Hello! I want to match two large data files to match and print only identical id data.

file1:

ABS0056

ABS0057

ABS0058

ABS0059

...........

file2:

id “ABS0056”; name “SAM”;

id “ABS0059”; name “JOE”;

id “ABS0060”; name “MARY”;

id “ABS0057”; name “BILL”;

id “ABS0057”; name “BILL”;

id “ABS0056”; name “SAM”;

id “ABS0065”; name “RONIE”;

id “ABS0061”; name “STEPHAN”

id “ABS0057”; name “BILL”;

id “ABS0056”; name “SAM”;

........

I used awk to remove semicolon and inverted commas. These two columns are separated by tab. So my file looks like this:

file3

ABS0056 SAM

ABS0059 JOE

ABS0060 MARY

ABS0057 BILL

ABS0057 BILL

ABS0056 SAM

ABS0065 RONIE

ABS0061 STEPHAN

ABS0057 BILL

ABS0056 SAM

..............

I want my output in following data format:

ABS0056 SAM

ABS0057 BILL

ABS0059 JOE

I have tried using code as below:

#!/usr/bin/env perl

use strict;
use warnings;
open FILE1, "< file1" or die;
my $keyRef;
while (<FILE1>) {
   chomp;
   $keyRef->{$_} = 1;
}
close FILE1;

open FILE3, "< file3" or die;
while (<FILE2>) {
    chomp;
    my ($testKey, $name) = split("\t", $_);
    if (defined $keyRef->{$testKey}) {
        print STDOUT "$_\n";
    }
}
close FILE3;

Thanking in advance
