What is the command line? An introduction to the interface at the heart of Linux & Unix systems.
Here’s part the second of our ongoing introduction to Linux computing, What is the Command Line?
OK now you have a Linux computer, and you are ready to make it do your bidding! We’re going to cover how to send commands to your Linux machine using the command line – you know, a line where you send commands!
In order to start typing those commands (list files! print this one out! open the web browser!) you will use a shell – a shell is a little like the Finder on Macs, or the desktop Explorer on windows but is not graphical – it uses only TEXT.
A shell is a program with a command-line interface which you talk to with a terminal. Terminals are software or hardware that let you send text back and forth to a computer. Shells offer a very specific kind of command line, but what we mean in general by that term is an interface where a user types commands and the computer responds.
(If you missed part one, What is this “Linux”, anyhow?, you probably want to start there. And stay tuned – more to come shortly.)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
