Display git branch in bash prompt

.bashrc

# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer!

export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ "

# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty!

# ~/code/web:beta_directory$ git checkout master
# Switched to branch "master"
# ~/code/web:master$ git checkout beta_directory
# Switched to branch "beta_directory"
# ~/code/web:beta_directory$ 

*git branch* should only be called when a .git folder exists Filip Oščádal 🍀📱

You can color it whatever you want when using it in your PS1 variable. It will only display if you're on a git repo. Took inspiration from some of the ideas posted here. Feel free to improve upon it as you see fit. I know it is far from perfect, so any criticism and ideas are welcome, as I've just started getting into shell scripting. I tried to keep it POSIX for compatibility (I just checked with shellcheck -s sh so I'm not really sure if I did it right). parse_git_branch() { GIT_BRANCH="$(git branch --show-current 2> /dev/null)" [ -d .git ] && printf "(%s)" "$GIT_BRANCH" } I plan on getting it to change color automatically when there are unstaged changes in the repo, as some other users have shown here, but my current level of experience has made it difficult for me, so if anyone can come up with an efficient solution feel free to expand upon this. I know I could just use the same ideas posted here, just wanted to see if I could come up with something on my own first. — Reply to this email directly, view it on GitHub <https://gist.github.com/168835#gistcomment-4128251>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/AAASMXUFFHU6FA367KFJ5CDVEN67FANCNFSM4HKY7JKQ> .

Working fine

function parse_git_dirty {
[[ $(git status 2> /dev/null | tail -n1) != "nothing to commit, working tree clean" ]] && echo ""
}
function parse_git_branch {
git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/ (.*)/(\1$(parse_git_dirty))/"
}
export PS1='[\e[\033[01;34m]\u@\h [\e[38;5;211m]\W[\e[\033[38;5;48m] $(parse_git_branch)[\e[\033[00m]$ '

he11 yeah! This color scheme is hands down the best on the internet. No contest. If this was mortal kombat this color code whispers "finish them"

I edited a bit @vankasteelj's stuff and made something like zsh, to react to git's changes If there are some changes then the color changes to orange or whatever, like in zsh (or fish also, I don't know) so, to do that, you need to create a function

function changes_in_branch() { 
    if [ -d .git ]; then
	if expr length + "$(git status -s)" 2>&1 > /dev/null; then     
	    echo -ne "\033[0;33m$(__git_ps1)\033[0m"; 
	else
	    echo -ne "\033[0;32m$(__git_ps1)\033[0m"; fi; 
    fi
}

and then simply just add that function to the PS1 stuff. Just like this:

PS1='\[\033[0;32m\]\[\033[0m\033[0;32m\]\u\[\033[0;36m\] @ \[\033[0;36m\]\h \w\[\033[0m\]$(changes_in_branch)\n\[\033[0;32m\]└─\[\033[0m\033[0;32m\] \$\[\033[0m\033[0;32m\] ▶\[\033[0m\] '

Works perfect in a Laptop with WSL and Ubuntu. I recently moved to a Macbook with M1, tried to use the same logic unsucessfully. After some tweaks I edited the changes_in_branch() function to make it work in my Mac. This is the result:

function changes_in_branch() {
    if [ -d .git ]; then
        ChangesStr="$(git status -s)"
        if [[ -n $ChangesStr ]]; then
            echo -ne "\033[0;33m$(__git_ps1)\033[0m";
        else
            echo -ne "\033[0;32m$(__git_ps1)\033[0m"; fi;
    fi
}

I had also to install bash-git-prompt in order to make work __git_ps1
