Basic knowledge of Linux, including installing Linux and using the command line is helpful, but not required. If you don’t have any Linux experience, we highly recommend the free Introduction to Linux course on edX.
Lab Info
Lab exercises in this course are designed to work either on native hardware, or using a virtual machine (VM), under a hypervisor, such as those in the KVM, VMWare, or Virtual Box families. Detailed instructions to set up your lab environment are provided in the course.

This course was very challenging for me. As a lifetime Windows user using the GUI, I was weak in the command line, so this course was just what I needed.
Jun 2021
The course covers a wide range of topics, and the instructor is very knowledgeable.
May 2021
System and subsystems are very well explained. The course is very well made, and so are the videos. Good job!
Apr 2021
Some information covered in depth was very useful for me as a software developer, this was glossed over or missing in books I had read.
Apr 2021
The course provided information that is relevant to Linux today, with additional information on upcoming functions. The labs provided excellent examples for each section, and a good starting point for additional practice.
Apr 2021
The course support was fantastic! Any question I had was quickly answered by Coop (who I didn't even realize was the instructor at first, he gave quick friendly responses to questions) or Luis. Definitely a 5 star course.
Apr 2021
The course is very thorough in covering areas of Linux systems administration that are often overlooked/not thought of. The file systems overview was great.
Jan 2021
It is the first time I have a general introduction to the Linux OS, and I feel more confident after the course.
Jan 2021
It covers all that is needed for the exam, and gives an additional level of Linux administration that other Linux courses don't.
Jan 2021
The things I learn here are not easily found online. The learning path carved contains well structured contents that allows one to properly administer and use a Linux system. Fundamentals of why a technology is used is also explained, which is always the key part of rooting any new knowledge in a beginner.
Dec 2020
Vendor neutrality, covers more than one distribution where possible. Clear and concise explanations of features and commands, plus the reasons *why* they would be used.
Sep 2020
I loved the labs. Any chance to actually put what I am learning to use is very helpful. Sometimes I think I am understanding a subject, but when I get to a lab I realize I have to try to understand it more. In addition, it allows me to say, yes I get that now.
Sep 2020
I like how modular it is, that I can pop in, run through a chapter rather quickly, and then pop out. I also like that the labs are downloadable pdfs, as I sometimes take the course on a Windows laptop with a Linux VM, and other times log in on a Linux PC.
Aug 2020
There was a lot of depth in the course content, with practical examples. Most of the subject areas were explained clearly. The online support was prompt and helpful.
Aug 2021
Although I found out that using a Linux operating system is not easy, this course has many parts that are easy to practice, and has provided all the instructions necessary to handle many situations.
Aug 2020
I liked that each chapter was short, so I could commit to doing one at a time. I enjoyed the quizzes as a knowledge check and motivational reward for finishing each section. I love the UI improvements that just came out (I used the platform before and after and I enjoyed the improvement!)
Aug 2020
The content is up-to-date. There are practical examples that are useful for everyday duties. The labs are great. The setup script for the course was very useful. It is vendor neutral.
Jul 2020
For someone planning on becoming a Linux administrator I feel they will need more details, and Linux is not intuitive to learn, meaning you need a lot of guidance to find your way around, and this course certainly helps. The exercises at the end of each chapter were useful, and I saved a lot for future reference. I'm only a casual Linux user, and the content was useful.
Jul 2020
No stone left unturned. The demo videos really helped for a big picture perspective, and brought abstract concepts to life. I also enjoyed that I could review anything I missed at the end of chapter quizzes.
May 2020
I thought that the order in which things were presented was conducive to getting things well sorted and into long term memory.
May 2020
Focus on practical scenarios over raw theory with real-life examples.
May 2020
The course was very well planned with sequential learning goals.
Feb 2020
I liked that it opens your mind to possibilities, each chapter was well designed to of course give the introduction to each specific topic. After taking this course I discovered Linux is huge, and being able to create a course I believe was a bit of a challenge, but in the end I recognize and congratulate all people involved in creating it to spread the knowledge and continue to contribute to the open source community.
