Shell Starter · Support
Scripts run in the bundled mvdan/sh Go/Wasm interpreter. This is a POSIX teaching subset, not a system shell or full Bash environment. There is no SSH, arbitrary system command execution or network access from scripts. Input, output, file size and execution time are limited.
One editable default workspace and all 20 lessons are free. IDE Pro is an optional one-time purchase for multiple local projects and duplication. The default workspace cannot be deleted. Restore purchases with the same Apple Account. Family Sharing is not enabled.
Scripts can read source files and UTF-8 project data inside a virtual workspace. Successful runs write generated files to the project data folder. Failed, stopped or timed-out runs do not commit their file changes. Back up your projects; the app provides no cloud sync or backup.
If a command is unavailable, consult the in-app reference. Use Console to provide input, send EOF or stop a script. For support, email ministep@dozen.network with your app version, device, OS and reproduction steps. Remove passwords and unrelated personal data.
