For example 10 or 25 question mode. After finishing you get a summary and stats. then you can repeat the same set to compare or reshuffle for fresh tasks </p> <h2> final words </h2> <p>I am building this as a cozy project for myself but maybe it is useful for others learning or refreshing linux commands.<br><br> If you try it out let me know what you think. Ideas for new tasks are always welcome ✌️</p> <p>I also wrote a bit more about this update on my personal blog -&gt; <a href="https://www.codephilip.com/notes/2025-09-22-cozycli-v02" rel="noopener noreferrer">codephilip.com/cozycli-v02</a></p> <p>and made a small devlog on my youtube channel<br> <a href="https://www.youtube.com/watch?v=_DFBjMtCHmc" rel="noopener noreferrer">cozyCLI v0.2 - 150 Tasks, Stats and Cheatsheet</a></p> showdev webdev cli linux
