Written by Christopher Kemp for Accenture 
This script will take a list of serial numbers as input and check the JSS for their existence.
HUGE tip of the hat to Chris Lasell from Pixar for the tips on how to call the functions.
Input file should have no headers, just a list of computer names formatted as Unix LF.
