Command line syntax
CLI input is case-insensitive except when otherwise noted. The general CLI syntax format is as follows:
<subcommand> <managed element> <parameters> [<options>] [<properties>]
Item Description
subcommand Operation performed on a managed element
managed element Management entity being operated on
parameters Command extensions for a particular management operation
options Attributes used to customize or control command execution behavior such as output
format, quiet-mode, and others
properties One or more name or value pairs that are accessories to the command operation,
mainly for set and add operations
Example: ->add user mark password=asdf89g fullname="Mark Smith" enabled=true
In the above example, add is the subcommand, user is the managed element, mark is a required
parameter for the operation, password is a required property, and fullname and enabled are
optional properties.
Depending on the specific command being executed, certain parameters or properties might be required.
For example, when adding a new user, both a parameter representing the user name, as well as a
password (in the form of a property) are required to be specified. All other user properties are optional at
the time the user is added. In general, the properties are in the format name=value, and more than one
property is separated by a space.
Parameters
Parameters are command extensions that provide extra information needed for the execution of a
particular command. Whether or not a parameter is required depends on the specific command being
executed. For example, the show user command has an optional parameter, which represents the user
name if the user instance is being managed. If show user is entered, then a summary listing of all users
is shown. However, if the optional parameter (user name) is provided, only a single user instance is
displayed, for example, show user paul.
Some commands require that a parameter be specified, for example, the add user command. The
required parameter is the user name (add user jake), and if the username is not provided, an error
message displays indicating that a required parameter is missing.
Options
Options enable users to control certain behavior characteristics available during the command execution.
Some examples of options include controlling output format and specifying a quiet mode for
suppressing interactive prompts that would normally require input from the user.
Options are distinguished from other command line elements by using a hyphen (-) in front of the option.
Option arguments are required or optional depending on the option being specified. For example, the -
output option requires an argument, which is a list of one or more output format attributes. However,
the -quiet option does not require any arguments to be specified.
The general format of a CLI option is as follows:
