Show current git branch in PS1 when branch is not master

Short post, long command…

I’ve decided to start showing the current git branch in my PS1. However, since I don’t want to know when I’m on master, I had to write a new PS1 that I haven’t yet seen anywhere. Add the following to your .bashrc:

PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
if [ -e /usr/share/git-core/contrib/completion/git-prompt.sh ]; then
    . /usr/share/git-core/contrib/completion/git-prompt.sh
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$([ "$(__git_ps1 %s)" != "" -a "$(__git_ps1 %s)" != "master" ] && (echo -e " (\[33[32m\]"$(__git_ps1 "%s")"\[33[0m\])") || echo "")\$ '
fi

This keeps my PS1 short for when I’m hacking on personal repositories that only have a single branch. Keep in mind that you might have to change the path to git-prompt.sh depending on what OS you’re using.

Example:

james@computer:~/code/puppet$ cd puppet-gluster
james@computer:~/code/puppet/puppet-gluster$ git checkout -b cool-new-feature
Switched to a new branch 'cool-new-feature'
james@computer:~/code/puppet/puppet-gluster (cool-new-feature)$ # tada !

The branch name is coloured to match the default colours that git uses to colour branches.

Happy hacking,

James
