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


     reboot, halt - stopping and restarting the system


     halt [-dnpq]
     reboot [-dnq]


     The halt and reboot utilities flush the filesystem cache to disk, run the
     system shutdown script, send all running processes a SIGHUP, SIGTERM and
     one or more SIGKILL, and, respectively, halt or restart the system. The
     action is logged, including entering a shutdown record into the login ac-
     counting 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 filesystem 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 ungraceful-
             ly, and only the flushing of the filesystem cache is performed.
             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


     /etc/rc.shutdown     script which is run at shutdown time by /etc/rc
     /var/db/host.random  where 2 KiB entropy are stored before reboot(2)


     reboot(2), utmp(5), boot_i386(8), boot_sparc(8), rc.shutdown(8),
     savecore(8), shutdown(8), sync(8)


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