I wrote this simple script after some reading online.

To achieve fastest execution time, I want to have the number of jobs == arraysize. (any array in script for looping repeating process) I guess the other words, is instead of running stuff serially (one after the other), i have them in parallel to minimize time taken.

So in this case I wanna delete a directory, delete the directory1 in (/user/home/directory1/), but i am clueless why it does not work, all the files and subdirectories still there. Does the script automatically assign each files/subdirectories to each children?

Let me know if I have overlooked stuff. I am ready to learn . Thank you . :) 

#! /usr/bin/perl
 
use Parallel::ForkManager;
 
$directory1 = "/user/home/directory1/";
 
my $pm = Parallel::ForkManager->new(10);
 
my @files = glob("$directory1/*");
my $number = scalar(@files);
 
for (my $i = 0; $i < $number; $i++) { 
 
    $pm->start and next;
    
    system ("rm", "-fr", $files[i]);
    exit(0);
                
  $pm->finish;
}

$pm-> wait_all_children;
