stop application befor shutdown

Stop the application before shutdown the server ..

I have application need to be started with the system and also need to be stop before shutdown the system

This is the path of the application:

/usr/appstart

/usr/appstop

to start the application with the startup of the system I have mentioned this path /usr/appstart in this file /etc/rc

but my question is ?

how to can I let the system stop my application before shutdown

I mean if I type shutdown I want the system to stop this application /usr/appstop before shutdown the server .

is there any file similar rc file need to mentioned that path in it to stop it before start shutdown process .

Pls advice ...

You can put that command in /etc/rc.shutdown and it will do what you want. Check out 'man shutdown' for more info.

vi /etc/rc

######## Application start script #################
/usr/appstart

vi /etc/rc.shutdown

######## Application stop script #################
/usr/appstop

Many thanks ....
