### eslint.format(formatter, output)

Format all linted files once. This should be used in the stream after piping through `eslint`; otherwise, this will find no ESLint results to format.

The `formatter` argument may be a `String`, `Function`, or `undefined`. As a `String`, a formatter module by that name or path will be resolved as a module, relative to `process.cwd()`, or as one of the [ESLint-provided formatters](https://github.com/eslint/eslint/tree/master/lib/formatters). If `undefined`, the ESLint “stylish” formatter will be resolved. A `Function` will be called with an `Array` of file linting results to format.
