Linux lab
The command line, hands-on. Learn mode covers files, permissions, processes and text handling; Break-fix mode puts you on a genuinely broken machine and asks you to fix it at the shell.
Why this matters: Every layer above this — containers, clusters, GPU nodes, CI runners — is a Linux box underneath. Time spent here pays back in every other area on this site, and it is the practical half of the LFCS.
