Why would you do a full sort just to find the maximum value?

    Its just what I though of first. You could also do:
    use strict; use warnings; use List::Util qw(max); my %prns; while (<DATA>) { my ( $printer, $num, $cmd ) = split /:/; $prns{$num} = $printer; } print "Highest numbered printer is $prns{max (keys %prns) }\n"; __DATA__ M08_amvpss09_MEDIP :275:lp -damvpss09 M07_amvpss09_MEDIP :279:lp -damvpss09 M09_amvpss09_MEDIP :278:lp -damvpss09 M01_amvpss09_MEDIP :2:lp -damvpss09 M04_amvpss09_MEDIP :1000:lp -damvpss09
    Something line FunkyMonk's suggestion would work as well.
