How to tell if a file is git tracked (by shell exit code)?

Question

Is there a way to tell if a file is being tracked by running some git command and checking its exit code?

In other words: is git tracking a file?

Answer 1

Try running git status on the file. It will print an error if it's not tracked by git

PS$> git status foo.txt
error: pathspec 'foo.txt' did not match any file(s) known to git.
