This is some good advice. I’d add two caveats though: - For learning the distro’s package manager, while I’d say it’s definitely good to learn it (and do so early on), I’d also say beginners should probably stay away from the command line version of it unless it’s absolutely needed. - For running commands from random websites rather than a blanket prohibition, I’d say don’t do it unless you can confidently say you understand what the command will do and are willing to take the risk that you’re wrong.
