[mythtv-users] How can I know if the mythtv is idle?

This is how I check for idle - these functions check a) if there's
anything going on that I might want to allow to complete before
shutting down and b) if anything's being recorded. I call these from
another shell script which then decides what to do.

if [ $FRONTEND -eq 0 ] && [ $COMMFLAG -eq 0 ] && [ $TRANSCODE -eq 0 ]
&& [ $TV_GRAB -eq 0 ] && [ $NUVEXPORT -eq 0 ]
then
    return 0
else
    return 1
fi
}

while [ $TNRNUM -le 2 ]
do
   TNRSTS=`wget --quiet --output-document=- http://elm.edwards.home:6544/xml | \
   grep "<Encoder .*id\=\"$TNRNUM\"" `

   # If the state="0" in the XML then nothing's recording on that tuner.
   echo $TNRSTS | grep --quiet state\=\"0\"
   if [ $? -gt 0 ]
   then
      return 1
   fi
   TNRNUM=`expr $TNRNUM + 1`
done

return 0
}
