# Unified commands

Unified commands are a fixed set of commands that are available in every shell, and are usually not tied to any specific function or component of an application. For example, unified commands like `exit`, `fork`, `alias`, and `presets` provide useful functions and scripting commands to make your shells more flexible and usable.

{% hint style="info" %}
Most of the unified commands are hidden, and you can show them using the `-hidden` switch in the help command. You can learn more about hidden commands [here](https://aptivi.gitbook.io/stable/terminaux-8.0-manual/usage/input-reader/shells/shell-structure/..#command-flags).
