Hello,

First I want to thank you a lot for this elegant solution. I tested your code on a real life case and for some reason it doesn't work.

Here is the code:

 
#!/usr/bin/perl -w
use strict;
use warnings;
use Data::Dumper;

my @ar1=qw(F40_I_VBBG_RI50-FMVSS301n-2SR424M-HCH-D_01EK101.a3db    
           F40_I_VBBG_RI50-FMVSS301n-2SR424M-HCH-D_01EK101a.a3db 
           F40_I_VBBG_LR50-ECR17p-2SR424M-HCH-D_01EK101g.a3db 
           F40_I_VBBG_LR50-ECR17p-2SR424M-HCH-D_01EK101k.a3db 
           F40_I_VBBG_LR50-ECR17p-2SR424M-HCH-D_01EK101.a3db );

#my @lastversion = values %{{ map { /EK(\d+)\w?/, $_ } sort @ar2 }};

my %latest;

@latest{ /EK(\d+)\D/ } = $_ for sort @ar1;
my @lastversion = @latest{sort {$a <=> $b} keys %latest};

foreach (@lastversion)
{
#print "@lastversion\n";
print "$_\n";
}
#print Dumper(\%latest);

The correct output should be this:

F40_I_VBBG_RI50-FMVSS301n-2SR424M-HCH-D_01EK101a.a3db

F40_I_VBBG_LR50-ECR17p-2SR424M-HCH-D_01EK101k.a3db

After i run the script i just get the first name:

F40_I_VBBG_RI50-FMVSS301n-2SR424M-HCH-D_01EK101a.a3db.

I really can't tell what the problem is. I am asking again for your help.

Thank you in advance.
