Agree. Proficiency with the command line and basic navigation and common tools, ssh, git and Github, at least one professional editor or IDE for each platform (e.g. VSCode and vim or nano) seem like table stakes for a professional developer. Bonus for screen/tmux, fuzzy finding, reading shell scripts, environment variables. Not everyone has to use all of these things, depends on the environment. Then again I've had to work with "front-end developers" and even so-called "full-stack" developers who don't know HTML, CSS, and Javascript.
