It's surprisingly mellow thrash-wise, actually. I just do

 

#SETUP DELETED, CODE WON'T RUN

my @file1 = <FILE1>;
my @file2 = <FILE2>;

my $lc = List::Compare->new(\@file1, \@file2); 

my @file1only = $lc->get_Lonly; 
my @file2only = $lc->get_Ronly; 

print OUT "Files that exist only in FILE1:\n";
print OUT "IGNORING FILES WITH Tmp OR Temp IN PATHNAME!!!\n\n";
foreach my $file1(@file1only) {
    unless (($file1 =~ "Tmp") or ($file1=~"Temp")) {
        print OUT $file1;
        
    }
}

print OUT "\n\n";

print OUT "Files that exist only in FILE2:\n";
print OUT "IGNORING FILES WITH Tmp OR Temp IN PATHNAME!!!\n\n";
foreach my $file2(@file2only) {
    unless (($file2 =~ "Tmp") or ($file2=~"Temp")) {
        print OUT $file2;
    }
}

and it takes less than a minute to run on my box here at work.

Unfortunately, we're an all-Windows shop. I've managed to infiltrate a couple of FreeBSD boxes into the test department (cool network tools and a neato disk imaging system called Frisbee), but it's hardly worth moving all of the files over there and back just to save a few seconds using "sort" instead of List::Compare.
