Thanks to all for the replies. All of the examples and suggestions will help me tremendously. I really appericate the help. I know that hashes are my friend (usually use them all the time) and will most likely use $mounts{$directory/$entry}++ to test for uniqueness. I just thought there might be a way to test for uniqueness within an array without doing a for loop or some other magic. Anyway, thanks again for the help.. Mitch (AKA: PerlMunger)
