One question I get a lot: "Do I need to pay to learn Linux?" My answer: not necessarily, at least not to start. The Introduction to Linux course from the Linux Foundation itself is free, and it's offered by the very organization that defines Linux certification standards like LFCS.
This course covers everything from command-line basics to process management and Bash scripting — exactly what we work on hands-on in my own Linux Server Administration course.
