TIL about caffeinate a built-in macOS command-line tool that prevents your Mac from sleeping.

Some commands I use:

• caffeinate -u - to simulate user activity. keeps the system awake as if there is constant user input.
• caffeinate -d - prevents the display from sleeping, but allows other parts of the system to sleep.
• caffeinate -s - prevents sleep when there’s an active user session (helpful in remote work or screen sharing).
• caffeinate -dt 600 - prevents display sleep for 10 minutes.
• caffeinate -i script.sh - keeps system awake only while the script runs, then exits.
