Possible to abort shutdown on Linux?
提问by David
I'm familiar with and use shutdownin Linux, and typically just do
我熟悉并shutdown在 Linux 中使用，通常只是做
> shutdown -h now
> shutdown -h now
But is there a way to stop shutdown from happening, say if I aim to shutdown 10 minutes from now and then in 5 minutes time I discover I really don't want to shut down?
但是有没有办法阻止关机的发生，比如说，如果我打算在 10 分钟后关机，然后在 5 分钟后我发现我真的不想关机？

You can use ps to find the shutdown process and abort it, for example with ps|grep shutdown.
您可以使用 ps 来查找关闭过程并中止它，例如使用ps|grep shutdown.
Alternate and less eyeball-intensive versions of this:
替代和较少眼球密集的版本：
pkill shutdown
killall shutdown
kill `cat /var/run/shutdown.pid`

shutdown -c is "cancel shutdown" on reasonably recent shutdowns.
shutdown -c 在最近的shutdowns上“取消关闭” 。
The syntax also supports shutdown -c <message>for announcement purposes, so that's handy if other people use the machine.
该语法还支持shutdown -c <message>公告目的，因此如果其他人使用该机器，这将很方便。

From shutdown's man page on BSD systems:
来自shutdownBSD 系统的手册页：
A scheduled shutdown can be canceled by killing the shutdown process (a SIGTERM should suffice).
可以通过终止关闭进程来取消计划的关闭（SIGTERM 就足够了）。

If you're a second late on the draw for shutdown -c, and already root on the console, a very fast # init 5will cancel a shutdown after init changes runlevel.
如果你是一个第二晚抽签shutdown -c，并已根在控制台上，一个非常快的# init 5将初始化运行级别改变之后取消关机。
NOTE: This answer is mostly obsolete now. init 5isn't very useful on systemd, which, sadly, most systems now use.
注意：这个答案现在大部分已经过时了。init 5在 systemd 上不是很有用，遗憾的是，大多数系统现在都在使用它。
