I built a daily Linux command-line quiz because I kept forgetting flags

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.
