Script to download macOS scripts from a Jamf Pro server

Jamf_Pro_Computer_Script_Download.sh

#!/bin/bash

# This script is designed to use the Jamf Pro API to identify the individual IDs of 
# the scripts stored on a Jamf Pro server then do the following:
#
# 1. Download the script as XML
# 2. Identify the script name
# 3. Extract the script contents from the downloaded XML
# 4. Save the script to a specified directory

# If setting up a specific user account with limited rights, here are the required API privileges
# for the account on the Jamf Pro server:
#
# Jamf Pro Server Objects:
#
# Scripts: Read

# If you choose to specify a directory to save the downloaded scripts into,
# please enter the complete directory path into the ScriptDownloadDirectory
# variable below.

ScriptDownloadDirectory=""

# If the ScriptDownloadDirectory isn't specified above, a directory will be
# created and the complete directory path displayed by the script.

# If you choose to hardcode API information into the script, set one or more of the following values:
#
# The username for an account on the Jamf Pro server with sufficient API privileges
# The password for the account
# The Jamf Pro URL

# Set the Jamf Pro URL here if you want it hardcoded.
jamfpro_url=""	    

# Set the username here if you want it hardcoded.
jamfpro_user=""

# Set the password here if you want it hardcoded.

# If you do not want to hardcode API information into the script, you can also store
# these values in a ~/Library/Preferences/com.github.jamfpro-info.plist file.
#
# To create the file and set the values, run the following commands and substitute
# your own values where appropriate:
#
# To store the Jamf Pro URL in the plist file:
# defaults write com.github.jamfpro-info jamfpro_url https://jamf.pro.server.goes.here:port_number_goes_here
#
# To store the account username in the plist file:
# defaults write com.github.jamfpro-info jamfpro_user account_username_goes_here
#
# To store the account password in the plist file:
# defaults write com.github.jamfpro-info jamfpro_password account_password_goes_here
#
# If the com.github.jamfpro-info.plist file is available, the script will read in the
# relevant information from the plist file.
