Bash Git Branch

gistfile1.sh

function parse_git_dirty {
  [[ $(git status 2> /dev/null | tail -n1) != "nothing to commit (working directory clean)" ]] && echo "*"
}

function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/[\1$(parse_git_dirty)]/"
}

export PS1="\n\[$BPurple\][\w]\n\[$BCyan\]\u@\h \[$BGreen\]\$(parse_git_branch)\n$\[$Color_Off\] "


# The BGreen color it is using is BGreen='\e[1;32m', however, I set my iTerm to change the hue of the colors -- so it might look different in your terminal

cleaned up those two functions, case you want to use them: https://gist.github.com/3019590

Definitely a lot cleaner, but also markedly slower (at least on my machine).

humm.. i didn't notice any performance issue.. i'd still replace parse_git_dirty if i were you.. searching for a string to check the status of a repo is kinda brittle.. that's what the --porcelain stuff was created for

That seems to work better, overall.
