Question: Reading the Output of Top

[John G Heim]

I doubt that there is an answer to your first question. You could 
probably write a script to do it.

As for your second question, I run top thusly, 'top -bn1 | more'. This 
runs top in batch mode and has it retrieve the data just once. Piping 
the output to more keeps the data from scrolling off the top. What you 
get is a snapshot of the data at the moment you run the top command.

PS: You can also set the refresh rate for top to something high enough 
for you to listen to the output.
