Hello Monks,

I'm in a bit of a bind here. I think I'm in over my head. I have large log files (2-3 GB) that have entries like this: 
2003-12-22 15:48:35     Local4.Error    192.168.1.2   
Dec 22 2003 20:48:25: %FW-3-106011: Deny inbound 
(No xlate) udp 4 dst inside:192.168.18.6/161

2003-12-22 23:52:00     Local4.Critical 192.168.1.2   
Dec 23 2003 04:51:50: %FW-2-108002: SMTP replaced >: 
out 192.168.36.223 in 192.168.11.12 
data: MAIL From: <123@hotmail.com>..

What I would like to do is get out the unique FW messages (ie %FW-3-106011 and %FW-2-108002) and when I print it out include just one of the log entries with it. For example I would like it to look like this: 
%FW-3-106011:

2003-12-22 15:48:35     Local4.Error    192.168.1.2   
Dec 22 2003 20:48:25: %FW-3-106011: Deny inbound 
(No xlate) udp 4 dst inside:192.168.18.6/161

I know this isn't correct, but I gave it a stab: 
use strict;
use warnings;

my $file = 'd:\PROGRA~1\Syslogd\Logs\syslog22Dec2003.txt';

open (FILE, $file) or die "Can't open $file: $!\n";
my (@lines);

while (<FILE>){
    push (@lines, $_) if /(\%FW\-\d-\d+)/;
    next unless $1 !~ /$1/; #my stupid logic
}

I appreciate any help.

Thanks,
Dru
