Turn off Wi-Fi via shell script

Need to send a Shell Script to disable the wi-fi network?  No problem!  Have multiple types of machines that may have different device ID’s for the wi-fi?  No problem!

#!/bin/bash

# By Chris
## This will send a power-down to the Wi-Fi Device.
## Tested on 10.8.2 with single Wi-Fi device/hardware.

## First we get the Wi-Fi device name.  We are not assuming it is en1.
# We do this by listing all the hardware on the device, then only showing the line of and immediately following "Wi-Fi".
# Then do a quick second grep to only show the line of the Wi-Fi setting with the "Device" tag.
# We then cut out the first part of the entries and keep with is on the right side (of the ":".
# And finaly we strip out the extra space (to be neat).

WiFiDev="`networksetup -listallhardwareports | grep -A 1 "Wi-Fi" | grep -C 0 "Device" | cut -d ":" -f 2 | tr -d " "`"

# echo $WiFiDev

## Now turn it off.

networksetup -setairportpower $WiFiDev off

echo "Turning off the port at $WiFiDev"

exit 0

Set Proxy on all available network services

When you want to set the proxy on all available network services (say with JAMF’s Casper Suite at imaging time?)

#!/bin/bash

## A few variables we'll need for later

ProxyURL=http\:\/\/foo\/bar\.pac
declare -a NetServs

# Dealing with IFS as we need to alter it to avoid space issues.
OrigIFS=$IFS
IFS=$'\n'

#Define what Network Services are available.
NetServs=( `networksetup -listallnetworkservices | cut -d "." -f 2-` )

# Go through each network service and set the autoproxy.

for NetServ in ${NetServs[*]}; do
networksetup -setautoproxyurl "$NetServ" $ProxyURL
echo "$NetServ" is now set to use the proxy at $ProxyURL
done

exit 0

Enjoy.
