I have two lists of files. File list A is a list of files that have been transferred. File list B is a list of all files in a given directory. What I want to find is an item from list B that does not exist anywhere in list A. I just can't quite get my head around how to approach the problem.

@rray1=('one','red','orange','brown','green','blue','scarlett','fourte
+en');
@rray2=('red','orange','yellow','green','blue','indigo','violet');

foreach my $check (<@rray1>) {
        foreach my $item (<@rray2>) {
                if ($check ne $item) { 
                    <do something>
                }       
}#close foreach

The problem with this approach is pretty obvious: 'one' does not match anything in the second list, which would be what I want. However, 'red' matches 'red' but also shows as not matched on everything else. Basically, I think what I want is to find a string wherever it is in an array. I've tried playing with hashes (also grep) on this to see if the solution might be in that direction, but I'm at a loss as to where to go from here. I just need a prod in the right direction, not a full-blown solution.

thanks
