-d      Create an assertion to prevent the display from sleeping.
-i      Create an assertion to prevent the system from idle sleeping.
-m      Create an assertion to prevent the disk from idle sleeping.
-s      Create an assertion to prevent the system from sleeping. This assertion is valid only when system is running on AC power.
-u      Create an assertion to declare that user is active. If the display is off, this option turns the display on and prevents the display from going
        into idle sleep. If a timeout is not specified with '-t' option, then this assertion is taken with a default of 5 second timeout.
