Syntax

Parameters

-delim delimiter: (Optional) Specify a delimiter to separate data in the output.
-nohdr: (Optional) Suppress the headings in the output.
-filtervalue attribute=value: (Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are displayed.
-filtervalue?: (Optional) Displays a list of valid filter attributes.

-bytes: (Optional) Displays all capacities as bytes.
object_id | object_name: (Optional) Specifies the name or ID of an object. When you use this parameter, the detailed view of the specific object is returned and any value that is specified by the -filtervalue parameter is ignored. If you do not specify the object_id | object_name parameter, the concise view of all objects that match the filtering requirements that are specified by the -filtervalue parameter are displayed.
