Build command-line confidence, one useful session at a time.
Terminal Drill is an offline practice companion for terminal skills, developer workflows and Linux administration. Learn with short lessons, recall commands, troubleshoot simulated machines and take the same tasks to your own system.
FOUR LEARNING TRACKS
• Terminal Foundations — files, text, permissions and everyday shell skills.
• Developer Workflows — Git, shell productivity and automation.
• Linux Operations — services, networking, storage and containers.
• RHCSA preparation — a RHEL 10 curriculum with 83 lessons, review assignments, 48 chapter labs and six capstones.
PRACTISE, THEN APPLY
Choose guided practice or independent recall. Use hints when you need them, then return for a later retrieval attempt. Practical labs check the represented machine state, including protected data and configuration that must survive a simulated reboot. Each lab declares its supported commands and limitations. Companion guides help you practise on a disposable real system.
The 66 practical labs include twelve additional exercises across shell reasoning, Git recovery, files and text, service troubleshooting, networking and container operations. Labs are bounded teaching simulations, not a Linux runtime. They remain labelled as awaiting independent technical review; completion is not a certification or an exam-readiness guarantee.
CLASSIC OR ADVENTURE
Keep the familiar Classic experience, or switch to Adventure in Settings. Adventure adds missions, a character profile, twelve achievements, earned titles and cosmetics, flexible weekly goals and a collectible homelab. Progress, XP and purchases are shared between modes. Switch whenever you like.
