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.

I was a scholarship winner of this course and the LFCS exam. I thought the course was great. I thought I knew about Linux administration but there were entire sections I didn't know about or didn't really understand like RAID, LVM, encryption, quotas, etc. I finished the course and felt accomplished.
Sep 2021
It covers lots of important topics. Really appreciated the advice and tips on System Security matters.
Sep 2021
I've been using Linux as a hobbyist for a little over 20 years, but I still learned a lot. And I now understand what certain technologies like PAM and SELinux are for, even if I'm fuzzy on how to use them.
Sep 2021
I've always struggled with sed/awk and the if/then & if/of statements, but after this course, I have a much better comprehension of how these commands work, and how to formulate them.
Jul 2021
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 learnt 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.
