in reply to array and hash

Boy, did you pick the right language. Try:
my %hash; for my $element (@array) { $hash{$element} = <some command>; } ... for $element (@array) { # Keep the same order as the original array print "For $element, output was $hash{$element}\n"; }
This would be much harder in something that wasn't perl.

[Corion]: Discipulus: Yeah - but when writing Perl to save time (instead of having fun), it helps to look whether you're actually saving time ;) Why spend 5 minutes doing manually what you can spend three years automating? ;)
[Corion]: choroba: Oh, yeah :-D
