What does “command line interface” mean?
command line interface
Oh okay, this is a techy one but super useful to know!
A "command line interface" (people often just say "CLI") is a way to talk to a computer by typing text commands instead of clicking on pictures or buttons.
So imagine your computer screen is just black with a little blinking cursor. You type something like "open this folder" or "delete this file" — but in special computer language — and the computer does it. For example, a programmer might type a command to run their code, and the computer just… runs it. No clicking, no menus.
It's the opposite of a normal desktop where you drag and drop things with your mouse.
Basically, a command line interface is a text-only way to control your computer by typing instructions directly to it.
