I'm sure this is a simple question but how do I sort the keys of a hash in numeric order if the keys are of the form Drive0, Drive1 ... Drive10, Drive11, etc.

I have tried the following:

sub mysort { $a <=> $b; }
foreach $i ( sort mysort ( keys %myhash ) ) { print "$i\n"; }

[download]

This only complains that Drive1 is not numeric.

If I use the standard ASCII sorting then it gets sorted Drive1, Drive10, Drive11, Drive2, etc.

Thanks in advance for the help.
