TIL: caffeinate

Very useful.

While it may avoid sleep, it doesn’t prevent inactivity, in my experience. For instance, my chat app at work will still show me inactive while running caffeinate. I have to do non-interactive training semi-regularly and need to interact to keep from looking like I’m away from my desk.

Have you used the `-u` flag? From the manual:

  -u      Create an assertion to declare that user is active.

Doesn’t work with Slack at least. I’ve had an iTerm window running `caffeinate -disu` for years. I think it used to work and stopped working in the last few months.
