G=$(stty -g);stty rows $((${LINES:-50}/2));top -n1; stty $G;unset G
Doesn't take more than the below toprc file I've added below, and you get all 4 top windows showing output at the same time.. each with a different color scheme, and each showing different info. Each window would normally take up 1/4th of your screen when run like that - TOP is designed as a full screen program. But here's where you might learn something new today on this great site.. By using the stty command to change the terminals internal understanding of the size of your terminal window, you force top to also think that way as well.
# save the correct settings to G var.
G=$(stty -g)
# change the number of rows to half the actual amount, or 50 otherwise
stty rows $((${LINES:-50}/2))
# run top non-interactively for 1 second, the output stays on the screen (half at least)
top -n1
# reset the terminal back to the correct values, and clean up after yourself
stty $G;unset G
This trick from my [ http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html bash_profile ], though the online version will be updated soon. Just think what else you could run like this!
Note 1: I had to edit the toprc file out due to this site can't handle that (uploads/including code). So you can grab it from [ http://www.askapache.com/linux-unix/bash-power-prompt.html my site ]
Note 2: I had to come back and edit again because the links weren't being correctly parsed
