# Dotenv Linter

> CodeRabbit's guide to Dotenv Linter.

[Dotenv Linter](https://github.com/dotenv-linter/dotenv-linter) is a lightning-fast linter for `.env` files. It helps ensure your environment files are consistent, typo-free, and follow best practices.

## Files

Dotenv Linter will run on files with the following patterns:

* `**/.env`
* `**/.env.*`

We will not run against files that do not start with `.env` (e.g., `test.env`). However `.env.dev` or `.env.local` is fine.

<Note>
  Dotenv Linter does not require configuration to run and automatically anlysises `.env` files. If no configuration file is found, it will use default settings.
</Note>

## When we skip dotenv-linter

CodeRabbit will skip running dotenv-linter when:

* No `.env` files are found in the pull request.
* dotenv-linter is already running in GitHub workflows.

## Notes

* All dotenv-linter issues are treated as warnings (dotenv-linter does not distinguish severity levels).

## Features

Dotenv Linter can detect:

* Key duplication
* Missing values
* Incorrect formatting
* Invalid characters
* And many more issues
