Actually this reminds me, what is the deal with tar command recommendations to use or not use dash? I know GNU tar accepts both (e.g.) tar xvf file.tar and tar -xvf file.tar, but at some points people were like “NO! Don’t use the dash! It’s going to maybe cause issues somewhere, who knows!” and I was like “OK”. Something to do with people up designing the Unix specs?
