Dear Experts, I have been testing a simple portion of a script that is supposed to become part of something else and suddenly run into a problem: after I delete the Vmware Workstation snapshot using system() I get Bad file descriptor message. But the snaphot itself is successfully deleted! And the same command from the command prompt works all right. Here is my code:

#!/usr/bin/perl

use Time::HiRes;

use File::Path;

use warnings;

use strict;

$|=1; 

sub spin {

my ($arg) = @_;

for (my $x = 0; $x <= $arg; ++$x) {

  foreach (("-", "\\", "|", "/")) {

    print $_; Time::HiRes::sleep (0.1); print "\b";

  }

} 

#print " \n";

}

my $j = 0;

my $base = "C:/Users/User/Documents/Virtua~1/";

print "Enter VM name: ";

my $vm = <STDIN>;

chomp ($vm);

print "Enter Snapshot to be deleted: "; 

my $snapshot = <STDIN>;

chomp ($snapshot);

my $vmware_dir = "C:/Progra~2/Vmware/VMware~1/"; 

my $command = "$vmware_dir" . "vmrun -T ws deleteSnapshot " . "$base" 
+. "$vm" . "/" . "$vm" . ".vmx " . "$snapshot";


if ( (my $pid = fork() ) == 0) {

     do { sleep 0.5; spin($j) } while 1;  

} 

else {

     print "Deleting snapshot...";

     system ("$command") or die "Operation failed: $!\n";

     kill 9, $pid;

     waitpid $pid, 0;

}

print "\bDone!\n"; # Never gets here!

And this is what I get in the end:

Deleting snapshot...\Operation failed: Bad file descriptor

As I said, the snapshot gets deleted, but there is an error message and the background spinning never ends.
Thank you in advance!
