in reply to sorting domains by extention

You don't need a full sort, all you want is to put the domains in the proper buckets. Here's my solution:

#!/usr/bin/perl use strict; use warnings 'all'; my @regexes = map {qr /\.$_$/} qr {co\.uk}, qr {com}, # No need for the [\w\-] prefix. qr {pl}, # qr {uk\.com}, # This one already gets grabbed by \.com ; my @domains = qw { foo.com weirdext.za bar.uk.com blah.co.uk perl.pl zzzz.co.uk }; my @buckets = map {[]} @regexes, 1; DOMAIN: foreach my $domain (@domains) { for (my $i = 0; $i < @regexes; $i ++) { next unless $domain =~ qr /$regexes[$i]/; push @{$buckets [$i]} => $domain; next DOMAIN; } push @{$buckets [-1]} => $domain; } print "$_\n" for map {@$_} @buckets; __END__ blah.co.uk zzzz.co.uk foo.com bar.uk.com perl.pl weirdext.za
