# The clean command

The clean command is used to delete the generated book and any other build
artifacts.

```bash
mdbook clean
```

#### Specify a directory

The `clean` command can take a directory as an argument to use as the book's
root instead of the current working directory.

```bash
mdbook clean path/to/book
```

#### --dest-dir

The `--dest-dir` (`-d`) option allows you to override the book's output
directory, which will be deleted by this command. If not specified it
will default to the value of the `build.build-dir` key in `book.toml`, or to
`./book` relative to the book's root directory.

```bash
mdbook clean --dest-dir=path/to/book
```

`path/to/book` could be absolute or relative.
