After getting a bit confused when having too many branches, and for people who don't mind extra forks and like too much info in their prompt, I've recently started using this:

export PS1='!\! [\j] \u@\h:\w$(output-git-head-or-blank)\$ '

where output-git-head-or-blank is:

#!/bin/bash

PS_GIT=$(git-symbolic-ref HEAD 2>/dev/null) && echo "[$(basename $PS_GIT)]" && exit

# else output nothing

When in a non-git directory, you get a non-git prompt (of course, modify this to whatever you want)

!502 [0] benc@piva:~$

and when in a git directory you get (a truncated form of) whatever today's head points at:

!502 [0] benc@piva:~$ cd src/globe !503 [0] benc@piva:~/src/globe[master]$
