Same here. Here's the script for a git-aware bash prompt if anyone else is interested.

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)/"

}

PS1='[\w$(parse_git_branch)] '
