The proof product for Drill Atlas.
TerminalDrill shows that the recall loop works as a real app: content packs, daily challenges, local progress, review, command reference, and privacy-first product behavior.
Local progress
Progress stays on device. The app does not need app-owned telemetry to make the practice loop useful.
No real execution
TerminalDrill never runs shell commands. It trains recognition, typing, explanation, and safe command shape.
All 18 modules.
TerminalDrill covers the full range of Linux and shell command fluency, organised by domain.

Feature breakdown.
What you get with TerminalDrill, from daily practice to deep reference.
Daily challenges
A fresh set of drills every day, covering different modules to keep recall sharp across the full command spectrum.
Module-based learning
18 focused modules let you drill specific domains — from navigation to troubleshooting — without noise from unrelated topics.
Safety notes
Every drill includes a safety note that flags real-world edge cases, destructive flags, and common mistakes.
Command reference
Built-in reference for all 207 commands with common flags, usage patterns, and related command suggestions.
Review mode
Revisit past drills, review incorrect answers, and track improvement over time without starting from scratch.
Privacy-first
All progress stays on device. No account required, no telemetry, no data collection. The app works fully offline.
A look inside.
Two everyday TerminalDrill screens: the daily workout and a drill session.
Find files by name.
find . -name "*.log"
TerminalDrill drills short command shapes before they are needed in a noisy terminal session.
