Some of you might be familiar with my [Command Line Text Processing](https://github.com/learnbyexample/Command-line-text-processing) repo. This book is based on the `grep` chapter - edited to add more descriptions, better examples, exercises, etc. Also, I took the plunge and checked out `ripgrep` while working on this book. I'd assumed it would be similar to `gnu grep` and I just need simple changes to present it in the book. Well, it turned out lot more work and I had to settle for not covering all the options and customizations. In hindsight, would've been better if I did a separate book. Speed wise, `ripgrep` is very impressive and has plenty of additional nice features. For example: the multiline `-U` and replace `-r` options of `ripgrep` are quite handy - you can use this instead of `sed` for some cases with added advantage of speed, `-F` option and better regex features.

I plan to add more content to the book in future and hopefully create an interactive course. Currently the book is licensed under [cc-by-nc-sa](https://creativecommons.org/licenses/by-nc-sa/4.0/) with code snippets under [MIT](https://github.com/learnbyexample/py_regular_expressions/blob/master/LICENSE) and I'll probably add the source files to the repo sometime in the future. I'm generating the PDF using [pandoc+xelatex](https://learnbyexample.github.io/tutorial/ebook-generation/customizing-pandoc). I plan to create an epub version too and possibly put the book on Amazon Kindle.
