Script to swap your Bluetooth devices connections between two Macs. Works great with iMacMonitor.app to quickly switch your iMac between being a laptop monitor or full computer. http://bogner.sh/2013/07/os-x-how-to-use-an-imac-as-monitor/

bluetooth-swap.sh

#!/usr/bin/env bash

# This script works after you've paired the Bluetooth devices with
# both the local and remote computer. Turning one off and the other on
# forces the devices to reconnect with the only computer that has BT on.


# Look up local SSH hosts with Bonjour using `dns-sd -B _ssh`
# You may want to set up an SSH keypair to log in without typing a password
REMOTE=Stone.local

MODE=$1

case "$MODE" in
	give)
		echo "Give it away now..."
		# Power up remote so they attach there
		ssh $REMOTE 'blueutil power 1'
		# Release devices from local Bluetooth
		blueutil power 0
		;;
	take)
		echo "Bring it back..."
		# Power up local to receive them
		blueutil power 1
		# Release devices from remote
		ssh $REMOTE 'blueutil power 0'
