
--R 让网卡极限速度发数据包。 
--t <mtu> 指定MTU，标准的10/100M网卡的默认值是1500。 
--T Truncate packets > 截去报文中MTU大于标准值的部分再发送出去，默认是不发送，skip掉。
--v 每发送一个报文都以 tcpdump 的风格打印出对应的信息。
--V 查看版本号。
--w <file> 将主网卡发送的报文写入一个文件中，参数后紧跟文件名。

+
+`--maxsleep=number`
+
+设置数据包之间休眠不超过X毫秒。此选项将整数作为参数。此选项的默认输入number为：0
+设置tcpreplay在数据包之间休眠的最大毫秒数限制。有效防止数据包之间的长时间延迟，而不会影响大多数数据包。默认为禁用。
+
+`-v, --verbose`
+
+通过tcpdump将解码后的数据包打印到标准输出。此选项最多可出现1次
+
+`-A string, --decode=string`
+
+传递给tcpdump解码器的参数。此选项最多可出现1次。此选项必须与-v参数以前使用。
+当启用详细模式（-v）时，您还可以指定一个或多个附加参数以传递给tcpdump来修改数据包的解码方式。默认情况下，使用-n和-l。确保string用双引号引起来，如：-A“-axxx”，否则会被tcpreplay作为参数误用。有关选项的完整列表，请参见tcpdump(1)手册页
+
+`-K, --preload-pcap`
+
+在发送之前将数据包预加载到RAM中。
+此选项在开始发送之前将指定的pcap加载到RAM中，以便提高启动性能，进而提高重放性能。预加载可以使用或不使用--loop。此选项还会控制每次迭代的流统计信息收集，这可以显着减少内存使用量。基于所提供的选项和从第一循环迭代收集的统计来预测流(flow)统计。
+
+`-c string, --cachefile=string`
+
+通过tcpprep缓存(cache)文件拆分流量。此选项最多可出现1次。此选项必须与以下选项一起使用：intf2。此选项不得与以下选项一起使用：dualfile。
+如果你有一个pcap文件，你想用它来通过一个设备（防火墙，路由器，IDS等）发送双向流量，然后使用tcpprep你可以创建一个缓存文件，tcpreplay将用它来分割两个网络接口的流量。 
+
+`-2, --dualfile`
+
+从 network tap  一次重放两个文件。此选项最多可出现1次。此选项必须与以下选项一起使用：intf2。此选项不得与以下任项一起使用：cachefile。
+如果您使用网络分流器捕获网络流量，那么您最终可以获得两个pcap文件 - 每个方向一个。此选项将同时重放这两个文件，每个接口一个，并使用每个文件中的时间戳混合它们
+
+`-i string, --intf1=string`
+
+客户端到 server/RX/primary(主要) 流量输出接口。该选项最多可出现 1 次。
+用于发送所有流量或通过 tcpprep 标记为 "primary" 流量的所需网络接口。primary 流量通常是客户端到服务器或 khial 虚拟接口上的入站（RX）流量。
+
+`-I string, --intf2=string`
+
+服务器到 client/TX/secondary(辅助) 流量输出接口。该选项最多可能出现 1 次。
+
+用于发送通过 tcpprep 标记为 “secondary” 流量的可选网络接口。辅助(secondary)流量通常是服务器到客户端或 khial 虚拟接口上的出站 (TX)。一般来说，只有将此选项与 --cachefile 一起使用才有意义。
+
+`--listnics`
+
+列出所有可用的网卡并退出。
+
+`-l number, --loop=number`
+
+循环捕获文件X次。此选项最多可出现1次。此选项将整数作为输入参数。 number的值被限制为：
+大于或等于0，此选项的默认输入number为：1
+
+`--loopdelay-ms=number`
+
+循环之间的延迟（以毫秒为单位）。此选项必须与以下选项一起出现：--loop。此选项将整数作为输入参数。 number的值被限制为：大于或等于0，此选项的默认输入number为：0
+
+`--pktlen`
+
+覆盖snaplen并使用实际的数据包len。此选项最多可出现1次。
+默认情况下，tcpreplay将根据pcap文件中存储的“snaplen”的大小发送数据包，这通常是正确的做法。但是，偶尔，工具会存储更多的字节。通过指定此选项，tcpreplay将忽略snaplen字段，而是尝试根据原始数据包长度发送数据包。如果指定此选项，可能会发生错误。
+
+`-L number, --limit=number`
+
+限制要发送的数据包数量。此选项最多可出现1次。此选项将整数作为输如参数。 number的值被限制为：大于或等于1，此选项的默认输如number为：-1
+默认情况下，tcpreplay将发送所有数据包。或者手工指定要发送的最大数据包数。
+
+`--duration=number`
+
+限制发送的秒数。此选项最多可出现1次。此选项将整数作为输入参数。 number的值被限制为：大于或等于1，此选项的默认number为：-1
+默认情况下，tcpreplay将发送所有数据包。或者手工指定要传输的最大秒数。
+
+`-x string, --multiplier=string`
+
+将重放速度修改为指定倍数。此选项最多可出现1次。此选项不得与以下任何选项一起出现：pps，mbps，oneatatime，topspeed。
+指定一个值以修改数据包重放速度。例子：
+2.0：将以捕获速度的两倍重放流量
+0.7：将以捕获的速度的70％重放流量
+
+`-p string, --pps=string`
+
+以给定的packets/sec重放数据包。此选项最多可出现1次。此选项不得与以下任何选项一起出现：multiplier, mbps, oneatatime, topspeed.。
+指定一个值以将数据包重放调整为特定的packets/sec速率。例子：
+200：将以每秒200个数据包重放流量
+0.25：将以每分钟15个数据包重放流量
+
+`-M string, --mbps=string`
+
+以给定的Mbps重放数据包。此选项最多可出现1次。此选项不得与以下任何选项一起出现：multiplier，pps，oneatatime，topspeed。
+可为tcpreplay设定其发送数据包的Mbps速率，该值可以指定为浮点值
+
+`-t, --topspeed`
+
+尽可能快地重放数据包。此选项不得与以下任何选项一起出现: mbps, multiplier, pps, oneatatime.
+
+`-o, --oneatatime`
+
+根据用户输入重放每个数据包。此选项不得与以下任何选项一起出现：mbps，pps，multiplier，topspeed。
+允许您一次单步执行一个或多个数据包。 
+
+`--pps-multi=number`
+
+指定每个时间间隔要发送的数据包数。此选项必须与以下选项一起使用：pps。此选项将整数作为输入参数。 number的值被限制为：大于或等于1，此选项的默认值为：1
+当尝试以非常高的速率发送数据包时，每个数据包之间的时间可能很短，以至于不可能在所需的时间段内准确地休眠。此选项允许您一次发送多个数据包，从而允许更长的睡眠时间，这可以更准确地实现。
+
+`--unique-ip`
+
+修改每个循环迭代的IP地址以生成唯一流。此选项必须与以下选项一起使用：loop。
+确保每个--loop迭代的IPv4和IPv6数据包都是唯一的。这是以不会改变数据包CRC的方式完成的，因此通常不会影响性能。此选项将显着增加多次循环迭代生成的flow/sec。
+
+`--unique-ip-loops=string`
+
+分配新的唯一 IP 之前的 --loop 迭代次数。默认值为 1。假定同时使用 --loop 和 --unique-ip。
+
+`--netmap`
+
+将数据包直接写入启用netmap的网络适配器。
+此功能将检测Linux和BSD系统上支持netmap的网络驱动程序。如果检测到，则会在执行期间绕过网络驱动程序，并直接写入网络缓冲区。这将允许您在商用网络适配器上实现全线速率，类似于商用网络流量生成器实现的速率。请注意，绕过网络驱动程序将中断通过测试接口连接的其他应用程序。
+
+还可以通过将接口指定为`netmap:<intf>`或 `vale:<intf>` 来启用此功能。例如，`netmap:eth0` 指定接口 eth0 上的网络映射。
+
+`--nm-delay=number`
+
+Netmap启动延迟。此选项将整数作为参数。此选项的默认输入为：10
+加载netmap后延迟的秒数。在netmap传输之前确保接口完全开启工作。需要netmap选项。默认值为10秒。
+
+`--no-flow-stats`
+
+阻止打印和跟踪流量，速率和到期
+
+禁止收集和打印流量统计信息。 不使用--preload-pcap选项时，此选项可以提高性能，否则它的唯一功能是禁止打印。
+
+流功能将跟踪和打印正在发送的流的统计信息。 简单来讲，一个流是由5元组进行唯一区分的，即源IP、目的IP、源端口、目的端口和协议。
+如果指定了--loop，则从一次迭代到下一次迭代的流将不是唯一的，除非数据包被更改。 使用--unique-ip或tcpreplay-edit在迭代之间更改数据包。 
+
+`--flow-expiry=number`
+
+流被视为过期前的非活动秒数。此选项不得与以下选项一起使用：no-flow-stats。此选项将整数作为输入参数。 number的值被限制为：大于或等于0
+此选项的默认值为：0
+此选项将根据流的idle time来跟踪和报告流的过期。 pcap文件中的时间戳用于确定到期时间，而不是重放数据包的实际时间戳。例如，值30表示如果流上没有流量持续30秒，则任何后续流量都将被视为新流量，从而将增加流量和每秒流量（fps）统计量。
+
+（例如，值 30 表示如果某个流在 30 秒内没有看到任何流量，则任何后续流量都将被视为新流，从而增加流量和每秒流量 (fps) 统计数据。）
+
+此选项可用于优化流产品的流超时设置。当实际流量响应速度很慢时，将超时设置较低可能会导致流量被丢弃。将流量超时配置得过高可能会增加流量产品所需的资源。
+请注意，在高于原始速度的重放时使用此选项可能会导致流量和fps计数膨胀。
+默认值为0（无到期），典型值为30-120秒
+
+`-P, --pid`
+
+在启动时打印tcpreplay的PID
+
+`--stats=number`
+
+每X秒打印统计信息，如果为'0'则打印每个循环。此选项将整数作为输入参数。number 的值被限制为：大于或等于 0
+
+请注意，定时延迟是"best effort"，发送数据包之间的长延迟可能会导致打印统计数据之间同样长的延迟。
+
+`-V, --version`
+
+打印版本信息
+
+`-h, --less-help`
+
+打印简单的帮助信息
+
+`-H, --help`
+
+打印帮助信息
+
+`-!, --more-help`
+
+打印详细帮助信息
+
+`--save-opts [=cfgfile]`
+
+将选项状态保存到cfgfile。默认值是下面的OPTION PRESETS章节中列出的最后一个配置文件。该命令在更新配置文件后退出。
+
+`--load-opts=cfgfile, --no-load-opts`
+
+从 cfg 文件加载选项。 no-load-opts 形式将禁止加载早期的 config/rc/ini 文件。`--no-load-opts` 提前处理，无序。

