You can display help for each namespace and command by using the --help command-line option.

Because the available commands depend entirely on the services that are available in the vCenter environment that you are targeting, you must include the server for accurate help information. For VMware Cloud on AWS, the available commands depend on the services that are available in the REST API that you are targeting.

Help returns the following information for a command.
