Many [empty] questions and answers in Linux Essentials. If you need help fixing this course, I can help. I am a Linux systems / cloud engineer and configure, use, maintain, support, and troubleshoot Linux. I have extensive BASH and GNU Linux experience. Currently using Arch/Manjaro. I also have experience with Python, Javascript, TDD/BDD, Agile, Docker, OpenStack.
I teach A+, Network+, and Cisco Learning Services IT course. I have created content for A+, and Network, and currently working on fixing improving some Cisco courses.
Even if you don’t use my expertise, please fix this course. Linux is the most important OS for someone new to systems admin to learn. These issues are present in Android version as well (tested). I assume it the same in iOS since what is missing is content!
