## [*COMMAND*](#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 objects of this class cannot be listed, **help**.

# [EXIT STATUS](#EXIT_STATUS)

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