                exit 1
                ;;
esac

exit 0
#end of file

3./ Now just fire below command for set this file in AUTO START with above file name(here file name is: openerp-server)
You have to be at location /etc/init.d where you just created the daemon file

•     sudo update-rc.d openerp-server

This command sets the file as daemon file, so whenever the system starts it starts the server so you can start the browser and you will find the server running, without starting it manually

4./ Then to start server when the system is already running i.e manully fire below command

•     /ept/init.d/openerp-server start ----> to start the server
•     /ept/init.d/openerp-server stop  ----> to stop the server
•     /ept/init.d/openerp-server restart -----> to restart the server

Hope this helps !!
