请教：shell中键入poweroff后，系统究竟做了哪些事？

[djstava]

关闭所有程序

呵呵，这也算啊？

比如涉及哪些文件，类似其它linux的inittab文件。

>> cat /etc/event.d/rc0
# rc0 - runlevel 0 compatibility
#
# This task runs the old sysv-rc runlevel 0 ("halt/poweroff") scripts with
# the decision as to whether to halt or power off the system left up to the
# script (and thus /etc/default/poweroff).

start on runlevel 0

stop on runlevel [!0]

console output
script
        set $(runlevel || true)
        if [ "$2" != "0" ] && [ "$2" != "6" ]; then
            set $(runlevel --set 0 || true)
        fi

        if [ "$1" != "unknown" ]; then
            PREVLEVEL=$1
            RUNLEVEL=$2
            export PREVLEVEL RUNLEVEL
        fi

        exec /etc/init.d/rc 0
end script
>> ls -lv /etc/rc0.d/

找poweroff的代码看...

[little_gg]

man里面说的挺清除的,自己看吧
