While "most *nix folks over a certain age already know it well", IMO it would be a shame for it to limited to them. I regularly encounter younger developers unfamiliar with standard tools like sed, tr, cut, etc. that I use often to solve everyday personal tasks. The world took a wrong path when *nix tools were no longer seen as appropriate things for ordinary people to learn. (Yes, in the 1980s clerical staff in some companies were taught awk or even Emacs.) Productivity of the labour force would only rise. When my spouse moved to my country and didn’t yet know the local language, she worked for a multinational outsourcing firm. The job turned out to be little more than glorified data entry and it could have been easily automated with *nix tools piped. Hiring educated people to sit 8 hours a day and do everything manually was a waste of money and human potential.
