Want to exclude file from “git diff”

Question

I am trying to exclude a file (db/irrelevant.php) from a Git diff. I have tried putting a file in the db subdirectory called .gitattributes

Answer 1

This method is shorter than the accepted answers.

git diff 987200fbfb 878cee40ba --stat -- ':!*.cs'
