Using Git Diff Without a Repo

Featured image for sharing metadata for article

I really like using git diff, as it's got some good defaults, and has some good options on top of it.

But when you're not in a Git repo, you can't use it, right? Not quite.

Fortunately, there's the --no-index flag which allows you to diff between files that aren't related to a Git repo:

# does not work, returns status code 0
git diff ../other-repo/
# works, returns status code 1 and the diff
git diff --no-index ../other-repo/
