Here are two variations of the standard ksh shell prompt that I myself
find useful on several of my devices, in particular the portables. The
first prompt shows the temperature on cpu0, the second the amount of
battery claimed to remain:
export PS1='`( /sbin/sysctl hw.sensors.cpu0.temp0 | sed -e \
"s/^.*\([0-9][0-9]\.[0-9]\)\([0-9]\).*$/\1/g;")`$ '
66.0$
export PS1='`/usr/sbin/apm -l`% $ '
96% $
Here is a test using date:
export PS1='`/bin/date +"%H:%M:%S"`$ '
14:20:33$
apm is to cool running mode in rc.local
