From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My employer paid for a course heavily based on it (No cert, but condensed and more useful), and for my time. One tutor and two pupils over a week.

I found it moderately interesting, and slightly useful. It was the most relevant training available for administrating our (then) CentOS 5/6/7 servers. There were bits that didn't transfer across to CentOS, mostly the proprietary RHEL software aspects which we largely skipped. There was much that was useful for any linux distro.

Highlight for me was properly learning awk during it - I still use that every day.
