In that case, `clear` might clear the underlying terminal scrollback buffer, but it does not clear the tmux scrollback buffer. The `screen` terminal multiplexer is similar. Both screen and tmux HAVE a way to clear their scrollback buffer, but it is two different ways between those popular programs... both different from the `clear` command in the underlying terminal. I don't use MacOS anymore, but when I did I used iTerm2, which has a fork of the tmux code to implement its pane division functionality. I do not know whether that very popular terminal clears the actual scrollback with the `clear` command. I feel like I remember it not doing that, but it's been a couple years. All of which suggests to me that doing the "same thing" in a platform neutral way is not an insignificant effort. -- The dead increasingly dominate and strangle both the living and the not-yet born.
