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.

I'm sure someone will correct me but I believe 90% of professional Linux is done at a commandline, DEs are mostly for personal use
It's a useful skill to have for a number of different jobs but usually not the primary one as most techies have some working Linux knowledge anyway
Developers, pentesters, system architects and similar
Did Linux sys admin type work for a few years and can confirm there was never a DE in sight
I did nearly a decade. DE's (or just wms) on devs' desktops and obviously ssh or console shells on server and network hw. Devs may or may not take care of their own software, though.
Also network protocols, sniffers, support, hardware, security... It tends to expand and admins are the goto for tech questions. So it's kind of a know everything about everything job. And a very thankless one, since if you do your work right, nobody will even notice what's going on since everything just works.
I worked in a small team and our stuff rarely broke. We set it all up to use minimal resources and mostly automated maintenance and we went unnoticed for most of my time there. Everyone else thought we were just sitting around doing nothing and getting paid for it. It created an uncomfortable environment, was glad to leave at the end of it.
I have to hope most devs using Linux would be able to manage their own machines no?
Unless they are not allowed to of course
I think the internet can inflate this view. In my experience supporting devs, there are many very smart people in their wheelhouse who are not very good at system administration. I think it is much like academics who are also often assumed to be good at computers, rather than good at what they do on computers.
Not really... Many are just devs used to say Windows who happened to get to work in a linux environment.
