Being fairly new to linux, I have been trying to learn more standard commandline tools. Today I have been running top on the core to get an idea of processor usage, etc.. Here is a copy and paste from one of my top sessions:
top - 10:29:24 up 2:00, 1 user, load average: 0.03, 0.15, 0.24

Does it look normal?
How do I see more pages? (It says there are 263 tasks running, but this one page shows only 40 or so tasks...)
Near the top, what does the "96.5%id" mean? (Cpu(s): 0.8%us, 1.8%sy, 0.0%ni, 96.5%id, 0.0%wa, 0.3%hi, 0.5%si, 0.0%st
)
thanks
