Webpack-cli: bug: version flag doesn't care about other arguments

[snitin315]

Describe the bug

version flag doesn't care about other arguments supplied at the same time.

What is the current behavior?

To Reproduce
Steps to reproduce the behavior:

webpack --version --abc

Expected behavior

Should throw a warning fo invalid args.

Please paste the results of webpack-cli info here, and mention other relevant information

Additional context

Looking into it. Open for discussion

Should output an error like do other cli (exit code - 2), for example eslint do:

Invalid option '--abc'.

[snitin315]

Sounds good. I will work on it.

Same is the case with --help flag, take on both of them together.

[anshumanv]

What happens in case of multiple commands? Which takes precedence?

[snitin315]

@anshumanv Can you provide some examples?

[anshumanv]

webpack-cli version init or webpack-cli init version

[snitin315]

It should output the version of init as well. #1363

[anshumanv]

Yep that would be good 👍

I think json flag also doesn't care about any other flag
