Putting git info onto shell prompt

git-prompt.sh

Allows you to see repository status in your command prompt.

The script can be found here.

This can be 'installed' as follows:

• Copy the file somewhere
• Then add source path/to/git-prompt.sh at the end of ~/.bashrc

To add git repo information to your bash prompt:

• Get current prompt layout, $ echo $PS1
• Copy the output and add $(__git_ps1 " (%s)") somewhere in it
• Add the line export PS1=YOUR_EDITED_LAYOUT at the end of ~/.bashrc
• Restart bash
  • If you get the error bash: __git_ps1: command not found, then make sure that the git-prompt.sh is run properly
