rm is not working and outputs mv: illegal option -- b

Question

I'm using Monterey and ohmyzsh in iterm2 and rm -rf (nor -Rf) is not working and outputs mv: illegal option -- b. What is a good cli way to do this?

Edit: I have used remove in the past to remove files on a MBP. I believe it implicitly calls mv to do the work under the hood. This has since stopped functioning since my last project I have worked on in the past few months. It may have to do with sudo permissions (I dunno), Monterey, or it may possibly have to do with oh-my-zsh. At this point I was just looking for direction to look for an answer to look towards.

Answer 1

After editing my original question I am coming back to post that command rm -rf file_to_delete works today. It would be nice to know where we could find documentation that explains this.
