Script for unpair/pair selected bluetooth devices

device_switch.sh

#!/bin/bash
#
# This script unpair selected device if is paired and vice versa
# for example, to quickly switch mouse and keyboard between macs
# Install `blueutil` with Brew before use this script!
# For get device ID run `blueutil --paired` and get "address" (as is)
# P.S. This script will be more convenient with Automator...

# for Homebrew on M1
export PATH="$PATH:/opt/homebrew/bin"
