Free online courseLinux course: Beginner to Sysadmin

Course Description

Want the confidence to navigate Linux like a sysadmin, even if you are starting from zero? This free online course guides you from your first safe setup in a virtual machine to the day-to-day skills used in IT support, operations, DevOps, and junior system administration roles. You will learn how to work efficiently in a terminal, understand what is happening inside the system, and build habits that transfer to any Linux distribution.

You will begin by creating a Linux environment without replacing your current operating system, so you can practice freely while keeping your main computer intact. From there, you will develop command line fluency: moving through directories, creating and managing files, and using text editors comfortably. As your workflow grows, you will discover why shells are powerful tools, using pipes, redirection, filtering, and search techniques to turn raw output into clear answers.

Administration becomes real when you can maintain software and keep systems stable. You will practice package management with common Ubuntu-style tooling, understanding updates, installs, and the role of repositories. You will then move into the operating system core: what processes are, how to inspect them, how signals work, and how to interpret state and priority. You will also explore the /proc filesystem to connect command output to what the kernel is tracking under the hood, an essential perspective when troubleshooting performance and reliability issues.

To tie everything together, the course explains the Linux filesystem layout so you can locate configuration, binaries, and key system directories with purpose rather than guesswork. Finally, you will take a first step into automation with bash scripting. You will learn why scripts matter, how quoting and variables prevent mistakes, how scripts run, how to pass arguments, and how to make decisions with tests, functions, and reusable logic. By the end, you will have a solid foundation for real-world system work and a clear path to keep leveling up your Linux and automation skills.