+column
+===
+
+按列格式化输出文件
+
+## 概要
+
+```shell
+column [options] [file ...]
+```
+
+## 主要用途
+
+- 将单列数据整理为多列显示，每行宽度可以指定，超出的部分自动换行。
+- 将多列数据进行快速整理，对齐每列的字符。
+
+## 参数
+
+file（可选），当没有指定文件时，默认会从标准输入读取，因此可以配合管道符使用。
+
+## 选项
+
+```shell
+-c, --columns <width>           输出宽度（以字符数表示）
+-t, --table                     创建一个表格（每列字符会对齐）
+-s, --separator <string>        指定识别表格的分隔符
+-o, --output-separator <string> 输出表格的列分隔符，默认为两个空格
+-x, --fillrows                  在列之前填充行
+-h, --help                      显示此帮助
+-V, --version                   输出版本信息
+```
+
+## 返回值
+
+格式化排列后的字符串。
+
+## 示例
+
+- 整理单列数据
+
+```shell
+# 生成 26 个英文字母， 每列一个
+$ for a in {a..z}; do echo $a; done > test
+
+# 每行最大 60 个字符
+$ cat test | column -c 60
+a       e       i       m       q       u       y
+b       f       j       n       r       v       z
+c       g       k       o       s       w
+d       h       l       p       t       x
+
+# 在上面的基础上，进一步整理，每列之间宽度默认两个空白符
+$ cat test | column -c 60 | column -t
+a  e  i  m  q  u  y
+b  f  j  n  r  v  z
+c  g  k  o  s  w
+d  h  l  p  t  x
+
+# 指定每列之间用 ', ' 拼接
+$ cat test | column -c 60 | column -t -o ', '
+a, e, i, m, q, u, y
+b, f, j, n, r, v, z
+c, g, k, o, s, w
+d, h, l, p, t, x
+```

+
+## 安装
+
+Pip 是 Python 的包管理工具，通常随着 Python 的安装一起安装。确保你的 Python 版本是 3.4 或更高版本。
+
+```bash
+# Ubuntu系统
+sudo apt install python3-pip
+```
+```badh
+# CentOS
+sudo yum install python3-pip
+```
+如果需要更新 Pip，可以运行以下命令：
+
+```bash
+python -m pip install --upgrade pip
+```
+
+## 安装包
+
+通过 Pip 安装 Python 包非常简单。使用以下命令：
+
+```bash
+pip install <package_name>
+```
+
+例如，安装一个名为 `requests` 的包：
+
+```bash
+pip install requests
+```
+
+## 卸载包
+
+要卸载已安装的包，使用以下命令：
+
+```bash
+pip uninstall package_name
+```
+
+例如，卸载 `requests` 包：
+
+```bash
+pip uninstall requests
+```
+
+## 查看已安装的包
+
+你可以使用以下命令查看当前环境中已安装的所有包及其版本：
+
+```bash
+pip list
+```
+
+## 导出和导入依赖关系
+
+使用 `pip freeze` 命令可以将当前环境中的所有包及其版本导出到一个文本文件，通常命名为 `requirements.txt`：
+
+```bash
+pip freeze > requirements.txt
+```
+
+要在另一个环境中安装相同的依赖，可以使用以下命令：
+
+```bash
+pip install -r requirements.txt
+```
+
+## 安装特定版本的包
+
+如果需要安装特定版本的包，可以在包名后面添加版本号：
+
+```bash
+pip install package_name==1.2.3
+```
+
+## 搜索包
+
+要搜索可用的 Python 包，可以使用 `pip search` 命令：
+
+```bash
+pip search package_name
+```
+
+## 安装开发版本
+
+有时你可能需要安装包的开发版本。通常，开发版本存储在版本控制系统中（如 GitHub）：
+
+```bash
+pip install git+https://github.com/user/repo.git
+```
+
+这将安装存储库的最新版本。
+
+以上是一些常用的 Pip 命令，希望这个简要教程能够帮助你更好地使用 Python 包管理工具。

