#!/bin/bash

# This script downloads and installs the latest Oracle Java 8 for compatible Macs

# Determine OS version
osvers=$(sw_vers -productVersion | awk -F. '{print $2}')

# Specify the "OracleUpdateXML" variable by adding the "SUFeedURL" value included in the
# /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Info.plist file.
#
# Note: The "OracleUpdateXML" variable is currently specified in the script as that for
# Java 8 Update 20, but the XML address embedded with Java 8 Update 20 is not special in
# this regard. I have verified that using the address for Java 8 Update 5 will also work
# to pull the address of the latest Oracle Java 8 installer disk image. To get the "SUFeedURL"
# value embedded with your currently installed version of Java 8 on Mac OS X, please run
# the following command in Terminal:
#
# defaults read "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Info" SUFeedURL
#
# As of Java 8 Update 20, that produces the following return:
#
# https://javadl-esd-secure.oracle.com/update/mac/au-1.8.0_20.xml
#

OracleUpdateXML="https://javadl-esd-secure.oracle.com/update/mac/au-1.8.0_20.xml"

# Use the XML address defined in the OracleUpdateXML variable to query Oracle via curl
# for the complete address of the latest Oracle Java 8 installer disk image.

fileURL=`/usr/bin/curl --silent $OracleUpdateXML | awk -F \" /enclosure/'{print $(NF-1)}'`

# Specify name of downloaded disk image
