Did you read my node? Did you read the sort documentation? Did you look at my example and look how you could adapt it to your needs?

Please take another look at the sort documentation. Please look at my example (taken from there) and see how you can adapt it to what you need.

@articles = sort {$a cmp $b} @files;

It's hard to help if the question keeps moving!

update: the following is wrong :-(

Each element in your follow up array is the reverse of those in the origninal. (There's a hint in there!)

With that observation and another look at the docs I was able to sort the array in the order you're looking for using the method suggested by Corion.

You didn't say my $sort = (... either.

update 2:

Pursuing the reverse theme, perhaps you could consider an intermediate step:

#!/bin/perl5

use strict;
use warnings;
use Data::Dumper;

my @sort = qw(
  05-11-2006 
  01-01-2005
  04-12-2005
  22-03-2005
);

my @reversed = map {
  join '', 
    substr($_, 6), 
    substr($_, 3,2), 
    substr($_, 0,2)
} @sort;

print Dumper(\@reversed);

Now you changed your requirements in the middle - which incidentally is mostly annoying. If they're as in the OP, then my reply still applies.

Or else you will have to provide a suitable sort sub, possibly exploiting one of the various sorting techniques often references here and elsewhere. Try checking for example:

• Complex sorting,
• Understanding transformation sorts (ST, GRT), the details,
• Resorting to Sorting,

from the Tutorials section. A recent post of mine using a form of Guttman-Rossler is this. In this case you should have fixed length fields and it should be even easier for you to recover the original data with a single substr.
