NAME

  reboot - Restarts the	machine

SYNOPSIS

  /usr/sbin/reboot [-dlnq]

OPTIONS

  -d  Generates	a crash	dump of	the system before halting it.  Can be used
      with any of the other options.

  -l  Does not log the reboot using syslog

  -n  Does not sync the	disks or log the reboot	using syslog

  -q  Performs a quick reboot without first shutting down running processes;
      does not log the reboot using syslog

DESCRIPTION

  When the system is running and multiple users	are logged in, use the shut-
  down -r command to perform a reboot operation. If no users are logged	in,
  use the reboot command.

  The reboot command normally stops all	running	processes, syncs the disks,
  logs the reboot, and writes a	shutdown entry in the login accounting file,
  /var/adm/wtmp.

  The reboot command uses the sync call	to synchronize the disks, and to per-
  form other shutdown activities such as resynchronizing the hardware time-
  of-day clock.	 After these activities, the system reboots. By	default, the
  system starts	and the	file systems are automatically checked.	If the
  start-up activities are successful, the system comes up in the default
  run-level.

  You must have	root privileges	to use this command.

				    Caution

       Using the -n option can result in file system damage.

EXAMPLES

   1.  To enable the default reboot action, enter:
	    reboot

       This command causes the system to stop all running processes, sync the
       disks, log the shutdown,	and perform other routine shutdown and reboot
       activities.

   2.  To shut down the	system without logging the reboot, enter:
	    reboot -l

       This command shuts down the system and performs all shutdown and
       reboot activities, except logging the shutdown.

   3.  To reboot the system abruptly, enter:
	    reboot -q

       This command reboots the	system abruptly	without	shutting down running
       processes.
