Well, the OP didn't ask for that, but if he wants it, (and this is one of the reasons I love perl) it's an easy fix :)

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1147112

use Inline::Files;
use strict;
use warnings;

my %id;

$id{ s/;.*//r } .= $_ for sort <FILE1>;
print delete @id{ <FILE2> }, values %id;

(with another simplification thrown in)

Nice!

Ok excuse the stupid question, but perl is new to me.

I have file names FILE1 and FILE2 I also tried with __FILE1__ as read here (http://search.cpan.org/~ambs/Inline-Files-0.69/lib/Inline/Files.pm)


But I keep getting errors

These are warnings obviously, but I get no output

The module Inline::Files is just used to make a self-contained program for testing purposes. Use perl's normal open function for actual usage.

See "perldoc -f open".

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1147112

use strict;
use warnings;

my %id;

open my $fhdata, '<', 'File1' or die "$! opening File1";
open my $fhorder, '<', 'File2' or die "$! opening File2";

$id{ s/;.*//r } .= $_ for sort <$fhdata>;
print delete @id{ <$fhorder> }, sort values %id;

close $fhdata;
close $fhorder;

Where the file named "File1" contains your first file, and the file named "File2" contains your second file.
