the very reason i started with linux, the very reason im still with linux, is that there is something to learn, teh chalenge, and the satisfaction of personal growth.
"moving to perl" doesn't mean anything "bad"
i will finish this with bash (because i wont let this sucker win). and after that, i will try to make it in perl. just because i can (or rather "just because i still dont know how" )

there is only one more thing i want from this script. show the total of memory used, and the total of cpu used, while keeping it light

for the cpu. i had some doubts, but i have decided to show the iddle percentage. this is a personal thing, i will use it, so if i want/know iddle%, thats what im gonna get :P

for the memory, i have been researching.
i was using wmmem, so i went and read the code to and read how it calculated. i came up with the math behind it.
((total - cache - buffer) * 100 ) / total
now my problem is getting those 3 from top

unfortunately, all my work is in my personal laptop (at home), and usually, i dont spent time in this during the week, so i cant give you any particulars on what i have done so far to retrieve that data
i dont ask you to rewrite my script. actually i would hate that.
as i said, i want to solve this, or at least try

thanks for the great help so far !
