in reply to Bad file descriptor after vmran command using system()

You're using system() incorrectly, specifically its return value. The error message is misleading, $! contains junk from a previous system call. Using system() correctly is very difficult, have a peek at the official documentation. All Perl built-ins suck, this one sucks the most.

Instead use autodie for proper error handling, it's tested and you get nice default error messages:

use autodie qw(:all); # replaces system() system $command; # implicit error handler

    Low level functions are low level functions, this doesn't mean they suck, they're just low level
