  Perl and the shell
  Perl doesn't actually use the shell if it can avoid it.
  Expands shell globs like '*' and '?'.
  Sends them explicitly as a list, so 'a ..' is one argument.
  Doesn't prevent problems where globs expand to unexpected program arguments.
  Doesn't allow you to specify arguments explicitly.
