You're welcome, and kudos to  MacGyveR for remembering about the : which 
allows you to combine the two commands.

Now that the disaster has passed may I suggest that you look a little 
more closely at the way you back up and restore?  It should be possible 
to preserve users and groups during that process and most commands have 
flags/switches/options designed for doing this.  This is often not the 
default behaviour (which always seemed bizarre to me) so you have to 
specify to keep permissions, owner and group, often with a -a or -A option.

If you had a lot of users it becomes important as restoring appropriate 
permissions would be tedious.  In addition, it is a rather sweeping 
assumption that all the files under a user's home directory do in fact 
belong to the user's login group.  (Generally true but users may, for a 
variety of reasons, choose to change the default group of a file or 
directory to give other users and programs more or less access to it.)
