ATC+
Linux
This learning series takes you from your first shell command to running Linux systems in production. Each path pairs short videos with hands-on labs on real machines, so you practice every skill on a live system rather than just reading about it. Start with the fundamentals: the filesystem, permissions, users, processes and package management. Then move on to scripting, networking, systemd, performance troubleshooting, storage and security. Take the paths in order, or start at the level that matches what you already know.
Linux Intermediate
Go beyond the basics: build robust shell automation, troubleshoot networks methodically, shape services with systemd, and manage storage and SELinux on real production Linux systems.
Linux Foundations
This learning path takes you from Linux fundamentals to confident system administration. You'll learn how Linux is structured, master the command line, and manage users, permissions, processes, and storage. You'll also harden systems against attacks and automate routine work with shell scripts, building the core skills every entry-level engineer needs to run Linux systems.
