Check if current directory is a Git repository

I am writing a series of scripts for Git management in zsh.

How do I check if the current directory is a Git repository? (When I'm not in a Git repo, I don't want to execute a bunch of commands and get a bunch of fatal: Not a git repository responses).

Solution

  • Copied from the bash completion file, the following is a naive way to do it

if [ -d .git ]; then
  echo .git;
else
  git rev-parse --git-dir 2> /dev/null;
fi;

    You could either wrap that in a function or use it in a script.

    Condensed into a one line condition suitable for bash and zsh

    [ -d .git ] && echo .git || git rev-parse --git-dir > /dev/null 2>&1
