#            Name:  set_computerName.sh
#     Description:  This script is designed to set a computer name during DEP enrollment as follows:
#                   1- Get logged-in username
#                   2- Format the computer name as $username-mac
#                   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
#            Note:  Works best for 1x1 laptop deployments where only one person typically signs into the laptop.