+===
+
+管理iSCSI连接
+
+## 补充说明
+
+**iscsiadm命令** 用于管理 iSCSI（Internet Small Computer System Interface）存储连接。iSCSI 是一种基于网络的存储协议，允许在计算机之间传输块级别的数据。iscsiadm 命令提供了与 iSCSI 存储设备进行连接、配置和管理的功能。
+```shell
+yum install iscsi-initiator-utils   #安装iscsiadm
+/etc/iscsi/initiatorname.iscsi      #iscsi启动器名称配置文件位置
+systemctl enable iscsi              #设置服务开机启动
+systemctl enable iscsid             
+systemctl restart iscsi             #重启iscsi服务
+systemctl restart iscsid           
+```
+
+### 语法
+
+```shell
+iscsiadm [选项] <命令> <参数>
+```
+
+### 选项
+
+```shell
+-m，--mode         # <模式> 指定工作模式，如discovery（发现模式）、node（管理节点）、session（管理会话）、discoverydb、host、iface（管理 iSCSI 网络接口）；
+-t，--type         # 指定类型，如sendtargets (或st)、isns、fw，仅用于discovery模式；
+-T，--targetname   # 指定目标名称，仅用于node模式；
+-p，--portal       # <ip:port> 指定目标IP,不带端口默认使用3260，仅用于discovery、node模式；
+-l，--login        # 登录一个iSCSI设备，仅用于discovery、node模式；
+-u，--logout       # 退出一个iSCSI设备，仅用于node、session模式；
+-I，--interface    # 指定用于iSCSI操作的网络接口；
+-P，--print        # <0-4> 打印详细，用于discovery、node、session模式；
+-s，--stats        # 查看会话状态
+-h，--help         # 显示帮助；
+-V，--version      # 显示版本信息。
+```
+
+### 实例
+
+发送iSCSI发现请求，并列出发现的iSCSI设备目标器：
+
+```shell
+[root@Azroy-s1 ~]# iscsiadm -m discovery -t st -p 10.10.10.10
+10.10.10.10:3260,1 iqn.2000-01.com.synology:NAS.default-target.1
+```
+
+登录到发现的iSCSI目标器：
+
+```shell
+[root@Azroy-s1 ~]# iscsiadm -m node -T iqn.2000-01.com.synology:NAS.target.1 -p 10.10.10.10 -l
+Logging in to [iface: default, target: iqn.2000-01.com.synology:NAS.target.1, portal: 10.10.10.10,3260] (multiple)
+Login to [iface: default, target: iqn.2000-01.com.synology:NAS.target.1, portal: 10.10.10.10,3260] successful.
+```
+
+查看已登录的设备：
+
+```shell
+[root@Azroy-s1 ~]# iscsiadm -m session
+tcp: [3] 10.10.10.10:3260,1 iqn.2000-01.com.synology:NAS.target.1 (non-flash)
+```
+
+退出已登录的设备：
+
+```shell
+[root@Azroy-s1 ~]# iscsiadm -m node -T iqn.2000-01.com.synology:NAS.target.1 -p 10.10.10.10 -u
+Logging out of session [sid: 11, target: iqn.2000-01.com.synology:NAS.target.1, portal: 10.10.10.10,3260]
+或
+[root@Azroy-s1 ~]# iscsiadm -m session -u   #退出所有iscsi会话
+```
+
+使用lsblk或fdisk查看硬盘，对硬盘分区再格式化后可挂载目录
+

+`mtr`结合了`traceroute`和`ping`程序的功能，是一款简单的网络诊断工具。  
+用于调查 mtr 运行的主机与用户指定的目标主机之间的网络连接。在确定机器之间每个网络跳转的地址后，它会向每台机器发送一系列 ICMP ECHO 请求，以确定与每台机器的链路质量。在此过程中，它会打印每台机器的运行统计数据。

+-w      限制输出宽度，默认为 '80'
+-c      居中显示
+-f      指定字体，默认为 'standard'
+-k      保留字符之间的空隙
+-t      对齐宽度到当前终端的宽度，这个参数优先级比 -w 高
+-v      显示版本信息
+```
+
+## 返回值
+
+字符串，由简单字符拼接而成的 “字画符”。
+
+## 示例
+
+- 从参数输入

+  每个数字代表不同的权限集合，分别为：
+
+  - 第一个数字`7`：所有者（user）的权限
+  - 第二个数字`5`：所属组（group）的权限
+  - 第三个数字`5`：其他用户（others）的权限
+

+
+  因此，`755`的具体权限为：
+
+  - `7`（所有者）= 4 (读) + 2 (写) + 1 (执行) = 7

 在指定目录下查找文件
 
+## 解释
+
+从每个指定的起始点 (目录) 开始，搜索以该点为根的目录树，并按照运算符优先级规则**从左至右**评估给定的表达式，直到结果确定，此时`find`会继续处理下一个文件名。
+
 ## 补充说明
 
-**find命令** 用来在指定目录下查找文件。任何位于参数之前的字符串都将被视为欲查找的目录名。如果使用该命令时，不设置任何参数，则find命令将在当前目录下查找子目录与文件。并且将查找到的子目录和文件全部进行显示。
+本文列出的选项指的是**表达式列表中的选项**。这些选项控制了`find`的行为，需在**最后一个路径名之后**立即指定。
 
-### 语法
+五个真实选项: `-H、-L、-P、-D 和 -O`。如果出现，**必须位于第一个路径名之前**。关于这部分内容本文不做描述，具体内容可参考[man7.org中的find](https://man7.org/linux/man-pages/man1/find.1.html#top_of_page)
 
+如果使用该命令时，不设置任何参数，则`find`命令将在当前目录下查找子目录与文件，并且将查找到的子目录和文件全部进行显示。等效于以下命令:
 ```shell
-find(选项)(参数)
+find . -print
 ```
 
-### 选项
+## 语法
+
+```shell
+find [-H] [-L] [-P] [-D debugopts] [-Olevel] [起始点...] [表达式]
+```
 
+忽略真实选项后 (更为常见): 
+```shell
+find [起始点...] [表达式]
+```
+
+## 表达式分类
+起始点（列表）之后的部分是表达式。这是一种**查询规范**，描述了我们如何匹配文件（返回**真**或者**假**）以及对匹配到的文件进行何种操作。表达式由一系列元素组成：
+- 测试（Tests）：测试返回一个真或假值，通常基于我们正在考虑的文件的某个属性。例如，`-empty`测试仅在当前文件为空时为真。
+- 操作（Actions）：操作具有副作用（例如在标准输出上打印内容），并返回真或假，通常基于它们是否成功。例如，`-print`操作会在标准输出上打印当前文件的名称。
+- 全局（Global）：全局选项影响命令行中任何部分指定的测试和操作的执行。全局选项始终返回真值。例如，`-depth`选项使find以深度优先的顺序遍历文件系统。
+- 位置（Positional）：位置选项仅影响其后的测试或操作。位置选项始终返回真值。例如，`-regextype`选项是位置选项，用于指定命令行中后续正则表达式所使用的正则表达式方言。
+- 操作符（Operators）：运算符将表达式中的其他项连接起来。例如，它们包括`-o`（表示逻辑或）和`-a`（表示逻辑与）。如果缺少运算符，则默认使用`-a`。

