   (There's a difference between these two cases, cp ought to have the same   
   base set of features on different systems and implementations, as   
   specified by IEEE 1003.1, while ifconfig isn't in there, so unless it's   
   the same utility or a fork of the codebase, there's no guarantee that   
   it'll share features, option names, syntax or output formats.   
      
   Kind of like killall isn't specified and can either kill all processes   
   or kill processes by name, depending on the implementation.)
