Hello everyone,
I'm attempting to parse the output of 'show access-list' over a period of days to determine if a line in the access-list does not receive a hit over a period of time. Please see my earlier post: Parsing cisco log file

Below is the code I've come up with, I'm running into trouble with the last portion where I compare lines that have not received matches during day one to lines that haven't received matches on day two. I get nothing at all for output, any thoughts on where I have screwed up or how I can do this better would be much appreciated.

We're storing the output of sh access-list from a cisco #router in a file once a day for 30 days. This script will eventually look at all 30 files and output the access-list entries that have not recieved a match in all 30 files and therefore can be removed. 

#/usr/bin/perl
#Prompt for the files we want to compare, for now just two

print "Enter filename that contains output of show access <list\n";
chomp ($aoutput = <STDIN>);
print "Enter the second file\n";
chomp ($aoutput1 = <STDIN>);

#Open our files
open (IN, $aoutput) || die "Couldn't open $aoutput $!";
open (LOG, ">>matches.txt") || die "Couldn't open matches.txt $!";
open (IN1, $aoutput1) || die "Couldn't open $aoutput1 $!";

#Push each line in file 1 that does not get any matches into an array

while (<IN>){
   push @aoutput unless /matches\)$/;
   }

#Push each line in file 2 that does not get any matches into an array

while (<IN1>){
   push @aoutput1 unless /matches\)$/;
       }

#See if the lines that didn't get matches on day 1
#didn't get matches on day 2 as well
#Gotta be a better way to do this?

while (<@aoutput>){
   $linetemp = grep {/$_/i} @aoutput1;
      if ($_ = $linetemp)
      {
      print $_;
      } 
  }
