>Usage
The caffeinate command on macOS is used to prevent the system from sleeping. It can keep the display, system, or disk awake based on various options. This command is particularly useful for long-running tasks where you want to ensure the system stays awake without changing power settings.
Note: Most caffeinate commands can run without administrative privileges, but some tasks,
especially those affecting system-wide settings, may require sudo. For example:
sudo caffeinate -t 3600.
