Linux-Watch System Stats Similar To The Top Command

A way of watching cpu stats similarly to the way `top` outputs

You will see the stats update every 2 seconds, and what has changed will be highlighted.

$ watch -d iostat

Another method I just came up with while playing involves a while loop at the command line and a command from the reference url below.

This also finds all the cpu hogs.

$ while [[ "0" != "1" ]]; do clear; ps -eo pcpu,pid,user,args | sort -k 1 -r | head -10; sleep 1; done

and

$ ps -eo pcpu,pid,user,args | sort -r -k1 | less

I know my mac with Snow Leopard has iostat and my Ubuntu box. I've installed the sysstat package.

# apt-get install sysstat

You can then use commands like, mpstat and sar.
