Free online courseLinux command line tutorial

Course Description

Gain the confidence to work in Linux from the terminal, the way IT support teams, system administrators, and DevOps workflows do every day. This free online course is designed for beginners who want practical command line skills that translate directly to real tasks: moving through directories, managing files safely, checking system activity, and understanding what your commands are doing behind the scenes.

You will start by getting comfortable with the shell and core commands used constantly on Linux systems. As you practice, you will learn how to read and write files efficiently, redirect input and output, search through text, and inspect results without getting lost. Along the way, you will also develop habits that prevent common mistakes, such as handling folders with spaces, choosing the right flags, and understanding when elevated permissions are appropriate.

The course also builds a strong foundation in permissions and ownership, so you can diagnose access problems and apply the right changes with confidence. You will see how Linux permissions behave for files and directories, how symbolic and octal modes differ, and how permission choices affect day-to-day work in shared environments.

As you advance, you will move from single commands to automation with Bash scripting. You will learn how scripts are structured, how to use variables and user input, pass arguments, work with conditions and loops, and organize reusable functions. You will also get exposure to debugging techniques and safe scripting practices, helping you create scripts that are easier to maintain and troubleshoot.

To connect your skills to real environments, the course includes practical system tasks such as monitoring processes and resources, managing users and groups, installing software, working with archives, using networking tools, and transferring files securely. You will also explore typical setup scenarios in virtual machines and common Linux distributions, making it easier to practice on your own computer and apply what you learn in support tickets, labs, or entry-level roles.
