Not sure if anyone needs an EA for Proxy information:
#!/bin/sh
# Reference: https://macmule.com/2014/12/07/how-to-change-the-automatic-proxy-configuration-url-in-system-preferences-via-a-script/
/usr/sbin/networksetup -detectnewhardware
IFS=$'
'
#Loops through the list of network services
for i in $(networksetup -listallnetworkservices | tail +2 );
do
# Get a list of all Network Devices & Auto Proxy Information
autoProxyURLLocal=`/usr/sbin/networksetup -getautoproxyurl "$i" | head -1 | cut -c 6-`
# Echo's Auto ProxyURL for every Network Services
if [ "$autoProxyURLLocal" != "(null)" ]; then
echo "<result>$autoProxyURLLocal</result>"
fi
done
unset IFS
exit 0
