“git diff” does nothing

Question

If you are using it outside of a real repository or work-copy, its behaviour is identical to the GNU diff. So you need to inform the 2 directories or files to be compared. Example:

git diff old_dir new_dir.

If there is any difference between them, the output will show you, as expected.
