Re: [wmii] Adding cpu usage to status bar

Hey,

You need the '-b' Option for top, because it's not for the Terminal.

We talked long about that in the IRC Channel, we came to this:

top -b -d 1 -n 2|grep Cpu|awk 'BEGIN { FS = " " } { print $2 }'|tail
-n 1 | sed 's/us,//g')

This should echo the right cpu usage...top -n 1 seems to be not
right(sometimes?).
We also had another Way of doing it, probably more reliable, but i am
sorry, i can't tell you that. It has to do something with /proc/stat,
but for me this was enough.
