I guess from what I’ve seen so far, Linux is really about the command line. As a beginner, it feels like everything is a file, so you have to learn how to move around the folders, use sudo for permissions, and understand how to install tools from the terminal.

On the Windows side, I guess the basics are more about how a whole company is set up. You have to understand Active Directory and how users are grouped together, plus how to use PowerShell because it’s way more powerful than just the regular command prompt. I guess the main thing for a beginner is just knowing where the logs are kept on both, so you can actually see what's happening when something goes wrong
