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 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.
