Here is my command prompt from my .bash_profile. The command prompt detects whether it's in a git project or not and if it is, it indicates the current branch and whether there are un-staged changes pending.
# RETURN ASTERISK WHEN CHANGES ARE PRESENT BUT UNSTAGED
function parse_git_dirty {
[[ $(git status 2> /dev/null | tail -n1) != "nothing to commit (working directory clean)" ]] && echo "*"
}
# GET THE CURRENT GIT BRANCH
function parse_git_branch() {
if [ -d "./.git" ]; then
git branch 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/[\1$(parse_git_dirty)]/"
fi
}

NOTE: since checking ./.git is only checking the root directory, the git branch will not show if you are in a sub-directory of a git repo. I sort of want mine to work this way because it's better than calling git branch at every prompt.
