# I built a daily Linux command-line quiz because I kept forgetting flags > Source: > Published: 2026-06-27 21:19:56+00:00 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.
