Dear Monks

I would like to sort fileswhose name are for examples : M3_output_ZGZ22_02_20061022_duration_200mn_comptage_60.txt

I have built the following sub routine:

use strict;
use File::Copy;

sub files_sort {
    my $first_number; 
    my $second_number; 
    if ($a =~ /(\d+)_(\d+)_duration_(\w+)_comptage_(\d+).txt$/){
        $first_number = $1; 
    }
    if ($b =~ /(\d+)_(\d+)_duration_(\w+)_comptage_(\d+).txt$/){
        $second_number = $1; 
    }
    if ($1 < $2){
        -1
    }
    elsif($1 > $2){
        1
    }
    else{
        0}
}

my @TXT = glob("*.txt");
@TXT = sort files_sort @TXT;

Is that OK ? Thanks

Update: thanks to pisni for correcting my mistake, I just want to order the list by the number 02, 04, 12, not the date (20061022).
