# Author:   Stephen Bygrave - Moof IT
# Name:     disableJavaAutoUpdates.sh
#
# Purpose:  Checks to see the status of the Java AutoUpdater, and disables if
#           necessary.
# Usage:    Can be run as a ongoing login policy in Jamf, as this will remediate
#           automatically when a user logs in, if the updater is enabled.
#
# Version 1.0.0, 2018-05-05
#   SB - Initial Creation

# Use at your own risk. Moof IT will accept no responsibility for loss or damage
# caused by this script.
