in thread Array size issue

Sorry.... could have fooled me considering the logic in your original post.

If I break your code down into pseudo-code it reads like this:

Part of the art of getting good answers on Perl Monks is being concise about your questions and not leaving what you are after up to the interpretation of the reader.

Once again I will attempt to extrapolate what you are after. You code will work better if you don't put the print lines in and change the exit for last.

    I apologize for not being clear and I do appreciate all the valuable input I get from this community.

    Without the print statement I will not be able to debug my code. I want to make sure my array is carrying the proper line/data before attempting to process it. This is what I got after reading all the comments. I think I'm missing a small piece and I can't figure it out. 

    open my $tailf, "tail -f $logFile |" or die;
while (<$tailf>) {
    chomp;
    my $line = $_;
    if($line =~ m/ on $ipaddress/)
    {
        if (scalar(@matches) <= 2){
            push(@matches, $line);
        }        
        else {
            last;
        }
    }
}

foreach $line (@matches){
     print "$line\n";
}
        
close $tailf;

      myself I'd rewrite two of your "ifs." 

      next unless ($line =~ m@on $ipaddress@);
last if scalar(@matches) >= 2;

      At least to my eye that's more readable.
