I'm looking to find common lines between two files (mail.fil) and (THIDSerrs). I then want to eliminate the common lines from the one file, mail.fil. 

#!/usr/local/perl-5.12.3/bin/perl
use strict;
use warnings;
open FILE,"< mail.fil";
my @oralines=<FILE>;
close FILE;
#print @oralines;
open FILE,"<THIDSerrs";
my @errs = <FILE>;
close FILE;
#print @errs;
my @subarray = ();
foreach my $oralines(@oralines)
{
  foreach my $errs(@errs)
  {
  push @subarray, $oralines if grep /$errs/, @oralines;
  }
}
print "@subarray \n";

Hope this is more readable - I'm new at this.
