Yes, I just looked at the less-than-useless manual page on it. It does state that.

(The manual page comes from linux and should probably be replaced with "This page is intentionally blank", given such inanities as:

"Do not use "-r" because this flag does not do what you think."

but then proceeds to not disclose why! LOL).


So, it seems you're trapped with using tar|split.
