I’m not sure how this fits into the usual flow of things with EE Bookshelf, but given all the interest in the Raspberry Pi, I figured there are probably a lot of people out there for whom this might be their first foray in Linux. While there are a lot of good books and resources out there for Linux, it can be tough to wrap your head around which commands are available from the console, etc. The GNU Coreutils documentation does a decent job of showing what should be included in any distribution, and will hopefully help people get a bit more familiar with the command line. There’s also a PDF version for offline browsing.
If you’re just looking for a concise cheatsheet, there’s lots out there, but this one from FOSSWire should get you started pretty quickly.

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.