-### 参数
+### 操作选项
+
+#### -delete 删除文件或目录。
+> :warning:警告：find 命令会将命令行作为表达式进行解析，因此将`-delete`放在首位会将指定的起始点下的**所有内容删除**。且`-delete`操作无法删除一个目录，除非它是空的。
+
+##### *无参数*
+
+##### 描述
+如果删除成功则返回真。若删除失败，将显示错误消息，并且 find 最终退出时的状态码将为非零。
+
+##### 相关选项
+- **-depth**：在命令行中使用`-delete`操作会自动启用`-depth`选项。为了避免意外情况，通常最好在早期的**Tests选项**中**明确使用**`-depth`选项。
+- **-prune**：由于`-depth`会使`-prune`失效，因此`-delete`操作无法与`-prune`有效结合使用。通常，用户可能希望在实际删除操作前，先用带有`-print`的查找命令行进行测试，以确保在添加`-delete`进行实际删除时不会出现意外结果。
+- **-ignore_readdir_race**：`-delete`与此选项一起使用时，find 会忽略自父目录读取以来文件已消失的情况下`-delete`操作的错误：它不会输出错误诊断，不会将退出代码更改为非零，并且`-delete`操作的返回代码将为真。
+
+#### -exec 执行命令
+
+> :warning:警告：使用`-exec`操作存在不可避免的安全问题，应改用`-execdir`选项。
+
+##### 参数
+`command ;` 或 `command {} +`
+
+##### 描述
+如果返回状态为 0，则结果为真。**注意**：find 命令会将**所有后续参数**视为`command`的参数，直到遇到包含`;`的参数为止。字符串`{}`会在`command`的参数中所有出现的位置被替换为当前正在处理的文件名，而不仅仅是在它单独出现的参数中，这与某些版本的 find 不同。这两种结构可能需要使用反斜杠`\`或引号来转义，以防止被 shell 扩展。指定的命令会为每个匹配的文件运行一次。命令在起始目录中执行。
+
+#### -execdir 在包含匹配文件的子目录中执行命令
+
+##### 参数
+`command ;` | `command {} +`
+
+##### 描述
+类似于`-exec`，但指定的`command`会在包含匹配文件的**子目录中运行**，而非find的起始点目录。与`-exec`一样，如果从shell调用find，`{}`应加引号。这是一种更安全的调用`command`方式，因为它避免了在解析匹配文件路径时出现的竞争条件。与`-exec`操作类似，`+`形式的`-execdir`会构建一个命令行来处理多个匹配文件，但任何给定的`command`调用只会列出存在于同一子目录中的文件。如果使用此选项，必须确保 PATH 环境变量未引用`.`，否则攻击者可以通过在您将运行`-execdir`的目录中留下一个适当命名的文件来运行任何命令。同样，PATH 中的条目**不应为空**或**非绝对目录名**。如果使用`+`形式的任何调用以非零值作为退出状态返回，则 find 也会返回非零退出状态。如果 find 遇到错误，有时会导致立即退出，**因此某些待处理的command可能根本不会运行**。 操作结果取决于使用的是`+`还是`;`变体。`-execdir command {} + `总是返回真，而  `-execdir command {} ;`仅在命令返回 0 时返回真。
+
+#### -fls 创建文件并将结果写入文件
+
+##### 参数
+`file`
+
+##### 描述
+此选项始终返回真。`-fls`类似于`-ls`和`-fprint`，但`-fls`会将结果写入文件中。无论谓词是否匹配，输出文件始终会被创建。有关文件名中特殊字符处理的信息，请参阅“特殊文件名处理”部分。
+
+#### -fprint 将完整文件名打印到指定文件中
+
+##### 参数
+`file`
+
+##### 描述
+此选项始终返回真。若运行 find 时`file`不存在，则创建该`file`；若`file`已存在，则截断其内容。文件名`/dev/stdout`和`/dev/stderr`有特殊处理，分别指向标准输出和标准错误输出。即使谓词从未匹配，输出文件也会始终创建。
+
+#### -fprint0
+
+##### 参数
+`file`
+
+##### 描述
+此选项始终返回真。类似于`-print0`，但将输出写入文件；类似于`-fprint`。即使谓词从未匹配，输出文件也始终会被创建。
+
+#### -fprintf
+
+##### 参数
+`file`
+
+##### 描述
+此选项始终返回真。类似于`-printf`，但将输出写入文件；类似于`-fprint`，即使谓词从未匹配，输出文件也会始终创建。
+
+#### -ls 列出当前文件并输出到标准输出
+
+##### *无参数*
+
+##### 描述
+此选项始终返回真。以`ls -dils`格式列出当前文件并输出到标准输出。块计数为 1 KB 块，除非设置了环境变量 POSIXLY_CORRECT，此时使用 512 字节块。
+
+#### -ok 执行命令前询问用户
+
+##### 参数
+`command ;`
+
+##### 描述
+类似于`-exec`，但首先会询问用户。如果用户同意，则运行该命令；否则仅返回 false。若运行该命令，其标准输入将被重定向至`/dev/null`。对提示的响应会与一对正则表达式进行匹配，以确定其为肯定或否定回答。若设置POSIXLY_CORRECT 环境变量，则该正则表达式从系统获取；否则，从 find 的消息翻译中获取。如果系统没有合适的定义，将使用 find 自身的定义。无论哪种情况，正则表达式本身的解释都会受到环境变量 LC_CTYPE（字符类）和 LC_COLLATE（字符范围和等价类）的影响。
+
+##### 相关选项
+- **-files0-from**：不能与`-ok`同时指定。
+
+#### -okdir
+
+##### 参数
+`command ;`
+
+##### 描述
+类似于`-execdir`，但在执行前会以与`-ok`相同的方式询问用户。如果用户不同意，则直接返回 false。如果命令被执行，其标准输入将从`/dev/null`重定向。
+
+##### 相关选项
+- **-files0-from**：不能与`-okdir`同时指定。
+
+#### -print 打印完整文件名，后跟一个换行符
+
+##### *无参数*
+
+##### 描述
+此选项始终返回真。如果你将 find 的输出通过管道传输到另一个程序，并且你正在搜索的文件可能包含换行符，那么应该考虑使用`-print0`而不是`-print`。
+
+#### -print0 打印完整文件名，后跟一个空字符
+
+##### *无参数*
+
+##### 描述
+此选项始终返回真。包含换行符或其他类型空白字符的文件名能被正确解析，以便处理 find 输出的程序能正确理解。此选项对应于`xargs`的`-0`选项。
+
+#### -printf 打印格式
+
+##### 参数
+`format`
+
+可用的转义字符和指令包括：
+- \a 警报。
+- \b 退格键。
+- \c 立即停止打印并清空输出。
+- \f 换页。
+- \n 换行。
+- \r 回车符。
+- \t 水平制表符。
+- \v 垂直制表符。
+- \0 空字符。
+- \\\ 一个字面的反斜杠`\`。
+- \NNN 字符，其 ASCII 码为 NNN（八进制）。
+- A 一个反斜杠字符`\`后跟任何其他字符，都会被视为普通字符，因此它们都会被打印出来。
+- %% 一个字面的百分号。
+- %a 文件的最后访问时间，格式为 C 语言 ctime(3)函数返回的样式。
+ .....更多内容待补充
+
+##### 描述
+*暂无*
+
+#### -prune 如果文件是目录，则不进入该目录
+
+##### *无参数*
+
+##### 描述
+此选项始终返回真。
+
+##### 相关选项
+- **-depth**：如果指定了`-depth`，那么`-prune`将无效。
+- **-delete**：因为`-delete`隐含了`-depth`，所以不能有效地同时使用两者。
+
+#### -quit 立即退出
+
+##### *无参数*
+
+##### 描述
+如果没有发生错误，则返回值为零。这与`-prune `不同，因为`-prune`仅适用于被修剪目录的内容，而`-quit`则使 find 立即停止。不会有任何子进程继续运行。在程序退出之前，任何通过`-exec ... +`或`-execdir ... +`构建的命令行都会被调用。执行`-quit`后，命令行中指定的文件将不再被处理。例如，`find /tmp/foo /tmp/bar -print -quit`将仅打印 `/tmp/foo`。`-quit`的一个常见用途是在找到所需内容后停止搜索文件系统。

