Comment 1: You can't undo. The change has been made permanent and now
you're up to try and fix what you've done.
How to proceed depends on what you corrupted. If it's /home, your
fastest method would be to write a script that looks up the username in
the passwd file and sets the ownership down from there.
If you can't guess who the original owners should have been and you
really corrupted everything from / down, you're unfortunately better off
restoring from your backups. Make another backup first, restore the
system, and then do an incremental comparison to see what needs to be
restored, remembering of course that you don't want to restore the
corrupted ownerships. It's going to be ugly.
If you have no backups, you're going to have a really bad weekend.
