Real shell muscle memory.
Three minutes a day.
Terminal Drill is a focused practice app for Linux and shell fluency. Short, hand-typed drills. A matcher that understands flag order and synonyms. Zero data collection.
Built like a typing trainer, tuned for the shell.
Not a flashcard app. Not a quiz game. Real commands, hand-typed, with feedback that respects how shells actually work.
Six drill formats
Type-the-command, multiple choice, scenario, fill-blank, fix-the-broken-command, explain-the-output. The same engine, different surfaces.
A matcher that thinks
Understands flag order, common synonyms, and near-misses. Type w when the canonical answer is who and the app explains both.
Easy & Regular modes
Easy shows the target command for type-along practice. Regular asks for recall from prompt only. Switch any time.
Streaks & mastery
XP, levels, badges, per-module mastery, fastest-category, weakest-category — and a daily challenge that's the same 10 drills for everyone, every day.
The Codex
Every command searchable, with one-line summary, when-to-use bullets, flag table, examples, common mistakes, and a "Practice this" button.
Zero data, zero network
No accounts, no analytics, no servers. Everything stays on your device. The app makes literally no network calls.
A real drill, in your browser.
Same engine as the app, scaled down to a single card. Type the command, hit ↵, see what the matcher thinks.
Every screen, hand-crafted.
The actual app — Today, Drill, Path, Profile, the works.

How smart is the answer matcher?
ls -la vs ls -al), common synonyms (vim vs vi), and near-misses. When you're close but not exact, it shows what was accepted and what the canonical answer was. It's strict where strictness matters and lenient where typing matters.
