Thanks for the help everyone. This one looks like it will fit best into my script, however I'm having one more issue, and it's no doubt something really ridiculous I'm doing wrong.

I have the following code snippet:

#!c:/perl/bin/perl
use strict;
open (HYPERS, "< hypers.txt");
my @hypers = <HYPERS>;
chomp @hypers;
print "Hypers array: @hypers\n";
foreach my $line(@hypers){
$line =~ /([0-9a-f]+):([0-9a-f]+)$/i
    and my @range = map sprintf( '%x,',$_ ), eval "0x$1 .. 0x$2";;
    print @range;;

}

Output: 
Hypers array: 293F:2946

So I know the array is being read, but when trying to shove it into that regex it's coming out as '', almost like it's not there.

The HYPERS file looks like this:

293F:2946
