Linux Fundamentals
BeginnerLearn Linux from zero — the operating system behind most of the internet, the cloud, and developer machines everywhere. Get comfortable in the terminal, navigate the filesystem with confidence, and run the essential commands every engineer uses daily. Understand files and permissions (who can read, write, and execute), watch and control running processes, and install software with package managers like apt and dnf. No prior command-line experience required — by the end you can move around a Linux system, manage files and users, and feel at home on any server.
