### Using Git Diff Without a Repo ([src](https://www.jvt.me/posts/2020/10/29/git-diff-no-repo/))
The --no-index flag allows you to diff between files that aren't related to a Git repo:
#### does not work, returns status code 0
`git diff README.md ../other-repo/README.md`
#### works, returns status code 1 and the diff
`git diff --no-index README.md ../other-repo/README.md`
