Not CLI commands but system calls. Technically, in that sense, both commands and desktops abstract system calls. It's just that desktops handle a lot more than individual commands, aiming to make it easier for the user to use the computer. I call it an "abstraction" because that's what it is. Instead of you writing commands manually into the terminal, you use a program that calls it for you and does the hard work. That's what an abstraction is, you're abstracting away something by making an interface around it. All interfaces, as a matter of fact, are abstractions.
