acpi (在 server 上無咩用)

acpi - displays information on ACPI devices (from the /proc or the /sys filesystem)
- man 1 acpi
= /usr/bin/acpi

i.e.

-b | --battery               # show battery information

acpid

- man 8 acpid, man 8 acpi_listen
= /usr/bin/acpi_listen
= /usr/sbin/acpid (/etc/init.d/acpid)

notify user-space programs of ACPI events

acpid read ---> /proc/acpi/event      // kernel  input: netlink

設定:

/etc/default/acpid

MODULES="battery ac processor button fan thermal video"

/etc/acpi/events

• powerbtn       // config file

# We need to react on "button power.*" and "button/power.*" because of kernel changes.
event=button[ /]power
action=/etc/acpi/powerbtn.sh

/etc/acpi/powerbtn.sh <- script file

P.S.

不會讀取 ~ 尾的 file

reload config:

send SIGHUP

socket

/var/run/acpid.socket

acpid will send  the  text  of all  ACPI  events  to the client
