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

Some commands I use:

• -d - prevent display sleep
• -i - prevent system idle sleep
• -m - prevent disk idle sleep
• -u - declare that user is active
• caffeinate -dt 600 - prevents display sleep for 10 minutes.
• caffeinate -i script.sh - keeps system awake only while the script runs, then exits.
