#!/bin/bash

# Jamf script to be run after rename-comp.py to verify the configured hostname before continuing to provision
# a Mac.
#
# Usage:
#
# 1) Add this script to your Jamf instance
# 2) Configure the CSV variable below to match what you have listed in your rename-comp.py script
# 3) Add this script to your policy so that it runs AFTER rename-comp.py
# 4) Configure Parameter 4 for this script to match the URL configured in Parameter 4 of rename-comp.py
# 5) Configure Parameter 5 for this script to match the custom trigger configured for your policy to manually
# set the Mac's hostname
# 6) Configure Parameter 6 for this script to match the custom trigger configured for your subsequent Jamf bind
# and/or other enrollment policies

# Define path to locally cached CSV of serial #s and hostnames. This must match what's listed in
# rename-comp.py (https://gist.github.com/haircut/1debf91078ce75612bf2f0c3b3d99f03#file-rename-computer-py)
# Jamf script.

# (https://gist.github.com/haircut/1debf91078ce75612bf2f0c3b3d99f03#file-rename-computer-py) script in the
