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

If you know how many commits you need to go back, you can use:

git checkout master~5 image.png

This assumes that you're on the master branch, and the version you want is 5 commits back.
