shutdown script

hi i want to know if theres a way to restart or shutdown photoshop
from a main server the deal is my school has macs for the computer grahics class and they just got a server so i came up the idea to shutdown the programs right from the server via ssh now im not linux or unix programmer but i know my way around so what i need is a way to shutdown programs and make sure it shutsdown the program and at the end of the day to shutdown the 15 mac's they have now right now i cant test it the mac are still mac os 9.2 but i know mac os x is beening installed by the end of the year and i can do it next year or even in the end

so if anyone know how to do this post it please !

When OS X is installed you can type this to quit photoshop:


And to shutdown the computer:


Or, you can set up cron jobs on the computers themselves to execute these at certain time.

heard of remote desktop? pretty sweet app. if you havn't heard of it, it's basically a remote administration application. one administrator can take complete control over all of the 15 screens. apple will give a discount if you buy it from your school.
