Play Audio Notification on MacOS for Slack Notifications

soundOnSlack.sh

#!/bin/bash

##### INSTRUCTIONS
# 1. Just place this script in your home directory, make it executable, and run it:
#  curl -O https://lnkd.in/gHkrCECr https://gist.githubusercontent.com/bebrws/a0ac04b59da575f36eb104b228182c1f/raw/089c60103df44ab33df4a006aeb8e4b49a3822e0/soundOnSlack.sh
# chmod +x soundOnSlack.sh
# ./soundOnSlack.sh
#
# This will create a launch agent that will run the script every time you login.
# and it will utilize the system logging to listen for Slack notifications to play a sound passively.
# To *stop the service and remove it* you can run the generated script:
# ./stopSoundOnSlack.sh
