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.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
