I will open a PR for this to mimic sshcode's version flag.

@nhooyr I am assuming that I should add docs for it, right?

[nhooyr]

I don't think docs are necessary. Its an expected feature of all commands.

[teddy-codes]

lol ok, I wrote them anyway... should I remove them? 😢

[nhooyr]

lmao, sorry about that. its best the docs remain lean.

[teddy-codes]

Ok, no worries. will remove them. I am waiting for my other PR to get approved (I thought that I was only contributing one thing), then I'll rebase and open a PR for this as it's already done.

[nhooyr]

You can just create a new branch and open another PR.

I branched off my master, so it contains things for the other PR. I think that would be messy 👀
