## What is Terminalogy?

Copied a terminal command from a tutorial, a colleague, or an AI tool and want to understand it before running it? Terminalogy is a local command dictionary that explains command structure, meaning, and potential effects.

Use Terminalogy to:
• Paste a complete command and read explanations of commands, options, arguments, paths, pipes, and redirections
• Search or browse 500 command entries with syntax, examples, common pitfalls, platform differences, and sources
• Understand risks involving deletion, overwriting, permissions, networks, or sensitive information
• Save useful entries and queries for later reading
• Read in English or Simplified Chinese

Command lookup and explanation happen on your device. The dictionary works offline. Terminalogy helps you understand commands; it never executes them or uploads your queries.

Dictionary entries, command explanations, risk guidance, and sources are free. An optional one-time purchase, Terminalogy Pro, adds semantic coloring and token interaction across Mac, iPhone, and iPad using the same Apple Account. No subscription.
