This might be a duplicate, I just didn't happen to find one.

Basically the scenario is: there were some minor changes to a file in some commit, and now the file has been modified even more (to add new features, etc.).

What I would like to do is to automatically undo (if possible) the changes to the file in that commit, without actually going back to an old revision of the file; i.e., whatever the diff for that commit was, the reverse of it should be applied to the current version. The result is a new "fixed" version of the latest file.

I realize it isn't always possible for a computer to do this, but when the future changes after the bad commit are completely unrelated and in a different location, it should be possible. How can I do this?

find out the commitish you want to undo and revert it:

$ git revert 53ab103e8f

will revert commit 53ab103e8f (by creating a new entry in your repository, that explicitely reverts that change; if there are problems with reverting, you will be asked to manually resolve the conflict)

+1 D'oh, I didn't know that's what revert does, haha. I thought it goes back to that commit. Thanks!
