ANSWER 1

Score 10

From my own experience, when I disabled Lion's Resume feature, this stopped Terminal storing session history.

ANSWER 2

Score 9

Lion's window resume feature is set on an application by application basis. You can stop this in Terminal with the following command:

defaults write com.apple.Terminal NSQuitAlwaysKeepsWindows -bool false

Because you're editing the Terminal settings while having Terminal open, you'll need to close and restart Terminal twice before seeing the effect.

ANSWER 3

Score 7

Command-K clears the Scrollback.

ACCEPTED ANSWER

Score 4

Add the following at the very end of .bash_profile:

printf '\033c'

This will really clear the Terminal. I even defined the following function, since I didn't like the scrolling behavior of the default clear:

function clear {
    printf '\033c'
}

I think it's the same as a hard reset of the Terminal (Cmd-Opt-R), but I'm not entirely sure.
