I always have the problem remembering in which branch I am, and typing git branch all the time sucks, so just add this to your profile:
if [-e /etc/bash_completion.d/git] ; then
source /etc/bash_completion.d/git
export PS1='$(ppwd l)u@h:w$(__git_ps1 "(%s)")> '
fi
And your prompt will look like this if you are in a git checkout:
dmacvicar@piscola:/space/git/suse/zypp(master)>
