sosou

Wrote a little shell script that calls the native macOS caffeinate binary to prevent macOS from sleeping. Not a ton of functionality, basically:
 
default, 1 hour specify # of hours turn caffeination off  
It has notifications and sounds, which you can of course disable in the workflow editor if you like.
 
Hope you all like it!
