Quick tip, the Say command
macOS has a great tool, called say, which just says what you pass it. For example, say "Hello" and next you'll hear your device say "Hello".
Where this is really useful is when you want to do a long-running action and get notified when it's done. For example:
git clone https://github.com/torvalds/linux.git && say "clone complete"
So, what about for Windows? You can do something similar with PowerShell. First, set it up:
Add-Type -AssemblyName System.speech
$say = New-Object System.Speech.Synthesis.SpeechSynthesizer
Once you have that in place, you can use it like this:
git clone https://github.com/torvalds/linux.git
$say.Speak("clone complete")
