I passed the Linux Essentials exam
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
bash>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
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.
