REBOOT(8)		FreeBSD	System Manager's Manual		     REBOOT(8)

     reboot, halt -- stopping and restarting the system

     halt [-dnpq]
     reboot [-dnq]

     The halt and reboot utilities flush the file system cache to disk,	exe-
     cute the rc.d(8) scripts specified	by the pkg_scripts variable defined in
     rc.conf(8)	in a reverse order, run	the system shutdown script, send all
     running processes a SIGTERM (and subsequently a SIGKILL), and, respec-
     tively, halt or restart the system.  The action is	logged,	including en-
     tering a shutdown record into the login accounting	file.

     The options are as	follows:

     -d	     Causes system to create a dump before rebooting.  This option is
	     useful for	debugging system dump procedures or capturing the
	     state of a	corrupted or misbehaving system.  See savecore(8) for
	     information on how	to recover this	dump.

     -n	     Prevent file system cache from being flushed.  This option	should
	     probably not be used.

     -p	     Causes the	system to power	down, if it is being halted, and the
	     hardware supports automatic power down.

     -q	     Quick.  The system	is halted or restarted quickly and ungrace-
	     fully, and	only the flushing of the file system cache is per-
	     formed.  This option should probably not be used.

     Normally, the shutdown(8) utility is used when the	system needs to	be
     halted or restarted, giving users advance warning of their	impending

     reboot(2),	utmp(5), boot_alpha(8),	boot_amd64(8), boot_hppa(8),
     boot_i386(8), boot_luna88k(8), boot_macppc(8), boot_sparc64(8), rc.d(8),
     rc.shutdown(8), savecore(8), shutdown(8), sync(8)

     A reboot command appeared in Version 6 AT&T UNIX.
