Crash course on Linux with DevOps in mind

I've been learning linux for a while now and I personally don't a basic crash course but an in-depth course for linux. But considering how much it has improved my knowledge of computers and improved my work flow. I think linux would be good topic and you can give a course for now and later if you plan to give a devops course, your linux course, git course and your english channel docker course would be a good pre requisite, if you plan to raise the bar for docker again. It will be good. I think linux would make perfect sense, language will should be audience opinion
