You are right. I am using Powershell but CMD is standard.

I found this alternative for CMD:

wmic path win32_computersystemproduct get uuid #works in CMD

Still I do not get the principle from Perl for CMD

my $UUID = system ('wmic path win32_computersystemproduct get uuid');

No PS on macOS. I meant the way to call a command from Terminal works out-of-the-box. This works on macOS:

my ($UUID) = `ioreg -d2 -c IOPlatformExpertDevice` =~ /^.*\bIOPlatform
+UUID\b.*"([^"]+)"\s*$/m or print "failed to parse ioreg";
