By reversing vertically, I mean that the prompt line is always on the first line in the terminal window, and the command output is printed below the current prompt. Something like this:

Original

name@host$ ls

Desktop  Documents  Downloads  examples.desktop  Music  Pictures  Public  Templates

name@host$ (waiting for next command)

Reversed

name@host$ (waiting for next command)

Desktop  Documents  Downloads  examples.desktop  Music  Pictures  Public  Templates

name@host$ ls

I'm looking for this because looking at the bottom of the screen for a long time makes my neck hurt.

Thanks
