`ruff format {{path/to/file_or_directory1 path/to/file_or_directory2 ...}}`

- Print which files would have been modified and return a non-zero exit code if there are files to reformat, and zero otherwise:

`ruff format --check`

- Print what changes would be made without modifying the files:

`ruff format --diff`
