ssh-url-with-ssh-key is a wrapper for ssh that extracts a base64 encoded SSH key
from the SSH user~key@host URL and launches SSH with that key.
Set the GIT_SSH environment variable to this script (ssh-url-with-ssh-key)
to activate it for your git usage.
Usage:
ssh-url-with-ssh-key [--help | --create | user~key@host] [command]
--create Create a new private and public SSH key. This will print
out the private key as you should append it to the SSH
user and the public key to add to a remote system.
Example usage:
# clone GitHub repo with Deploy Keys
$ GIT_SSH=ssh-url-with-ssh-key git clone git~LS0tLS1CRUdJTiBP....SDFWENF324DS=@github.com:user/repo.git
# connect to remote SSH server
$ ssh-url-with-ssh-key user~LS0tLS1CRUdJTiBP....SDFWENF324DS=@host
# create new SSH key pair
$ ./ssh-url-with-ssh-key --create schlomo test
Append this base64-encoded private key to the username:
