Linux Fundamentals
Permissions, processes, filesystems, packages and logs — worked through as ten short quizzes. These are the questions that come up in a screening round for any backend, SRE, DevOps or support role, and the ones that get skipped because nobody sits down and revises them.
Who it is for: Engineers with a Linux box in their day job who have never had to explain it out loud, and candidates with a screening round coming up.
