# ShellCheck

> ShellCheck is a static analysis tool designed to identify and report syntax errors and potential issues in shell scripts

You can enable the ShellCheck linter with:

## Auto Enabling

ShellCheck will be auto-enabled if any *Shell* files are present.

## Settings

ShellCheck supports the following config files:

* `.shellcheckrc`
* `shellcheckrc`

You can move these files to `.trunk/configs` and `trunk check` will still find them. See [Moving Linters](../configure-linters#moving-linters) for more info. Trunk Code Quality provides a default `.shellcheckrc` if your project does not already have one.
