I use the command line every day and still forget command options that I've typed a hundred times.
You know the ones: find syntax, the difference between -exec and xargs — gone the moment I need them.
So I built getchowned: three quick questions a day to keep the muscle memory alive.
Recall — name the command for a task
Build — assemble one from a prompt
Read — explain what a given command does
New questions daily, streaks to keep you honest, free, no signup.
I'd love feedback from this crowd on two things:
Difficulty — too easy, too obscure, about right?
Coverage — which commands or flags are worth adding? I want the stuff people actually forget, not trivia.
