ACPID(8)                OpenBSD System Manager's Manual               ACPID(8)

NAME
     acpid - Advanced Configuration and Power Interface daemon

SYNOPSIS
     acpid [-d]

DESCRIPTION
     acpid monitors the advanced configuration and power interface (ACPI) de-
     vice, acting on signaled events.  For suspend and poweroff request events
     delivered by the BIOS, acpid runs the appropriate program (if one ex-
     ists).

     If the -d flag is specified, acpid enters debug mode, logging to facility
     LOG_LOCAL1 and staying in the foreground on the controlling terminal.

     Actions can be configured for the following two events: suspend and
     powerdown.  The suspend actions are run when the sleep button is pressed,
     while the powerdown action is run when the power button is pressed.

FILES
     /etc/acpi/suspend and /etc/acpi/powerdown are the files that contain the
     host's customized actions.  Each file must be an executable binary or
     shell script suitable for execution by the execve(2) function.  If you
     wish to have the same program or script control all transitions, it may
     determine which transition is in progress by examining its argv[0], which
     should be set to one of suspend and powerdown.

     /dev/acpi is the default device used to control the ACPI kernel driver.
