Software update preference

Question

Is there a command line way of setting a computers software update preference NOT to check for updates on a scheduled basis?
I have a 130 mac machines on the network and keep getting calls from users every time a new software update comes out. I want to be able to send a unix command through ARD to the client machines and disable the automatic checking of updates.
Thanks!

The simplest update notification to turn off is Apple’s own Software Update. It’s also the most important. While problems with a third-party update might destabilize a single product, problems with Apple updates could cause issues with any or all your applications. Fortunately, the Software Update system preference is just the front-end to the softwareupdate command. As such, you can disable your own update notifications for Apple products in the Terminal by typing:
softwareupdate –schedule off
For whatever reason, though, this setting isn’t followed system-wide. Instead, it’s a user-level preference, meaning that turning off updates as the administrator doesn’t disable them for other accounts. Instead, we’re forced to write a more complex script to run the command as each user individually:
for USER in `ls -1 /Users | \
sed -e ‘/Shared/d’ -e ‘/Deleted Users/d’ -e ‘/.localized/d’`; \
do; \
sudo -u $USER softwareupdate –schedule off; \
done
The first line uses the ls command to get a list of all the directories in /Users. The second uses sed to remove the standard non-user directories from that list. The final line uses sudo to let you run the softwareupdate command masquerading as all the other users on a machine.
