in reply to Everybody loves not using File::Find

Here comes the version with File::Find, although "Everybody loves not using File::Find" :-) (I only tested it on Win. At home, no UNIX around. I expect some small modifications to satisfy UNIX, such like symlinks etc.) 
use File::Find;
use Data::Dumper;

my $files = {};
find(sub {wanted($files);}, "c:/perl58");
print Dumper($files);

sub wanted {
    if (($_ ne ".") && ($_ ne "..")) {
        insert(shift);
    }
}

sub insert {
    my @elements = split("/", $File::Find::name);
    my $parent = shift;
    my $index;
    foreach ($index = 0; $index <= $#elements; $index ++) {
        if (($index == $#elements) && (-f $_)) {
            $parent->{$elements[$index]} = $File::Find::name;
        } else {
            if (!defined($parent->{$elements[$index]})) {
                $parent->{$elements[$index]} = {};
            }
            $parent = $parent->{$elements[$index]};
        }
    }
}

    ++pg for headspin value ! This code does run on linux , a small mod to &wanted to make it symlink safe(r)

    if (($_ ne ".") && ($_ ne "..") && (! -l $_)) {

    However when the hash is unrolled, the first key is null, and keys are generated all the way down to the actual search base.

    eg: running this script on  /usr/local/html/users/me
returns
VAR1='' => { 
    'usr'=> { 
        'local' => {
             'html' => {
                'me' => {
etc,etc. Before the real search begins.

    So to accomodate for that we can change the assignment to @elements

    @elements = split("/" , substr($File::Find::name, length($ARGV[0])));

    Obviously that shift @ARGV had to be replaced with $ARGV[0] , which might be better done assigning to a (heaven forefend) global.
