Clear screen automatically, how to do this ?

Question

When closing a CLI program the command prompt always appears in the middle of the screen.
How do I avoid that ??
I have a alias cls='clear' in my .bashrc, but how do I make it so the screen clears every time when closing a program ??

Hi,
I thought a bit about it, normally you would use bash's PROMPT_COMMAND, but clearing the prompt after every command would be a bit counter productive. You could use the following small function in your .bashrc though:
clearprompt() {
eval $1
clear
And then just set an alias in your .bashrc for the cli app you want the prompt to clear after its executed, for example:
alias top="clearprompt /usr/bin/top"
you have to use the full path to the command in the alias when you want to give the alias the same name as the command itself otherwise bash segfaults. It's probably a dirty hack I know .
