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

NAME
     reboot, halt - stopping and restarting the system

SYNOPSIS
     halt [-dhnq]
     reboot [-dnq]

     fasthalt
     fastboot

DESCRIPTION
     The halt and reboot utilities flush the filesystem cache to disk, send
     all running processes a SIGTERM (and subsequently a SIGKILL) and, respec-
     tively, halt or restart the system.

     The options are as follows:

     -d	     The -d option causes the system to make a ``crash dump'' (debug-
	     ging image) when halting or rebooting.

     -h	     Once the system has halted, attempt to power down the machine.
	     If the hardware does not support this feature this option is
	     silently ignored.

     -n	     If the -n option is specified, the filesystem cache is not
	     flushed.  This option should probably not be used.

     -q	     If the -q option is specified, the system is halted or restarted
	     quickly and ungracefully, and only the flushing of the filesystem
	     cache is performed.  This option should probably not be used.

     The reboot or halt action is logged, including entering a shutdown record
     into the login accounting file; see syslogd(8) and wtmp(5) for more in-
     formation.

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

SEE ALSO
     wtmp(5),  boot(8),	 shutdown(8),  sync(8)

COMPATIBILITY
     Historically, the fastboot and fasthalt commands were shell scripts that
     arranged for the filesystems not to be checked on reboot.	As filesystems
     are no longer checked unless necessary, they have been deleted and are
     now simply links to the reboot and halt commands.

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