Init 0 vs shutdown

When the process is stopped, I need to know if it is being stopped because of a system shutdown or reboot, and I need to be able to distinguish between the two. Previously, under init on RHEL6, I was able to do this by looking at the pathname used to invoke my init script, and sent the process a different signal accordingly, i.e.: The shutdown command used to kill all the running processes, unmount all the file systems and finally tells the kernel to issue the ACPI power command. 2.init 6 tells the init process to shutdown all of the spawned processes/daemons as written in the init files (in the inverse order they started) and lastly invoke the shutdown -r now command to reboot the machine init是所有进程的祖先﹐它的进程号始终为1﹐所以发送TERM信号给init会终止所有的用户进程﹑守护进程等。shutdown就是使用这种机制。init定义了8个运行级别(runlevel)，init 0为关机﹐init1为重启。关于init可以长篇大论﹐这里就不再叙述。 Shutdown You have more than one command option that you can use. The best command is this, executed as root: shutdown -y -i5 -g0. This will immediately shut the system down. You can also use the older command that still works: sync;sync;init 5. You can even use: poweroff.

poweroff, shutdown and halt are all shortcuts to systemctl and I think that in the old days poweroff actually called shutdown which would be the preferred way. Does ths shutdown command do the same thing for you? You can change system runtime levels with it in much the same way as init except there is a slight delay even if you specify 0 delay :-) For init level 0, no wait time, dont ask for confirmation: shutdown -g0 -i0 -y For init level 6, no wait time, dont ask for confirmation: shutdown -g0 -i6 -y This question is more in the line of how init messages get sent to a console during startup/shutdown.
