iLinux is a shell command reference and learning app for developers, operators, and terminal enthusiasts. It covers Linux, Windows CMD Batch, and PowerShell. Fully offline, no ads, no tracking. Carry a complete command handbook in your pocket.

Core Features

Command Library

1. 1650+ offline entries: 1050+ Linux CLIs, 300 CMD Batch commands, and 300 PowerShell cmdlets.

2. Linux uses 14 categories; CMD and PowerShell each have their own layout for clearer cross-platform study.

3. Every command includes a concise summary and a Markdown article with syntax, flags, examples, and notes.

Cross-Platform Equivalents

Whether you are new to Linux, a terminal power user, a developer comparing Windows and Linux commands, or an operator who needs a pocket reference on iPhone and iPad, iLinux is your shell command dictionary on the go. Built to teach and reference commands, not to emulate a terminal. Feedback and App Store ratings are welcome.
