Question about using pid

[John covici]

You might consider using pidof to get the process id of the program
once it is running and I enclose what I use for the speakfreely
monitor -- this might be of help.

#!/bin/bash
secs=15
while true
do
sleep $secs
if [ `pidof sfspeaker | wc -w` != 2 ]
then
#if there are not two sfspeaker processes
aplay -q /usr/src/speak_freely/busy.au
fi
done
