What parser are you using?

Default (Espree)

What did you do?

> mkdir eslint-bug
> cd eslint-bug
> npm init
> npm i eslint
> touch .gitignore
> eslint --ignore-path .gitignore # succeeds
> touch eslint.config.js
> eslint --ignore-path .gitignore
Invalid option '--ignore-path' - perhaps you meant '--ignore-pattern'?

What did you expect to happen?

--ignore-path works in any case. Is --ignore-path intentionally not supported when using eslint.config.js? If so then the docs for --ignore-path need to make this clear.

What actually happened?

When eslint.config.js exists, running eslint --ignore-path .gitignore errors out: Invalid option '--ignore-path' - perhaps you meant '--ignore-pattern'

The option disappears from eslint -h as well.
