Cisco 3560 - Write Script To Shut Or Unshut All These Interfaces At Once?

Lets say I have a group of interfaces on a Cisco 3560. Lets say it is interfaces fa0/13-fa0/24. Is there any way to write a script so that I can shut or noshut all these interfaces at once?

Basically I want to be able to easily turn the ports on and off all at once as they are only used a couple of times a week but when they are used they are all used at once. When they are not in use I do not want to be dishing out our internal network to anyone who may wander into the area.
