And you too, thank you!

Okay, thank you for the resources then. Much appreciated!

Hi guys, first post on this discussion forum ever. Nice to meet you all. Hope this belongs here. I have just returned to college for IT after a lapse in enrollment. We're going to be working with Linux more in the future, and even the Powershell in Windows too. I have been messing around with the Raspberry Pi I got for one of my classes, but I pretty much have to Google every command I use in the terminal for it since I'm not that familiar with Debian (sorry, Raspbian), the Powershell, or Linux terminals at all. My question is this: what are some essential, need to know commands for moving around in and using the Powershell? You can give me one or several, list form, add a short description of what it does, whatever. I'll be jotting them all down in my notes with some extra fluff anyways for future reference. Appreciate it guys, thanks. TL;DR: Need useful, necessary Powershell / Linux terminal commands.
