Determine if directory is under git control

Question

How can I tell if a given directory is part of a git respository?

(The following is in python, but bash or something would be fine.)

os.path.isdir(\'.svn         


        

Answer 1

Add this to your .bash_profile, and your prompt will always show the active git branch and whether you have uncommitted changes.

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=' \[\033[0;33m\]\w\[\033[00m\]\[\033[01;00m\]$(parse_git_branch): ' #PS1='\w> '

You'll see this:
