Linux tutorial

Ryan Chadwick, the author of this tutorial, enjoys teaching Linux to students. He’s been doing that for more than ten years. And one of the things he teaches is how to be lazy, but creatively — that is, how to assemble tools to do virtually anything, to have the computer do the work for its master.


After taking this tutorial, you probably won’t be a Linux guru, but you will have the right knowledge to get there if that’s what you want. The tutorial gives a foundation in how to use the terminal and how to use the Linux command line (Bash). Its purpose is to take the mystery, complexity, and scariness away from the command line. Also, the tutorial aims to explain the most suitable use cases for the command line and for the GUI.

Linux journey


An online, textual, and interactive journey throughout the realms of Linux. There is no predefined path on this journey. You can jump directly to the topics of your interest: command-line, permissions, processes, packages, file-systems, devices, networking, troubleshooting, etc. Or, if you prefer, you can follow the suggested order.

Either way, in this site, you will find plenty of resources and knowledge to master all the aspects of the Linux operating system. Every topic is explained in detail, with practical examples, and each lesson has a short exam to put your knowledge to the test.

The Linux basics course

A collection of 55 YouTube tutorial videos, ranging from basic Linux shell commands for beginners to OS virtualization, network security, and other specific topics for professional system administrators.

The author started making these videos for a friend who wanted to learn how to become a Linux sysadmin. The first videos were so successful that the author expanded the playlist to cover a wider range of topics, tools, practical projects, and career advice.

The videos seek a balance between theory and practice, trying to give the theory necessary to understand the system under the commands and, in turn, offer practice material to learn how to solve real-world problems.

linux certification

This is not a course for beginners, taking into account that it covers advanced topics, such as the Linux kernel specification, the boot process, and the loadable kernel modules. Throughout the lessons, you will practice techniques for configuring a Linux kernel from scratch and downloading and searching the Linux kernel source code.

Almost every chapter is followed by challenge videos that offer you to test your learned Linux skills.

The topics include reading Linux kernel messages, reading and writing files from the proc and sysfs filesystems, configuring GRUB, using kernel command-line parameters, debugging, configuring run levels, etc.

Learning options for all tastes

At this time, you should have a clear idea about how to start learning Linux administration, whether you prefer to read books, watch videos, attend classes, or read interactive web pages. If you are currently working in IT, or are planning to start a career in IT, you should pick one of these options, and start learning Linux administration right away.
