Question

I have one GIT repository in which a number of users (Say A, B, …..X) committed the file.
I want to delete or revert all the files which are committed by the User ‘X’.

Is it possible or do I have to do that manually?

Answer 1

Try this:

git log --author=X --format="%H" | xargs git revert

The first part of the pipeline produces all SHA1s of commits where the username matches the regular expression (!) X; the second part calls a git revert on those commits. If one of the commits fails to revert cleanly, though, you might want to just walk through the output of

git log --author=X --oneline

and revert by hand.
