Neat PS1 setting for git users

If you add this to .bashrc, then it produces a handy visual reminder for which git branch is being worked on. Very useful to not mess with master when you are supposed to be working on a different branch!

parse_git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;36m\]\u@\h: \w\[\033[00;31m\]$(parse_git_branch)\[\033[00m\] \$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

I have set mine to use a different colour for the git branch:

    damo@debian: ~/github/scripts(testing) $ git status
    On branch testing
    Your branch is up to date with 'origin/testing'.
    damo@debian: ~/github/scripts(testing) $ git checkout master
    Switched to branch 'master'
    Your branch is up to date with 'origin/master'.
    damo@debian: ~/github/scripts(master) $

Re: Neat PS1 setting for git users

I've added red text in your function, as a warning to myself when in the master branch  :8

prompt_git ()       
{                                                               
    git symbolic-ref HEAD &> /dev/null || return 1;
    local HEAD="$(git symbolic-ref HEAD 2>/dev/null)";                                                                                
    local BRANCH="${HEAD#refs/heads/}"; 
    if [[ $BRANCH = "master" ]];then                                                                                              
        printf '%b(git:%s)' "\033[0;31m" "${BRANCH:-unknown}"       
    else
        printf '%b(git:%s)' "\033[0;32m" "${BRANCH:-unknown}"  
    fi
}
