automatic startup and shutdown of LISTENER

I would like to be able tostartup and shutdown the listener when my SA shutsdown and brings the Unix box back up. What happens when my SA brings up

the OS is that he gets the lsnrctl prompt rather than listener starting. He can then type the start command and listerner starts. But it should start without him having to key in the command. I have the following in both the /etc/init.d/dbstart and /etc/rc2.d/s99dbstart files:
su - oracle -c $ORACLE_HOME/bin/ lsnrctl start
(I use the default listener name "LISTENER")
