It’s more common than you think. I graduated in 2013 and can tell you there were minimal opportunities to learn how to operate a Linux command line (if you didn’t already want to). Most jobs will set you up with some IDE with the codebase preloaded and a big green compile button, it’s just easy to avoid I guess.
I’ve been using Linux since 2008 and it’s the most high-yield skill set I have, it makes everything simpler and I encourage others to learn it.
