    Usage: stylelint [input] [options]

    Input: Files(s), glob(s), or nothing to use stdin.

      If an input argument is wrapped in quotation marks, it will be passed to
      globby for cross-platform glob support. node_modules are always ignored.
      You can also pass no input and use stdin, instead.

    Options:

      --config

        Path to a specific configuration file (JSON, YAML, or CommonJS), or the
        name of a module in node_modules that points to one. If no --config
        argument is provided, stylelint will search for configuration files in
        the following places, in this order:
          - a stylelint property in package.json
          - a .stylelintrc file (with or without filename extension:
            .json, .yaml, .yml, and .js are available)
          - a stylelint.config.js file exporting a JS object
        The search will begin in the working directory and move up the directory
        tree until a configuration file is found.

      --config-basedir

        An absolute path to the directory that relative paths defining "extends"
        and "plugins" are *relative to*. Only necessary if these values are
        relative paths.

      --print-config

        Print the configuration for the given path.

      --ignore-path, -i

        Path to a file containing patterns that describe files to ignore. The
        path can be absolute or relative to process.cwd(). By default, stylelint
        looks for .stylelintignore in process.cwd().

      --ignore-pattern, --ip

        Pattern of files to ignore (in addition to those in .stylelintignore)

      --syntax, -s

        Specify a syntax. Options: "css", "css-in-js", "html", "less",
        "markdown", "sass", "scss", "sugarss". If you do not specify a syntax,
        syntaxes will be automatically inferred by the file extensions
        and file content.

      --fix

        Automatically fix violations of certain rules.

      --custom-syntax

        Module name or path to a JS file exporting a PostCSS-compatible syntax.

      --stdin

        Accept stdin input even if it is empty.

      --stdin-filename

        A filename to assign stdin input.

      --ignore-disables, --id

        Ignore styleline-disable comments.

      --disable-default-ignores, --di

        Allow linting of node_modules.

      --cache                       [default: false]

        Store the info about processed files in order to only operate on the
        changed ones the next time you run stylelint. By default, the cache
        is stored in "./.stylelintcache". To adjust this, use --cache-location.

      --cache-location              [default: '.stylelintcache']

        Path to a file or directory to be used for the cache location.
        Default is "./.stylelintcache". If a directory is specified, a cache
        file will be created inside the specified folder, with a name derived
        from a hash of the current working directory.

        If the directory for the cache does not exist, make sure you add a trailing "/"
        on *nix systems or "\\" on Windows. Otherwise the path will be assumed to be a file.

      --formatter, -f               [default: "string"]

        The output formatter: ${getFormatterOptionsText({ useOr: true })}.

      --custom-formatter

        Path to a JS file exporting a custom formatting function.

      --quiet, -q

        Only register violations for rules with an "error"-level severity (ignore
        "warning"-level).

      --color
      --no-color

        Force enabling/disabling of color.

      --report-needless-disables, --rd

        Also report errors for stylelint-disable comments that are not blocking a lint warning.
        The process will exit with code ${EXIT_CODE_ERROR} if needless disables are found.

      --report-invalid-scope-disables, --risd

        Report stylelint-disable comments that used for rules that don't exist within the configuration object.
        The process will exit with code ${EXIT_CODE_ERROR} if invalid scope disables are found.

      --report-descriptionless-disables, --rdd

        Report stylelint-disable comments without a description.
        The process will exit with code ${EXIT_CODE_ERROR} if descriptionless disables are found.

      --max-warnings, --mw

        Number of warnings above which the process will exit with code ${EXIT_CODE_ERROR}.
        Useful when setting "defaultSeverity" to "warning" and expecting the
        process to fail on warnings (e.g. CI build).

      --output-file, -o

        Path of file to write report.

      --version, -v

        Show the currently installed version of stylelint.

      --allow-empty-input, --aei

        When glob pattern matches no files, the process will exit without throwing an error.
