Show the Git branch in your terminal prompt

This is a cool hack to have your current git branch show up in your terminal prompt. It ends up looking like this:


If you're not in a git repository the [my-dev-branch] bit won't be there and it'll just be your regular prompt.

All you have to do is add the following to the bottom of your ~/.bashrc file:

function git-branch-prompt {
    branch=$(git branch 2>/dev/null | grep '^*' | colrm 1 2)
    if [ $branch ]; then printf " [%s]" $branch; fi
PS1=`echo ${OPS1:0:-3}'$(git-branch-prompt)\$ '`