+始终返回真值。全局选项对命令行中较早出现的测试也会生效。为避免混淆，全局选项应在命令行上列出**起始点之后、第一个测试选项、位置选项或操作选项之前指定**。若在其他位置指定全局选项，find 会发出警告消息，说明这可能引起混淆。
+
+> 全局选项出现在起始点列表之后，因此与例如`-L` 这样的选项不属于同一类别。
+
+#### -d `-depth`的同义词
+
+##### *无参数*
+
+##### 描述
+仅用于与 FreeBSD、NetBSD、MacOS X 和 OpenBSD 兼容。
+
+#### -depth 遍历级别
+
+##### 参数
+`levels`
+
+##### 描述
+在处理目录本身之前，先处理目录中的内容。`-delete`操作也隐含了`-depth`。
+
+#### -files0-from 从文件中读取起始点，而非通过命令行获取。
+
+##### 参数
+`file`
+
+##### 描述
+
+使用此选项可以安全地给 find 命令传递任意数量的起始点。使用此选项和在命令行中传递起始点**是互斥的**，因此不允许同时进行。文件参数是强制性的。文件中的起始点必须用 ASCII NUL 字符分隔。两个连续的 NUL 字符，即带有零长度文件名的起始点是不允许的，这将导致错误诊断，并随后产生非零退出码。
+
+与标准调用不同，在标准调用中，如果没有传递路径参数，find 会默认将当前目录作为起始点。起始点的处理方式与其他情况相同，例如，find 命令会递归进入子目录，除非另有阻止。若要仅处理起始点，可以额外传递`-maxdepth 0`参数。
+
+**其他说明**：如果一个文件在输入文件中被列出多次，则其是否会被多次访问未作规定。如果在查找操作期间文件被修改，结果同样未作规定。最后，find 退出时（无论是通过`-quit`还是其他方式），命名文件中的查找位置也未作规定。此处**未作规定**意味着它**可能有效也可能无效**，**或者不做任何特定的事情**，并且该行为可能因平台或 findutils 版本而异。
+
+> :bulb:可以使用`-files0-from`**从标准输入流中读取起始点列表**，例如从管道中读取。在这种情况下，不允许使用`-ok`和`-okdir`操作，因为它们会干扰从标准输入读取以获取用户确认。
+
+> :warning:警告：如果给定文件为空，find 不会处理任何起始点，因此在解析完程序参数后会立即退出。
+
+#### -help 和 --help 打印 find 命令行用法的摘要并退出。
+
+##### *无参数*
+
+##### 描述
+*无描述*
+
+#### -ignore_readdir_race
+
+##### *无参数*
+
+##### 描述
+通常情况下，当 find 无法对文件进行状态检查（stat）时，会发出错误消息。如果您**启用此选项**，并且在 find 从目录读取文件名，到尝试进行状态检查**之间的时间内文件被删除**，则不会发出任何错误消息。这也适用于命令行中指定的文件或目录。此选项在命令行读取时生效，这意味着您不能在文件系统的某部分启用此选项，而在另一部分禁用它（如果需要这样做，您需要发出两个 find 命令，一个启用选项，一个不启用）。此外，使用`-ignore_readdir_race`选项时，如果在读取父目录后文件已消失，find 命令将忽略`-delete`操作的错误：它不会输出错误诊断信息，并且`-delete`操作的返回码将为真。
+
+####  -maxdepth 最大遍历级别
+
+##### 参数
+`levels`
+
+##### 描述
+最多向下遍历 levels 级（一个非负整数）目录层级。使用`-maxdepth 0`表示**仅对起始点本身**应用测试和操作。
+
+#### -mindepth 最小遍历级别
+
+##### 参数
+`levels`
+
+##### 描述
+在小于指定级别（非负整数）的层级上不执行任何测试或操作。使用`-mindepth 1`表示处理**除起始点外的所有文件**。
+
+#### -mount 不在其他文件系统中下降目录
+
+##### *无参数*
+
+##### 描述
+这是`-xdev`的替代名称，用于与其他一些版本的 find 兼容。
+
+#### -noignore_readdir_race
+
+##### *无参数*
+
+##### 描述
+关闭了`-ignore_readdir_race`的效果。
+
+#### -noleaf 不进行优化。
+
+##### *无参数*
+
+##### 描述
+不通过假设目录包含比其硬链接数少 2 个子目录来进行优化。在搜索不遵循 Unix 目录链接惯例的文件系统时，需要此选项，例如 CD-ROM、MS-DOS 文件系统或 AFS 卷挂载点。在正常的 Unix 文件系统上，每个目录至少有 2 个硬链接：其名称及其`.`条目。此外，其子目录（如果有）各自有一个指向该目录的`..`条目。当 find 检查一个目录时，在它已经统计了比目录链接数少 2 个子目录之后，它知道该目录中的其余条目是非目录（目录树中的“叶”文件）。如果只需要检查文件的名称，则无需对其进行状态检查；这可以显著提高搜索速度。
+
+#### -version 和 --version 打印 find 的版本号并退出。
+
+##### *无参数*
+
+##### 描述
+*无描述*
+
+#### -xdev 不进入其他文件系统的目录。
+
+##### *无参数*
+
+##### 描述
+*无描述*
+
+### 位置选项
+始终返回真值。它们仅影响命令行中后续的测试。
+
+#### -daystart 从今天开始
+
+> 用于 `-amin`、`-atime`、`-cmin`、`-ctime`、`-mmin` 和 `-mtime`
+
+##### *无参数*
+
+##### 描述
+从今天开始而非从 24 小时前开始。此选项仅影响命令行中后续出现的测试。
+
+#### ~~-follow~~ 解引用符号链接。
+
+##### *无参数*
+
+##### 描述
+**已弃用，请改用`-L`选项**。隐含`-noleaf`。`-follow`选项仅影响命令行中出现在其后的那些测试。除非已指定`-H`或`-L`选项，否则`-follow`选项的位置会改变`-newer`谓词的行为；作为`-newer`参数列出的任何文件，如果它们是符号链接，则会被解引用。同样的情况适用于`-newerXY`、`-anewer`和`-cnewer`。类似地，`-type `谓词将始终匹配符号链接所指向的文件类型，而非链接本身。使用`-follow`会导致  `-lname`和`-ilname`谓词始终返回 false。
+
+#### -regextype 更改正则表达式语法
+
+##### 参数
+`type`
+
+##### 描述
+更改`-regex`和`-iregex`测试在命令行后续部分所理解的正则表达式语法。要查看已知的正则表达式类型，请使用`-regextype help`。Texinfo 文档解释了各种正则表达式类型的含义及其差异。如果您不使用此选项，find 的行为如同已指定正则表达式类型为`emacs`。
+
+#### -warn 和 -nowarn 开启或关闭警告消息。
+
+##### *无参数*
+
+##### 描述
+这些警告仅适用于命令行使用，不适用于 find 在搜索目录时可能遇到的情况。默认行为是：如果标准输入是`tty`，则对应`-warn`；否则对应`-nowarn`。如果产生与命令行使用相关的警告消息，find 的退出状态不受影响。如果设置了 POSIXLY_CORRECT 环境变量，并且也使用了`-warn`，则未指定哪些（如果有）警告会被激活。
+
+### 运算符选项
+运算符按优先级递减顺序列出：
+- `(expr)` 强制优先级。由于括号对 shell 有特殊含义，通常需要对它们进行引用。许多示例为此使用了反斜杠：`\(...\)` 而非 `(...)`。
+- `! expr` 若表达式为假则结果为真（取反）。此字符通常也需要防止被 shell 解释。
+
+> :bulb:提示：当`-a`隐式指定（例如两个测试之间没有显式运算符）或显式指定时，其优先级高于`-o`。例如，`find . -name foo -o -name bar -print`永远不会打印`foo`。
+
+#### -not
+
+##### 参数
+`expr`
+
+##### 描述
+等同于`! expr`，但不符合 POSIX 标准。
+
+#### -a 
+
+##### 参数
+`expr1` -a `expr2`
+
+##### 描述
+两个连续的表达式被视为隐含地用`-a`连接；如果`expr1`为假，则不评估`expr2`。等同于`expr1 expr2`。
+
+#### -and
+
+##### 参数
+`expr1` -and `expr2`
+
+##### 描述
+与`-a`相同。但不符合 POSIX 标准。
+
+#### -o
+
+##### 参数
+`expr1` -o `expr2`
+
+##### 描述
+`expr1`和`expr2`始终都会被评估。`expr1`的值会被丢弃；列表的值即为`expr2`的值。逗号运算符（`,`）在搜索多种不同类型的事物时非常有用，但只会遍历文件系统层次结构一次。`-fprintf`动作可用于将各种匹配项列出到多个不同的输出文件中。若`expr1`为真，则不评估`expr2`。
+#### -or
+
+##### 参数
+`expr1` -or `expr2`
 
