SunOS/BSD Compatibility Package Commands         shutdown(1B)
SunOS/BSD 兼容命令包.

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 ...  ]

DESCRIPTION
     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.

OPTIONS
     As an alternative to the above procedure, these options  can
     be specified:

      system  is  rebooted,  the  file  systems  will  not be
      checked.
            进行快速起动,起动时不会检查文件系统.
     -h   Execute halt(1M).
            执行halt(1M).
     -k   Simulate shutdown of the system. Do not  actually  shut
      down the system.
            模拟关机.不真正动作.
     -n   Prevent the normal sync(2) before stopping.
            防止通常的对super-block的update.
