--no-warn-ignored does not work?

[zpinto123]

Hey guys,

I currently have eslint working normal, but if I try and use the new --no-warn-ignored argument, I'll get this error:
Invalid option '--warn-ignored' - perhaps you meant '--ignore'?

Tried all these 3 different commands, but they all give the same error.

npx eslint --no-warn-ignored
npx eslint --max-warnings 0 --no-warn-ignored
npx [email protected] --max-warnings 0 --no-warn-ignored

My eslint is version 8.56.0.
Even when running the 8.51.0 version, I get this error (version where --no-warn-ignored was introduced).

Hi @zpinto123!

Are you using eslint.config.js (the new flat config format), or .eslintrc config files? This CLI option is available only when using eslint.config.js config files.

Hmm, that must be the issue then.
I'm now trying to convert to eslint.config.js, but I noticed that it no longer supports a few of the properties that I have, like "env", "extends", etc.
Is there somewhere I can check on what to do about these properties that are no longer supported?
