Samy_rio has asked for the wisdom of the Perl Monks concerning the following question:

G'day monks, I have a problem in File::DirWalk. My tried code as:

use strict;
use warnings;
use File::DirWalk;

my $folder = 'E:\test\foldersize\1-folder|E:\test\foldersize\2-folder|
+E:\test\foldersize\5-folder';
my $depth  = 3;

my @directory = grep!/^\s*$/, split/\|/, $folder;

my @folder;
for my $directory (@directory){

    my $dw = new File::DirWalk;

    $dw->onDirLeave(sub {
                my ($dir) = @_;
                return File::DirWalk::FAILED if ($dir eq $directory);
                push (@folder, $dir);
                return File::DirWalk::SUCCESS;
                            });
                                            
    $dw->setDepth($depth);
    
    $dw->walk($directory);
}

$,="\n";
print @folder;

Output as:

E:\test\foldersize\1-folder\Allworth\Copy of VTT
E:\test\foldersize\1-folder\Allworth\VTT
E:\test\foldersize\1-folder\Allworth
E:\test\foldersize\1-folder\Brepols\ARA
E:\test\foldersize\1-folder\Brepols
E:\test\foldersize\1-folder\Else_UK\KAST2
E:\test\foldersize\1-folder\Else_UK

But i need only last folder path. That is, 3rd depth folder path only.

E:\test\foldersize\1-folder\Allworth\Copy of VTT
E:\test\foldersize\1-folder\Allworth\VTT
E:\test\foldersize\1-folder\Brepols\ARA
E:\test\foldersize\1-folder\Else_UK\KAST2
E:\test\foldersize\2-folder\Allworth\VTT
E:\test\foldersize\2-folder\Brepols\ARA
E:\test\foldersize\2-folder\Else_UK\KAST2
E:\test\foldersize\5-folder\Allworth\VTT
E:\test\foldersize\5-folder\Brepols\ARA
E:\test\foldersize\5-folder\Else_UK\KAST2

How to acheive this? Any special function available in File::DirWalk itself? Thanks in advance.

Velusamy R.
