I tried a new code and realized that file2 (similarly file3)contains more than 18000 rows and it has repeating values of ids and names

I tried following code to get desired output:

#!usr/bin/env perl

#use strict;
use warnings;

open (FILE1,"< file1”);
while (!eof(FILE1))
{
chomp ($element1 = (<FILE1>));
open (FILE3"< file3”);
while (!eof(FILE3)
{
$element2 = (<FILE3>);
if ($element2 =~ /$element1/)
{print $element2;}
}
}

This code is matching but printing values in replicates (for example: output has ABS0057 BILL = 3 times, ABS0056 SAM = 3 times) since file3 itself contain replicate values. I want to print one in output that shows match (say ABS0057 from file1 matches ABS0057 BILL from file3, output should print just one ABS0057 BILL)
