I'm probably missing something, but what's wrong with?:
sort {$b <=> $a} @array;

I have an array of strings whose members consist of a number

e.g.
1,fresh
2,testurl
I want to sort by descending numerical order according to the number
part so I made this sort subroutine
sub by_counter_field {
my($a, $b) = @_;
$a =~ s/^(.*?),.*/$1/g;
$b =~ s/^(.*?),.*/$1/g;
if ($a > $b) { -1 } elsif ($a < $b) { 1 } else { 0 }
}
and sorted it with
sort by_counter_field @array;
and it didn't work.
I've also tried replacing
if ($a > $b) { -1 } elsif ($a < $b) { 1 } else { 0 }
with
$b <=> $a
and it still didn't work.
I also tried this
sort { ($b =~ /(.*?),.*/)[0] <=> ($a =~ /(.*?),.*/)[0] } @array;
and it didn't work either.
I can't figure it out for the life of me
Any assistance would be deeply appreciated.
Regards
