Try something like:

#!/bin/sh
#
# Set ORA_HOME to be equivalent to the ORACLE_HOME
# from which you wish to execute dbstart and
# dbshut
# set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME
ORA_HOME=/u01/app/oracle/product/8.1.7
ORA_OWNER=oracle

export ORA_HOME
export ORA_OWNER

if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup: cannot start"
exit
fi

case "$1" in
'start')
# Start the Oracle databases:
su - $ORA_OWNER -c $ORA_HOME/bin/dbstart
su - $ORA_OWNER -c $ORA_HOME/bin/lsnrctl <<EOF
start
quit
EOF
;;

'stop')
# Stop the Oracle databases:
su - $ORA_OWNER -c $ORA_HOME/bin/lsnrctl <<EOF
stop
quit
EOF
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut
;;
esac



OR:
~~~
#!/sbin/sh
ORACLE_HOME=/opt/oracle/product/9.0.1

case $1 in
        start)
                su - oracle -c $ORACLE_HOME/bin/dbstart
                su - oracle -c "$ORACLE_HOME/bin/lsnrctl start"
        ;;
        stop)
                su - oracle -c "$ORACLE_HOME/bin/lsnrctl stop"
                su - oracle -c $ORACLE_HOME/bin/dbshut
        ;;