-起始目录：查找文件的起始目录。
+##### 描述
+与`-o`相同。但不符合 POSIX 标准。
 
-### 实例
+## 例子
 
+当前目录搜索所有文件，且文件内容包含 “140.206.111.111” 
 ```shell
-# 当前目录搜索所有文件，文件内容 包含 “140.206.111.111” 的内容
 find . -type f -name "*" | xargs grep "140.206.111.111"
 ```

+# iostat
 
-监视系统输入输出设备和CPU的使用情况
+iostat命令被用于监视系统输入输出设备和CPU的使用情况。它的特点是汇报磁盘活动统计情况，同时也会汇报出CPU使用情况。同vmstat一样，iostat也有一个弱点，就是它不能对某个进程进行深入分析，仅对系统的整体情况进行分析。
+iowait 指在一个采样周期内有百分之几的时间是属于以下情况：CPU处于空闲状态并且至少有一个未完成的磁盘IO请求。
 
-## 补充说明
+## 安装 iostat
 
-**iostat命令** 被用于监视系统输入输出设备和CPU的使用情况。它的特点是汇报磁盘活动统计情况，同时也会汇报出CPU使用情况。同vmstat一样，iostat也有一个弱点，就是它不能对某个进程进行深入分析，仅对系统的整体情况进行分析。
+iostat包含在**sysstat**包内。如果你没有，你首先需要安装它。
+在 RedHat / CentOS / Fedora
 
-###  语法
+```bash
+yum install sysstat 
+```
+
+在 Debian / Ubuntu / Linux Mint
+
+```bash
+sudo apt-get install sysstat
+```
 
