       Specifies the action to perform on the object.  The set of possible actions depends on the
       object type.  As a rule, it is possible to show (or list ) objects, but some objects do
       not allow all of these operations or have some additional commands. The help command is
       available for all objects. It prints out a list of available commands and argument syntax

       If no command is given, some default command is assumed.  Usually it is list or, if the
       objects of this class cannot be listed, help.


       Exit status is 0 if command was successful or a positive integer upon failure.
