Yeah, definitely way easier Mr. Anonymous.

Now I'm just working on filtering out duplicate results and I should be good, hurray!

What's going on: I've ssh'd onto my localhost, ls the desktop and taken those items and put them into an array I hardcoded a short list of items and I am comparing them with a hash to see if anything is missing from the host (See if something from a is NOT in b, and let me know). So after figuring that out, when I print out the "missing files" I get a bunch of duplicates (see below), not sure if that has to do with how the files are being checked in the loop, but I figured the best thing to do would be to just sort out the data and eliminate dupes. When I do THAT, and print out the fixed data, only one file is printing, two are missing. Any idea why?

    #!/usr/bin/perl

    my $hostname = $ARGV[0];

    my @hostFiles = ("filecheck.pl", "hostscript.pl", "awesomeness.txt
+");
    my @output =`ssh $hostname "cd Desktop; ls -a"`;

    my %comparison;
    for my $file (@hostFiles) {
    $comparison{$file} +=1;
    }

    for my $file (@output) {
    $comparison{$file} +=2
    }

    for my $file (sort keys %comparison) {
    @missing = "$file\n" if $comparison{$file} ==1;
    #print "Extra file: $file\n" if $comparison{$file} ==2;
    
    print @missing;
    }

    my @checkedMissingFiles;

    foreach my $var ( @missing ){
       if ( ! grep( /$var/, @checkedMissingFiles) ){
          push( @checkedMissingFiles, $var );
          }
       }
     print "\n\nThe missing Files without dups:\n @checkedMissingFiles
+\n";
