List forms for system, exec, etc
  Perl's system and exec functions can take lists instead of strings:
  $filename = "a file containing spaces";
  # Won't work
  system "/bin/rm $filename";
  # Better way
  system("/bin/rm", $filename)==0 or die "rm failed";
  # Exec example
  exec "/opt/bin/doit @args";
  # Better
  exec "/opt/bin/doit", @args;
  die "exec failed";
