Master Linux in minutes a day. Swipe through bite-sized True/False cards built from official GNU docs. Used by DevOps pros & sysadmins worldwide.

Stop forgetting the commands you looked up yesterday.

SwipeDrill: CLI is the fastest way to build real command-line fluency, one swipe at a time. Built from official GNU documentation, every card targets a single concept and drills it until it sticks. No lectures. No videos. Just you, a statement, and a swipe.

HOW IT WORKS

Each card shows a statement about a Linux command, option, or behavior. Swipe right if it's true. Swipe left if it's false. Get instant feedback and a clear explanation so you understand the why, not just the answer.
