People who are less confident with technology almost never try out things in GUIs in case they break. Those more confident tend to click on things just to see what they do. If a CLI user knows that they can type "--help" at the end of a command to start learning what it can do, I think that's a lot more "discoverable" than GUIs for less confident people.

Although what situation are you in where a not-confident person is even using a CLI?
