[SOLVED] dwm Basic Statusbar spikes CPU usage

When I attempt to add battery status to dwm by adding the following to my ~/.xinitrc and start X I get ~100% CPU usage.

while true
do
acpi | awk '{ print $3, $4 }' | sed s/","//g
done | exec dwm

When I uncommented the previous lines and left 'exec dwm' cpu usage returns to normal.

Would you happen to know a reason for the increase in usage?

Re: [SOLVED] dwm Basic Statusbar spikes CPU usage

Because it will poll every nanosecond. Put a sleep 10 in there or something

while true
do
acpi | awk '{ print $3, $4 }' | sed s/","//g
sleep 10
done | exec dwm
