chown -R under root directory
Hi
I executed command "chown -R xxx:xxx /" with user root... and it was too late when I found the mistake. Ownership of some files under the root directory had already become xxx:xxx. Is there a way that can recovery the ownership of all my files back to the point where they were? I really thanks.

Only if you have a backup and restore that. Else you can do it manually, but that can result to be impossible. Maybe if you have a "twin" machine where you can check things at least for system directories like /dev /etc and so on.
For user data you might have to ask around.

I don't have a backup... so I just re-install the OS.
