I passed the Linux Essentials exam

May 21, 2017

The LPI Linux Essentials certification demonstrates fundamental knowledge of the open-source industry, an understanding of the major components of the Linux operating system, and technical proficiency in the command line.

I had fun studying for this certification. I picked up the majority of my Linux skills in a piecemeal way through occasional projects over the years, so it was nice to sit down and learn the basics in a logical, progressive manner. Many concepts rattling around in my head gelled in satisfying ways.

How I studied

The bulk of my learning took place through LinuxAcademy.com’s Linux Essentials course. The course contains 14 hours of video lectures and several practice tests. I found the course to be well-structured and the instructor’s presentation clear, and concise.

My methodology was watching the lectures in order and taking notes. For lessons involving the command line, I created a CentOS 7 virtual machine on my workstation and followed along with the video, typing commands. I also studied a few of the flash-card sets contributed by LinuxAcademy users. These cards were useful in memorizing relevant commands.

For more depth, I read through sections of LPIC-1 Linux Professional Institute Certification Study Guide—though it’s not necessary to read this book to pass the exam.

Mistakes I made

I should have spent more time studying popular applications for desktop Linux distributions. I saw at least 2 questions on this topic and I’m fairly certain I got both of the questions wrong.

There was also a question about selecting which distros use the RPM package manager. I didn’t remember one of them (Mandriva).

Yet another mistake I made involved the mv command. The question was along the lines of, “You want to move /dirA and all of its contents to /dirB. Which is the correct command?” I had the correct answer narrowed down to two options, essentially:

mv /dirA /dirB


mv -R /dirA dirB

I chose the command with the -R option, which is wrong. There is no -R option available with mv.

Where to go from here

The next exam on this path is the LPIC certification exam, but I think RHCSA would be more beneficial to my career.
