How can I reset or revert a file to a specific revision?

Question

I have made some changes to a file which has been committed a few times as part of a group of files, but now want to reset/revert the changes on it back to a previous versio

Answer 1

git revert 

Will revert a given commit. It sounds like you think git revert only affects the most recent commit.

That doesn't solve your problem, if you want to revert a change in a specific file and that commit changed more than that file.
