Hi Thanks.Below is the code i tried but it does not print anything to the STDOUT. 

    #!usr/bin/perl
      use strict;
      use warnings;

      my ($infile1,$infile2) = @ARGV;
      open (IFILE1, "<", $infile1) || die "Cannot open        $infile1
+:$!\n";
      open (IFILE2, "<", $infile2) || die "Cannot open $infile2:$!\n";

     my @array1;
     my %hash1;
     my $str;
     while (<IFILE1>) {
         @array1 = split (" ", $_);
         $str = $array1[0]."\t".$array1[1]."\t".$array1[2];
     $hash1{$str} = 1;
    }
    close IFILE1;
     my @array2;
     my $string;
    while (<IFILE2>) {
        @array2 = split (" ", $_);
        $string =  $array2[0]."\t".$array2[3]."\t".$array2[4];
        #print "$string\n";
        if (exists($hash1{$string})) {
          print "$string\n";
        }
    }
    close IFILE2;
