Has anyone already taken this course or know specifically what it covers?
Check the link above
The course description seemed vague to me that's why I asked if anyone knew specifics. "This course explores the various tools and techniques commonly used by Linux programmers, system administrators and end users to achieve their day-to-day work in a Linux environment." Various tools and techniques could be bash, sed, awk or it could be anything else in the vast capabilities of a linux system.
