DCLI supports interactive shell mode which you can activate by using dcli +interactive.
Interactive mode supports drop-down autocompletion of namespaces, commands, command options, and option values in case of enumeration values. With DCLI interactive mode, you can also pass a short command if it is uniquely resolvable. For example, dcli> com vmware vmc vm list can also be run as dcli> vm list.
Interactive mode is also a quicker way to browse various namespaces and commands, as DCLI caches the list of namespaces and commands available on the server for faster access. DCLI interactive mode provides specific shell commands which can be accessed by running dcli> help.
You can change the prompt for DCLI interactive mode by using dcli +interactive +prompt <user-prompt> when entering interactive mode.
