# To pass in the correct input, you need to use Automator on macOS.
# First, add in the "Find Calendar Events" Action and set it to find events where "Date starting" "is today".
# Then, pass that to the "Event Summary" Action.
# Finally, add a "Run Shell Script" Action and paste the following into it.
