If you're a second late on the draw for shutdown -c, and already root on the console, a very fast # init 5 will cancel a shutdown after init changes runlevel.
NOTE: This answer is mostly obsolete now. init 5 isn't very useful on systemd, which, sadly, most systems now use.

关闭-c是在最近的关机中“取消关机”。该语法还支持用于公告目的的
shutdown -c，因此如果其他人使用该机器，这会很方便。shutdown -cis "cancel shutdown" on reasonably recentshutdowns.The syntax also supports
shutdown -c <message>for announcement purposes, so that's handy if other people use the machine.您可以使用
ps找到关闭进程并中止它，例如使用ps|grep shutdown。替代且不那么引人注目的版本：
You can use
psto find the shutdown process and abort it, for example withps|grep shutdown.Alternate and less eyeball-intensive versions of this:
如果您在
shutdown -c的绘制上晚了一秒，并且已经在控制台上 root，则非常快的# init 5将在 init 更改运行级别后取消关闭。注意：这个答案现在基本上已经过时了。
init 5在 systemd 上并不是很有用，遗憾的是，大多数系统现在都在使用 systemd。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.NOTE: This answer is mostly obsolete now.
