If folks want to look at some of the other oc mirror references, in this pull or follow-up work, here's the start of an audit:

But I don't see a reason to make a completely clean audit a prereq for incremental improvement:

I realized that there are more of oc mirror without the hyphen while reading further in the doc and found the nice summary in @wking 's comment. ❤️

If the associates in the docs team want to fix them with one shot, I am fine to close this pull.

@ all
This has come up a few times before. Our installation procedure installs oc-mirror as an oc CLI plugin. We can use oc-mirror as a binary and execute commands with hyphen but per discussion with all docs stakeholders we have decided to keep it aligned with the installation steps and use oc mirror without hyphens.

We can probably try adding a note in docs if this needs to be clarified.
