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).
You can use:
git rev-parse --is-inside-work-tree
Which will print 'true' to STDOUT if you are in a git repos working tree.
Note that it still returns output to STDERR if you are outside of a git repo (and does not print 'false').
