Bug in 12c found ;-)

In  $ORACLE_HOME/bin/dbshut I noted the typo

# Stop Oracle Net Listener
  if [ -f $ORACLE_HOME_LISTNER/bin/tnslsnr ] ; then
    echo "$0: Stoping Oracle Net Listener" >> $LOG 2>&1
    $ORACLE_HOME_LISTNER/bin/lsnrctl stop >> $LOG 2>&1 &
  else
    echo "Failed to auto-stop Oracle Net Listener using $ORACLE_HOME_LISTNER/bin/tnslsnr"
  fi

It was there in 10.2, 11.1, 11.2 and now in 12.2. Don't they ever check their syntax?

By the way, Stoping is something different: http://en.wikipedia.org/wiki/Stoping
