       The names of all objects may be written in full or abbreviated form, for example **stats **can be
       abbreviated as **stat **or just **s.**


   _COMMAND_
       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 conventions.

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


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