DCLI supports interactive shell mode which you can activate by using dcli +interactive.

Interactive mode supports tab completion of namespaces, commands, command options, and option values in case of enumeration values. With DCLI interactive mode you can also pass a partial command if it is uniquely resolvable. For example, dcli> com vmware vcenter 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.
