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

In order to go to a previous commit version of the file, get the commit number, say eb917a1 then

git checkout eb917a1 YourFileName

If you just need to go back to the last commited version

git reset HEAD YourFileName
git checkout YourFileName

This will simply take you to the last committed state of the file
