[BUG] npm ls --omit=dev does not omit dev dependencies

[denik1981]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

npm ls --help does not show --prod between the list of options available this command accepts.
It forces me google for it to remember it and --omit dev still lists both prod and dev dependencies together so this might be the source of a different issue

Expected Behavior

Should list --prod among the list of options

Steps To Reproduce

1. npm ls --help
2. See --prod is missing

Environment

• npm: 8.5.5
• Node.js: v14.19.0
• OS Name: ubuntu 20.04.1

hmm, i'd expect --only=prod to be the preferred alias, but that one's not listed either, only omit is.

only is deprecated, which I think is why its not listed for ls (or any other commands). https://docs.npmjs.com/cli/v8/using-npm/config#only

This definitely seems like a bug. The docs explicitly call out: When set to prod or production, this is an alias for --omit=dev. Here's the output that from the cli itself, which directly contradicts that:

❯ npm ls --only prod | grep tap-snapshots/

❯ npm ls --omit dev | grep tap-snapshots/

Yes, well I suppose the correct usage is with --omit dev as you say if it happens that --prod is deprecated.
Thanks for addressing this issue.
