In the general case, that's going to be terminal-specific. If you only 
want stdout (and/or stderr) output you'd need to know what escape 
sequence to sent to the terminal (possibly with reference to 
termcap/terminfo- I don't know whether there are libraries to handle 
this) but if you wanted full control like you get with the FP IDE I 
think you'd be using the old TurboPower stuff.

In extremis, if you're already invoking an external program and want to 
clear output after it runs, and if you know that you're running on a 
unix, you could simply invoke the clear program.

Going back to your original question, I see no reason why you couldn't 
open and parse e.g. /proc/partitions as an ordinary text file.
