       Caffeinate  runs  the  given  command and prevents the desktop becoming idle while it is run, hence stops
       screen savers or power-saving activating even if the machine is not being used.

       It is usually more convenient to use the fully-automatic caffeine(1); caffeinate may be useful when it is
       impractical or impossible to run a program in full-screen mode, or to prevent automatic  suspend  kicking
       in during a long-running unattended command, such as a system update.

       Note,  when  using  caffeinate with cron(1) or another task scheduler, it is important to ensure that the
       DISPLAY environment variable is correctly set for the task. For many setups, DISPLAY=:0 (or whatever your
       current value of DISPLAY is) will work; for cron, simply prepend this setting to the command.
