UPSSHUTDOWN(8)                           BSD System Manager's Manual                          UPSSHUTDOWN(8)

NAME
     upsshutdown -- UPS emergency low power shutdown script

DESCRIPTION
     upsshutdown is a script that runs automatically when the system performs an emergency UPS low power
     shutdown.  The script is run before shutdown(8) is invoked.  upsshutdown only runs if one of the three
     shutdown rules is enabled and true: "percentage remaining," "time remaining," or "time since loss of
     power."  These settings can be changed using pmset(1) or Energy Saver in System Preferences.

     The system administrator may modify upsshutdown.  The script should only contain commands that must run
     in the case of an emergency UPS shutdown.  It should not contain any commands that would otherwise be
     executed during a normal shutdown since the normal shutdown procedure follows invocation of
     upsshutdown.
