Status bar

Get volume & mute status

To get only values, provide -n flag.

Volume level: (0 - 1)

sndioctl -n output.level

Mute (0 or 1):

sndioctl -n output.mute

Battery percentage

apm -l

Formatted date

date '+%Y-%m-%d %H:%M'

Change status bar text

To change the status bar text:

xsetroot -name Test

Putting it alltoghether

We can put a little script inside ~/.xsession to periodically display those values on status bar:

while true
do
    mute=`sndioctl -n output.mute`
    volume=`sndioctl -n output.level`
    if [ $mute == 1 ] ; then vol=0; else vol="$volume"; fi
    date=`date '+%Y-%m-%d %H:%M'`
    battery=`/usr/sbin/apm -l`
    xsetroot -name "vol: ${vol} / bat: ${battery} / ${date}`";
    sleep 1
done &
