Learning Linux and Linux careers
I'm new. I know very little about Linux but I'm actually here to ask some questions for a friend. She's seeking a dramatic career change and wants to start learning Linux (she has no programming experience). She abandoned Windows during the dark ages of IE6 and has been using Linux since. Originally just for the sake of having a functional OS she's now interested in potentially going more into Linux and I'm trying to do research to understand what career opportunities are out there, Linux related.
I'm a front-end developer myself (html, css, js, etc). As far as I can tell Linux is often dealt with in terms of server management. Can anyone shed some more light on the subject? Thanks in advance.
