Personally, I'd skip Perl's built-in sort for this and look at using Sort::Naturally - it handles just this case cleanly and simply, and will leave your code readable. e.g.: my @strings = ( '999 zzz', '111 zzz', '111 aaa', '999 aaa', ); print join "\n", Sort::Naturally::nsort @strings; ... would get you the output I think you want, i.e.: 111 aaa 111 zzz 999 aaa 999 zzz -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
