shutdown
shutdown(1B) SunOS/BSD Compatibility Package Commands shutdown(1B) NAME
shutdown - close down the system at a given time SYNOPSIS
/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 indicated in 24-hour notation. 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. At shutdown time a message is written to the system log daemon, syslogd(1M), containing the time of shutdown, the instigator of the shut- down, and the reason. Then a terminate signal is sent to init, which brings the system down to single-user mode. OPTIONS
As an alternative to the above procedure, these options can be specified: -f Arrange, in the manner of fastboot(1B), that when the system is rebooted, the file systems will not be checked. -h Execute halt(1M). -k Simulate shutdown of the system. Do not actually shut down the system. -n Prevent the normal sync(2) before stopping. -r Execute reboot(1M). FILES
