Hi Monks, I was trying tag the record with maximum value. Here is my code so far:-

#!/usr/bin/perl
use List::Util qw(min max);


open(FH, $ARGV[0]) || die("Cannot open:$!");

while(<FH>) {

   if($_ =~ /\A(\S+)\t(\S+)\t(\S+)\t(\S+)\,(\S+)\,(\S+)/xmg) {

            #print "$1\t$2\t$3\t$4,$5,$6\n";

           if(($5 == $5) && ($6 == $6)) {
                               
                push @list, $4;

                $min = min @list;
                $max = max @list;
                
                if($4 == $max) {

                #print "$1\t$2\t$3\t$4,$5,$6\n";
                print "$max\n";
                }
           }
   }
 }

Here is the type of output I am trying to achieve :-

62556    63635    y    single,andrew,JJ113954
63868    63897    h    1,morgan,JJ113955
68766    69005    j    end,morgan,JJ113955
81099    81630    y    single,flintoff,JJ113952
126185    126699    s    single,austin,JJ113956
135356    135449    3    1,peter,JJ113952
135588    136297    8    2,peter,JJ113952
158146    158367    i    end,peter,JJ113952
