NAME

       caffeinate - inhibit desktop idleness while a command runs

SYNOPSIS

       caffeinate COMMAND [ARGUMENT...]

DESCRIPTION

       Caffeinate runs the given command and prevents the desktop becoming idle while it is run, hence stops the
       screensaver, screen lock or automatic suspend 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.
