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


NAME

     reboot, halt - stopping and restarting the system


SYNOPSIS

     halt [-nqd]
     reboot [-nqd]


DESCRIPTION

     The halt and reboot utilities flush the file system cache to disk, 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:

     -n      If the -n option is specified, the file system 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 file sys-
             tem cache is performed.  This option should probably not be used.

     -d      If the -d option is specified, the system will create a dump be-
             fore rebooting.  This option is useful for debugging system dump
             procedures or capturing the state of a corrupted or misbehaving
             system.

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