Linux in a Nutshell, 6th Edition

Name

acpid

Synopsis

acpid [options]

Daemon that informs user-space programs about ACPI (Advanced Configuration and Power Interface) events, such as battery warnings, power-supply changes, and laptop lid closings. As ACPI hardware replaces older APM (Advanced Power Management) hardware, acpid replaces apmd. Like other daemons, this application is controlled primarily through a configuration file that determines which events merit action, and what those actions are.

Options

-c directory, --confdir=directory

Set the directory used for configuration files. The default directory is /etc/acpi/events. All files in this directory, except those beginning with a period (.), are parsed as configuration files. Typically, a single file is used for each ACPI event to be acted upon.

In the configuration files, blank lines and those beginning with # are ignored. Other lines are expected to consist of a regular expression and a command to be executed when an ACPI event matches the expression.

-d, --debug

Debug mode: run the daemon in the foreground and send all log output to stderr and stdout, rather than a logfile.

-e filename, --eventfile=filename

Set the file used to find events. Normally this is /proc/acpi/event.

-g group, --socketgroup=group

Set the group ownership of the socket to which acpid publishes events. This allows you to restrict which users on the system can access ACPI event information.

-l filename, --logfile=filename

Set the logfile location. Normally, it is /var/log/acpid.

-m mode, --socketmode= ...
