Good morning, I'm new at all of this but managers want me to look at an Oracle alert log . I call this mail. I want to eliminate from mail.fil certain lines with numbers contained in file THIDSerrs. 

!/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 "@sub
+array \n"; 
This doesn't return anything!

This doesn't return anything! Looking to find common elements between two files and eliminate from one file (mail.fil)
