    ruff check path/to/code/            # Lint all files in `/path/to/code` (and any subdirectories).
    ruff check path/to/code/*.py        # Lint all `.py` files in `/path/to/code`.
    ruff check path/to/code/to/file.py  # Lint `file.py`.
    ruff check @arguments.txt           # Lint using an input file, treating its contents as newline-delimited command-line arguments.

To run Ruff as a formatter::

    ruff format                          # Format all files in the current directory (and any subdirectories).

    ruff format path/to/code/*.py        # Format all `.py` files in `/path/to/code`.
    ruff format path/to/code/to/file.py  # Format `file.py`.
