Hi everyone,
Thanks for all the tips and guide. I finally manage to work around the code and solved my problem. I am using a "IF" and "While" within a "While".
Below are my code and it works well. I am not too sure if by running in this flow will it take up resourses or not as it will compare 60,000 of records in the file.
Hope that this discussion and codes helps other who seek wisdon. 

open(file1,"file1.txt") || die ("cannot open file");

while (<file1>)
   {
      chop();
      $REC     = $_;
      @LINEREC = split(/\,/,$REC);
      $data1 = @LINEREC[0];

   open(file2,"file2.txt") || die ("cannot open file");

   while (<file2>)
     {
        chop();
        $REC     = $_;
        @LINEREC = split(/\,/,$REC);
        $data2 = @LINEREC[1];

        if ($data1 eq $data2)
           {
             print "$data1\n";
           }

     }
 }
close file1;
close file2;
