Learn Linux Commands Offline

Learn the Linux command line by typing real commands into a safe, simulated terminal. Nothing can break, nothing needs root, and it all works offline. A SAFE TERMINAL IN YOUR POCKET • Simulated bash shell with its own files and folders • Navigate, create, copy, move and delete files, then reset with one tap • Pipes and redirection (|, >, >>), grep, cut, sort, find, tar, chmod and much more • A symbol toolbar above the keyboard for | > ~ / - * . && and other characters that are hard to type on a phone 40 LESSONS FROM ZERO Short, practical lessons in 8 units, from your first ls to permissions, processes, archives and text processing. Each lesson ends with commands you try yourself. 120 HANDS-ON CHALLENGES Story-based tasks across 12 levels: clean up a log folder, fix permissions, find a config file, extract an archive. The app checks the real result in the terminal, not just the command you typed.
