NAME

名称

shutdown - close down the system at a given time

在给定的时间内容关毕系统.

SYNOPSIS

大纲

/usr/ucb/shutdown [ -fhknr ] time [ warning-message ... ]

DEs criptION

shutdown provides an automated procedure to notify users

when the system is to be shut down. time specifies when

shutdown will bring the system down; it may be the word now

(indicating an immediate shutdown), or it may specify a

future time in one of two formats: +number and hour:min.

The first form brings the system down in number minutes, and

the second brings the system down at the time of day indi-

cated in 24-hour notation.

当系统将要关毕前,shutdown提供一个自动的进程对用户进行提示.

在关毕系统时要求提供系统能存活的时间.时间可以指定为now(意思是

立即关毕)或者可以用下面两种格式的一种.+number 和hour:min.

第一种格式会指定在未来的number分种后关毕系统后者指定当天

准确的时间.

At intervals that get closer as the apocalypse approaches,

warning messages are displayed at terminals of all logged-in

users, and of users who have remote mounts on that machine.

在关毕系统前远程用户和对该机器有mount操作的用户将每隔一段

时间就会得到警告信息.

At shutdown time a message is written to the system log dae-

mon, syslogd(1M), containing the time of shutdown, the

instigator of the shutdown, and the reason. Then a ter-

minate signal is sent to init, which brings the system down

to single-user mode.

关毕系统时将会向系统的登陆守护程序发一个信息,信息中包括系统关毕时间,

执行者,和原因.然后一个中断信号将发给init,init将会把系统重新起动到

单用户模式.
