ppnair has asked for the wisdom of the Perl Monks concerning the following question:

I have written a perl code for processing file 'Output.txt' which has below Content.

new.example.com 28

new.example.com 28

example.com 28

example.com 29

example.com 29

example.com 29

example.com 29

orginal.com 28

orginal.com 29

orginal.com 30

orginal.com 31

expand.com 31

And file 'domain.txt' has list of domain Names which i need to match against File 'Output.txt'

new.example.com

example.com

orginal.com

test.com

new.com

I could manage to write PERL code like this 

 #!/usr/bin/perl
    use strict;
    open(LOGFILE,"Output.txt") or die("Could not open log file.");
    my $domain_name = 'domain.txt' ;
    open(DOM, $domain_name);
    my @r_contents = <LOGFILE>;
    close(LOGFILE);    
    while(<DOM>) {
        chomp;
        my $line = $_;
        my @lowercase = map { lc } @r_contents;
        my @grepNames = grep  /^$line/, @lowercase;
        foreach (@grepNames) {
            if ( grep  /^$line/, @lowercase ) {
                $domains{lc($_)}++ ;            }
        }
    }
    
    close(DOM) ;    
    foreach my $domain (sort keys %domains) {
        my %seen ;
         ($Dname, $WeekNum) = split(/\s+/, $domain);
         my @array1 = grep { ! $seen{ $_ }++ } $WeekNum;
        push @array2, @array1;
        my @array4 = "$domains{$domain} $domain" ;
        push @matrix,@array4 ;
    }
       printf "%-10s %-25s %-25s\n", 'DoaminName', "Week $array2[0]" ,
+"Week $array2[1]","Week $array2[2]";
       print " @matrix \n";

      Nice work on processing the Output.txt file. However, if I'm understanding the OP correctly, the contents of domain.txt are used to filter the contents of Output.txt, such that expand.com will not appear in the final output when using the OP's shown data sets. Given this, perhaps something like the following additions are needed:

      ...

open my $fh2, '<', 'domains.txt' or die "could not open domains.txt: $
+!\n";
my %domains = map { chomp; $_ => 1 } <$fh2>;
close $fh2;

open my $fh, "<", "output.txt" or die "could not open output.txt: $!\n
+";

my %data;
while (<$fh>) {
    chomp;
    $_ =~ m/(.*?)\s++(\d++)/;
    next unless $domains{$1};

...

      Thank you very much for the help.

      But 'Output.txt'have got dynamic data.The week Number Will keep on change when ever i pull data from Maillog for current month.

      print "Domain/WeekNumber\tWeek28\tWeek29\tWeek30\tWeek31\n"; and for my $week (qw(28 29 30 31)) will not work for me since the week number chnages every month.
