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

NAME
reboot - reboot the system SYNOPSIS
time] message] time] message] DESCRIPTION
The command terminates all currently executing processes except those essential to the system, then reboots the system, or halts, or makes the partition ready for reconfiguration. When invoked without arguments, syncs all disks before rebooting the system. Options The command recognizes the following options: Shut down the system and halt. Shut down the system and reboot automatically (default). Shut down the system to a ready-to-reconfigure state and reboot if possible. If the partition is unable to reboot, it will stop at a ready-to-reconfigure state. However, if the option is also specified, the system will always stop at ready-to-reconfigure state. This option is available only on systems that support hardware partitions. Shut down the system to a ready-to-reconfigure state and do not reboot. This option can be used only in combination with the option. This option is available only on systems that support hardware partitions. Do not sync the file systems before shutdown. The and options are ignored with this option. Sync the file systems before shutdown; for file systems that were cleanly mounted, modify the flag from to (default). Quick and quiet. Suppress broadcast of warning messages, terminate processes by brute force (with and immediately call with arguments as indicated by the other options (see reboot(2)). No logging is performed. The and options are ignored with this option. Specify what time will bring the system down. time can be the word (indicating immediate shutdown) or a future time in one of two for- mats: and The first form brings the system down in number minutes; the second brings the system down at the time of day indicated (based on a 24-hour clock). Display message at the terminals of all users on the system at decreasing intervals as reboot time approaches. The message must not contain any embedded double quotes. At shutdown time a message is written in the file (if it exists), containing the time of shutdown, who ran and the reason. Only users with appropriate privileges can execute the command. WARNINGS
does not invoke the shutdown scripts associated with subsystems to bring them down in a cautious manner. See shutdown(1M). If the option is used in a virtual partition environment on a partitionable system, then the requested reconfiguration will not take place until all the virtual partitions on that hard partition are shut down and the virtual partition monitor is rebooted.
