Blog: Creates a launchd job that updates the AWS PowerShell .NET Core module on a daily basis.

Update-AWSPowerShell-Module.ps1

<#
.Description
This PowerShell script will create and register a new launchd job that keeps the AWSPowerShell.NetCore module
up-to-date on your MacOS system.

If you receive an error upon registration, it's probably just because the service doesn't already exist.
This script tries to unload and reload the service, whether or not it exists, hence the error on initial run.
