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.

NAME

       shutdown - graciously close the system down

SYNOPSIS

       shutdown [-hrRmk] [-x code] [time-specification [message]]

DESCRIPTION

       Shutdown  is a program which allows a system operator to close down the system in an nice way.  Shutdown informs the users why and when the
       system is going down.  This warning is issued 10 minutes before shutdown time and every minute in the last 5 minutes.  At this time (5 min-
       utes), shutdown creates a file /etc/nologin to prevent new users from logging in.

       Shutdown keeps a logfile of shutdowns.  Every shutdown is registered in /usr/adm/wtmp, if this file exists.  After these actions, a call is
       done to reboot(2) which actually brings the system down.

       Time-specification may be something like 15:00, 15.00, +15, or now for a shutdown at 3pm (twice), 15 minutes from now, or immediately.

       The message may be used to describe why the system is going down, it may also be typed on standard input with the -m option.

OPTIONS

       -h     This flag prevents the system from rebooting after the shutdown.	The system can now be powered off.  This is the default.

       -r     This flag indicates that the system should reboot after shutting down.

       -R     Reboot the system by resetting it.  Normally the kernel will try to return to the Boot Monitor.  With -R the system will	receive  a
	      hardware reset.

       -x code
	      Halt  the  system  and  let the Monitor execute the given code as if typed at the monitor prompt.  You can for instance use -x 'boot
	      hd0' as a very fast way to reboot "from the top."

       -m     Allows the operator to type a shutdown message on standard input, that will be added to the messages displayed on all terminals.

       -k     This option gives the possibility of terminating an already started shutdown.  This is only possible if shutdown time  has  not  yet
	      arrived.

       -C     Check  if the system crashed.  This option is not used at shutdown time, but at reboot time.  It tells if the file systems should be
	      checked by testing if the last entry in the wtmp file is a shutdown entry.  (A crude replacement for a file system clean flag.)

FILES

       /usr/adm/wtmp, /etc/nologin, /usr/adm/authlog
