Question

I’m looking for a logical (not additional module) to sort by such format. I have a list of strings which looks like:

asdadasBBBsfasdasdas-0112
asdanfnfnfnfnf222ads-1210

etc.
I cant just sort by the numbers, because, for instance: 812 > 113 (812 = August 2012, 113 = January 2013, so its incorrect)

any good strategy??

thanks,

A schwartzian transform would be a huge waste here. This similar construct whose name I can never remember would be way better.

my @sorted =
   map substr($_, 4),
    sort
     map substr($_, -2) . substr($_, -4, 2) . $_,
      @unsorted;

Using the match operator instead of substr:

my @sorted =
   map substr($_, 4),
    sort
     map { /(..)(..)\z/s; $2.$1.$_ }
      @unsorted;