-```shell
+## 语法
+
+```bash
 iostat(选项)(参数)
 ```
 
-###  选项
-
-```shell
--c：仅显示CPU使用情况；
--d：仅显示设备利用率；
--k：显示状态以千字节每秒为单位，而不使用块每秒；
--m：显示状态以兆字节每秒为单位；
--p：仅显示块设备和所有被使用的其他分区的状态；
--t：显示每个报告产生时的时间；
--V：显示版号并退出；
--x：显示扩展状态。
+### 选项
+
+```bash
+# iostat --help
+Usage: iostat [ options ] [ <interval> [ <count> ] ]
+Options are:
+[ -c ] [ -d ] [ -h ] [ -k | -m ] [ -N ] [ -s ] [ -t ] [ -V ] [ -x ] [ -y ] [ -z ]
+[ -j { ID | LABEL | PATH | UUID | ... } ] [ --human ] [ -o JSON ]
+[ [ -H ] -g <group_name> ] [ -p [ <device> [,...] | ALL ] ]
+```
+
+参数说明：
+```
+-c         输出CPU统计信息。不能与-d参数同时使用。
+-d         输出设备和分区的I/O统计信息。不能与-c参数同时使用。(默认的参数是-d)。
+-h         让人类更容易阅读设备使用情况报告。--human使用此选项隐式启用。
+-k         用“kbytes/秒”代替“块/秒”显示统计信息。
+-m         用“mbytes/秒”代替“块/秒”显示统计信息。
+-t         打印显示的每份报告的时间。
+-V         显示版本号并退出。
+-x         显示扩展统计信息。不能与参数-p同时使用。
+-y         如果在给定时间间隔内显示多条记录，则省略自系统启动以来的第一份统计报告。
+-z         告诉 iostat 忽略在样本期间没有活动的设备的输出。
+-j         显示持久的设备名称。选项ID、LABEL等指定持久名称的类型。
+--human    以人类可读格式打印大小(例如1.0k, 1.2M等)。使用此选项显示的单位取代与度量相关的任何其他默认单位(例如千字节，扇区…)。
+-o         以JSON (Javascript Object Notation)格式显示统计数据。JSON输出字段顺序未定义，未来可能会添加新字段。
+-H         该选项必须与-g一起使用，表示只显示组的全局统计信息，而不显示组中单个设备的统计信息。
+-p         选项显示系统使用的块设备及其所有分区的统计信息。如果在命令行中输入一个设备名，那么将显示该设备及其所有分区的统计信息。最后，ALL关键字表示必须显示系统定义的所有块设备和分区的统计信息，包括那些从未使用过的设备和分区。如果在此选项之前定义了选项-j，则可以使用所选的持久名称类型指定在命令行上输入的设备。

+从这里你可以看到，iostat 提供了非常丰富的性能指标。第一列的 Device 表示磁盘设备的名字，其他各列指标，虽然数量较多，但是每个指标的含义都很重要。
+
+| 性能指标 | 含义 |
+| --- | --- |
+| r/s | 设备每秒完成的读取请求数（合并后）。 |
+| w/s | 设备每秒完成的写入请求数（合并后）。 |
+| rkB/s | 每秒从设备读取的扇区数（千字节、兆字节）。 |
+| wkB/s | 每秒写入设备的扇区数（千字节、兆字节）。 |
+| rrqm/s | 每秒合并到设备的排队 I/O 请求数。 |
+| wrqm/s | 每秒合并到设备的写入请求数。 |
+| %rrqm | 在发送到设备之前合并在一起的读取请求的百分比。 |
+| %wrqm | 发送到设备前合并在一起的写入请求的百分比。 |
+| r_await | 向设备发出的读取请求获得服务的平均时间（毫秒）。这包括请求在队列中花费的时间和为请求提供服务的时间。 |
+| w_await | 向待服务设备发出写入请求的平均时间（毫秒）。这包括请求在队列中花费的时间和为请求提供服务的时间。 |
+| aqu-sz | 向设备发出的请求的平均队列长度。注意：在以前的版本中，该字段被称为 avgqu-sz。 |
+| rareq-sz | 向设备发出的读取请求的平均大小（千字节）。 |
+| wareq-sz | 向设备发出的写入请求的平均大小（千字节）。 |
+| svctm | 向设备发出的 I/O 请求的平均服务时间（毫秒）。警告！不要再相信这个字段了。 未来的 sysstat 版本将删除此字段。 |
+| %util | 向设备发出 I/O 请求所用时间的百分比（设备带宽利用率）。 对于串行服务请求的设备，当该值接近 100%，设备就会饱和。 但对于以并行方式提供请求的设备，如 RAID 阵列和现代固态硬盘，该数值并不能反映其性能极限。 |
+
+当 %iowait 升高，需要重点关注以下指标：
+
+- avgrq-sz:  向设备发出请求的平均大小（单位：扇区）
+- avgqu-sz:  向设备发出请求的队列平均长度。也是个做 IO 调优时需要注意的地方，这个就是直接每次操作的数据的大小，如果次数多，但数据拿的小的话，其实 IO 也会很小.如果数据拿的大，IO 的数据会高
+- r_await:   向服务设备发出读取请求的平均时间（单位：毫秒）。包括请求入队的时间以及设备处理请求的时间
+- w_await:   向服务设备发出写请求的平均时间（单位：毫秒）。包括请求入队的时间以及设备处理请求的时间
+- %util：一秒中有百分之多少的时间用于 I/O 操作，或者说一秒中有多少时间 I/O 队列是非空的。如果 %util 接近 100%，说明产生的I/O请求太多，I/O系统已经满负荷，该磁盘可能存在瓶颈
+- %svctm：平均每次设备 I/O 操作的服务时间 (毫秒)。一般要小于 await (因为同时等待的请求的等待时间被重复计算了)，svctm 的大小一般和磁盘性能有关，CPU/内存的负荷也会对其有影响，请求过多也会间接导致 svctm 的增加。await 的大小一般取决于服务时间(svctm) 以及 I/O 队列的长度和 I/O 请求的发出模式。如果 svctm 比较接近 await，说明 I/O 几乎没有等待时间；如果 await 远大于 svctm，说明 I/O 队列太长，应用得到的响应时间变慢，如果响应时间超过了用户可以容许的范围，这时可以考虑更换更快的磁盘，调整内核 elevator 算法，优化应用，或者升级 CPU

-# iostat
+iostat
+===
 
 iostat命令被用于监视系统输入输出设备和CPU的使用情况。它的特点是汇报磁盘活动统计情况，同时也会汇报出CPU使用情况。同vmstat一样，iostat也有一个弱点，就是它不能对某个进程进行深入分析，仅对系统的整体情况进行分析。
 iowait 指在一个采样周期内有百分之几的时间是属于以下情况：CPU处于空闲状态并且至少有一个未完成的磁盘IO请求。

+# 快速入门指南
+
+本指南旨在帮助您在 Kubernetes 中部署基于 `wcjiang/linux-command` 镜像的 `linux-command` 应用。该应用提供了一套 `Deployment`，并通过 `Service` 对外暴露服务端口。
+
+## 前提条件
+
+- 已安装并配置好的 Kubernetes 集群
+- 安装并配置好的 `kubectl`，并连接至你的 Kubernetes 集群
+
+## 安装步骤
+
+我们将使用此存储库中的`kubectl`应用 YAML 文件，该文件将安装 `linux-command` 应用。
+
+```bash
+$ kubectl apply -f https://raw.githubusercontent.com/jaywcjlove/linux-command/master/deploy/yamls/linux-command.yaml
+```
+
+检查 `Deployment` 状态：
+
+```bash
+$ kubectl get deployments -n linux-command
+NAME            READY   UP-TO-DATE   AVAILABLE   AGE
+linux-command   1/1     1            1           17m
+```
+
+你可以查看 `Pod` 的状态以确保其正常运行：
+
+```bash
+$ kubectl get pods -n linux-command
+NAME                            READY   STATUS    RESTARTS   AGE
+linux-command-fff454654-427zp   1/1     Running   0          12m
+```
+
+验证 `Service` 是否成功创建并获取暴露的端口：
+
+```
+$ kubectl get services -n linux-command
+NAME                    TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE
+linux-command-service   NodePort   10.96.2.225   <none>        9665:30204/TCP   18m
+```
+
+## 访问应用
+
+通过获取 `NodePort` 的端口来访问应用。以下是获取 `NodePort` 服务信息的命令：
+
+```
+$ kubectl get svc linux-command-service -n linux-command
+```
+
+根据输出，使用 `EXTERNAL-IP:PORT` 访问服务。例如：
+
+```
+http://<Node-IP>:<NodePort>
+```
+
+## 卸载应用
+
+如果需要删除已部署的资源，可以按以下顺序操作：
+
+```
+kubectl delete -f linux-command.yaml
+```
+
+这将会清理所有创建的 Kubernetes 资源。

+description: A Helm chart for Kubernetes
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 0.1.0
