Your suggestion will clear the history file of the commands from the previous sessions, and save the commands from the current session. I think this is the opposite of what the OP wanted. As the OP hasn't come back, and seeing that his nym "Peter Hanke" could be a reference to toilet paper, I think he may not even exist. If he does exist, and that is his real name, "Sorry Peter".

Using rxvt, "clear" clears the screen. "tput reset" clears the screen _and_ the scroll back buffer.
