 I don't mean to be picky, but...


use strict;
use warnings;

my ($first, $last);

open CONF, "</etc/adduser.conf" or die;
while (<CONF>)
    next unless /^(FIRST|LAST)_UID=(\d+)/;
    $1 eq "FIRST" and $first=$2;
    $1 eq "LAST" and $last=$2;
close CONF;

die unless defined($first) and defined($last);

while (my ($name,undef,$uid,undef)=getpwent())
    if ($uid >= $first and $uid <= $last)
        print $name, "\n";

 If it breaks, you get to keep as many pieces as you want.
