#            Name:  set_computername-sn.sh
#     Description:  This script is designed to set a computer name during automated enrollment as follows:
#                   1- Get serial name
#                   2- Format the computer name
#                   3- Set computer name/hostname/local hostname and NetBIOSName using formatted name
#                   4- To be overly thorough, use jamf setcomputername to set name as well
#
