## Script name:		create_ARD_computer_list.sh
## Author:        	Mike Morales (mm2270)
## Last Modified:	2015-Sept-04

## Special Notes:	This script was designed to work with a Casper Suite server's API functions,
##                  	to create a valid Apple Remote Desktop computer group plist file that can be
##                  	imported into the application.
##                  	The script allows you to choose a Smart or Static Computer Group from your JSS
##                  	to use for the conversion process into an ARD plist.

## How to use:		Edit the API_USER, API_PASS and JSS_URL variables below to match your environment's.
##                  	Save the script, ensure it is executable, then run it from Terminal and follow the instructions.


## VARIABLES

## Set the API Username, Password and your JSS URL below (Note: leave off trailing slash in the URL)
API_USER="apiuser"
API_PASS="apipass"
JSS_URL="https://your.jss.address.com:8443"
