If your file names are consistently like your example, use split : 

use strict;
use warnings;

opendir( DIR, "/home/Lhamo/files" ) or die "painfully: $!";
my @files = readdir DIR;
closedir DIR;

for ( @files ) {
    next if ( $_ eq '..' );
    next if ( $_ eq '.' );
    my ( $filename, $code_number ) = split( /./, $_, 2 );
    print "$code_number\n";
}

I made a mistake. I don't know where, but I always do. I haven't tested this code. Someone will point it out shortly :) In any case, you get the idea.