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.

 无论是否将 nohup 命令的输出重定向到终端，输出都将附加到当前目录的 nohup.out 文件中。如果当前目录的 nohup.out 文件不可写，输出重定向到`$HOME/nohup.out`文件中。如果没有文件能创建或打开以用于追加，那么 command 参数指定的命令不可调用。如果标准错误是一个终端，那么把指定的命令写给标准错误的所有输出作为标准输出重定向到相同的文件描述符。

-**at命令** 用于在指定时间执行命令。at允许使用一套相当复杂的指定时间的方法。它能够接受在当天的hh:mm（小时:分钟）式的时间指定。假如该时间已过去，那么就放在第二天执行。当然也能够使用midnight（深夜），noon（中午），teatime（饮茶时间，一般是下午4点）等比较模糊的 词语来指定时间。用户还能够采用12小时计时制，即在时间后面加上AM（上午）或PM（下午）来说明是上午还是下午。 也能够指定命令执行的具体日期，指定格式为month day（月 日）或mm/dd/yy（月/日/年）或dd.mm.yy（日.月.年）。指定的日期必须跟在指定时间的后面。

-上面介绍的都是绝对计时法，其实还能够使用相对计时法，这对于安排不久就要执行的命令是很有好处的。指定格式为：`now + count time-units`，now就是当前时间，time-units是时间单位，这里能够是minutes（分钟）、hours（小时）、days（天）、weeks（星期）。count是时间的数量，究竟是几天，还是几小时，等等。 更有一种计时方法就是直接使用today（今天）、tomorrow（明天）来指定完成命令的时间。

+getfacl
+===
+
+获取文件访问控制列表(access control lists)
+
+## 补充说明
+
+对于每个文件，`getfacl`都会显示文件名、所有者、组和访问控制列表 (ACL)。如果目录有默认ACL，`getfacl` 也会显示默认ACL。非目录不能有默认ACL。
+如果在不支持 ACL 的文件系统上使用`getfacl`，`getfacl`会显示由传统文件模式权限位定义的访问权限。请参考`setfacl`。
+
+###  选项
+
+```shell
+-a, --access              # 显示文件访问控制列表。
+-d, --default             # 显示默认访问控制列表。
+-c, --omit-header         # 不显示注释头（每个文件输出的前三行）。
+-e, --all-effective       # 打印所有有效权限注释，即使与 ACL 条目定义的权限相同。
+-E, --no-effective        # 不打印有效权限注释。
+-s, --skip-base           # 跳过只有基本 ACL 条目（所有者、组、其他）的文件。
+-R, --recursive           # 递归列出所有文件和目录的 ACL。
+-L, --logical             # 逻辑路径，跟踪目录的符号链接。默认行为是跟踪符号链接参数，跳过子目录中遇到的符号链接。仅与 -R 结合使用时有效。
+-P, --physical            # 物理路径，不跟踪指向目录的符号链接。这也会跳过符号链接参数。 仅与 -R 结合使用时有效。
+-t, --tabular             # 使用另一种表格输出格式。同时显示 ACL 和默认 ACL。因 ACL 屏蔽条目而无效的权限会以大写。ACL_USER_OBJ 和 ACL_GROUP_OBJ 条目的条目标签名称也以大写字母显示，这有助于识别这些条目。
+-p, --absolute-names      # 不删除前导斜线字符 (`/')。默认行为是去掉前导斜线字符。
+-n, --numeric             # 列出数字用户和组 ID。
+-v, --version             # 打印 getfacl 的版本并退出。
+-h, --help                # 打印命令行选项的帮助说明。
+--                        # 命令行选项结束。所有剩余参数都被解释为文件名，即使它们以破折号字符开头。
+-                         # 如果文件名参数是单破折号字符，getfacl 将从标准输入读取文件列表。
+```
+
+###  实例
+
+getfacl 命令默认显示文件访问控制列表。打开终端，并输入以下命令：
+
+```shell
+getfacl tmp 
+
+# file: tmp
+# owner: zdx
+# group: zdx
+# flags: -s-
+user::rwx
+group::rwx
+other::r-x
+default:user::rwx
+default:group::rwx
+default:other::r-x
+```

+nstat
+===
+
+nstat 是一个简单的监视内核的 SNMP 计数器和网络接口状态的实用工具。
+
+## 补充说明
+
+大多数命令行用户都熟悉 netstat ，这是 net-tools 软件包中的命令。目前新版本中 net-tools 软件包几乎完全被弃用，取而代之的是 ip 命令套件，而 nstat 属于新软件包。
+
+###  语法
+
+```s
+nstat [OPTION] [ PATTERN [ PATTERN ] ]
+```
+
+###  选项
+
+```shell
+-h：显示帮助信息；
+-V：显示指令版本信息；
+-z：转储零计数器。默认情况下不显示它们；
+-r：清零历史统计；
+-n：不显示任何内容，仅更新历史；
+-a：显示计数器的绝对值；
+-d：以守护进程模式运行并收集统计数据
+-s：不更新历史；
+-j：JSON格式输出。
+```
+
+### 实例
+
+直接输入以查询网络接口状态，以下展示了 IPv4，IPv6，TCP，UDP，ICMP 的统计数据：

+
+ubuntu防火墙管理工具
+
+## 概要
+
+```shell
+sudo ufw [选项] [规则/命令]
+```
+
+## 用途
+
+- 管理Ubuntu系统防火墙规则，简化`iptables`操作。
+- 启用或禁用防火墙，查看当前防火墙状态。
+- 快速配置允许/拒绝端口、服务或特定IP的访问。
+
+## 参数
+
+### 常用操作命令
+
+- `enable`: 启用防火墙并设置开机自启。
+- `disable`: 关闭防火墙。
+- `reload`: 重新加载防火墙规则（不中断现有连接）。
+- `reset`: 重置所有规则到初始状态。
+- `allow <rule>`: 允许指定规则（如端口、服务）。
+- `deny <rule>`: 拒绝指定规则。
+- `status`: 显示防火墙状态和规则列表。
+
+### 规则格式
+
+- `<port>`: 端口号（如 `22`、`80/tcp`）。
+- `<protocol>`: 协议类型（`tcp` 或 `udp`）。
+- `comment <text>`: 为规则添加注释（需配合 `allow`/`deny` 使用）。
+
+### 选项
+
+- `--dry-run`: 仅显示规则变更，不实际应用。
+
+------
+
+## 返回值
+
+- 成功执行返回 `0`。
+- 错误或无效参数返回非零值。
+
+------
+
+## 示例
+
+### 基础操作
+
+```
+# 启用防火墙
+sudo ufw enable
+
+# 关闭防火墙
+sudo ufw disable
+
+# 查看防火墙状态
+sudo ufw status
+```
+
+### 规则配置
+
+```
+# 允许SSH默认端口（22/tcp）
+sudo ufw allow ssh
+
+# 允许TCP协议的8080端口并添加注释
+sudo ufw allow 8080/tcp comment "Web Server"
+
+# 拒绝来自192.168.1.5的访问
+sudo ufw deny from 192.168.1.5
+
+# 拒绝UDP协议的53端口
+sudo ufw deny 53/udp
+```
+
+### 高级操作
+
+```
+# 显示带编号的规则列表（便于删除）
+sudo ufw status numbered
+
+# 删除第3条规则
+sudo ufw delete 3
+
+# 重置所有规则
+sudo ufw reset
+```
+
+------
+
+## 注意
+
+1. **权限要求**：需使用 `sudo` 执行命令。
+2. **默认策略**：首次启用时默认阻止所有入站流量，允许所有出站流量。
+3. **规则优先级**：
+   规则按顺序匹配，先拒绝后允许可能导致冲突
+4. **日志记录**：
+   可通过 `sudo ufw logging on` 启用日志，日志路径为 `/var/log/ufw.log`
+5. **服务名称支持**：
+   支持 `/etc/services` 中定义的服务名（如 `http`、`ssh`）

+getcap
+===
+
+显示文件的能力（capabilities）
+
+## 补充说明
+
+**getcap命令** 用于查看文件的能力（capabilities）。在 Linux 中，文件的能力是一种权限控制机制，可以赋予普通文件特定的特权操作，而无需完全的 root 权限。
+
+### 语法
+
+```shell
+getcap [选项] [文件名...]
+```
+
+### 选项
+
+```shell
+-v      # 显示详细信息，通常与其他选项一起使用。
+-p      # 显示进程的能力。
+```
+
+### 参数
+
+文件名：指定要查看能力的文件路径。
+
+### 实例
+
+查看一个可执行文件的能力：
+
+```shell
+$ getcap /usr/bin/ping
+/usr/bin/ping = cap_net_raw+ep
+```
+
+查看当前目录下所有文件的能力：
+
+```shell
+$ getcap *
+/usr/bin/ping = cap_net_raw+ep
+```
+
+如果文件没有设置任何能力，getcap 不会返回任何输出。
+
+查看进程的能力（以 PID 为例）：
+
+```shell
+$ getcap -p 1234
+```
