.I 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
.B show
(or
.B list
) objects, but some objects do not allow all of these operations
or have some additional commands. The
.B help
command is available for all objects. It prints
out a list of available commands and argument syntax conventions.
.sp
If no command is given, some default command is assumed.
Usually it is
.B list
or, if the objects of this class cannot be listed,
.BR "help" .

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