in reply to Sorting on Section Numbers

Of course, there is a module on CPAN which does what you want! It's called Sort::Versions, available from and it basically does what you want:

use strict;
use Sort::Versions;

my @sections = qw(2.1.7 2.2 3.4a 2.13 1 2);
@sections = sort versions @sections;
print "@sections\n"; # prints "1 2 2.1.7 2.2 2.13 3.4a"
Hope this helps! Leon

    Unfortunately, this module fails for some simple cases:

    use Sort::Versions; print join(" ",sort versions qw(1.2a 1.10a)),"\n";
    1.10a 1.2a

    Note that this matches the behavior described in the module's documentation, but I think it isn't what most people would want.
