reboot(1M)              (BSD Compatibility Package)              reboot(1M)

NAME
     reboot - restart the operating system

SYNOPSIS
     /usr/ucb/reboot [-dnq] [bootarguments]

DESCRIPTION
     reboot restarts the kernel. The kernel is loaded into memory by the
     PROM monitor, which transfers control to it.

     Although reboot can be run by the privileged user at any time,
     shutdown is normally used first to warn all users logged in of the
     impending loss of service. See shutdown(1M) for details.

     reboot performs a sync(1M) operation on the disks, and then a mul-
     tiuser reboot is initiated. See init(1M) for details.

     reboot normally logs the reboot to the system log daemon, syslogd(1M)
     and places a shutdown record in the login accounting file
     /var/adm/wtmp. These actions are inhibited if the -n or -q options are
     present.

OPTIONS
     -d   Dumps system core before rebooting. This option is provided for
          compatibility, but is not supported by the underlying reboot
          call.

     -n   Avoids the sync(1M). It can be used if a disk or the processor is
          on fire.

     -q   Quick. Reboots quickly and ungracefully, without first shutting
          down running processes.

     bootarguments
          These arguments are accepted for compatibility, but are ignored
          by reboot.

   Power Fail and Crash Recovery

     Normally, the system will reboot itself at power-up or after crashes.

FILES
     /var/adm/wtmp
          Login accounting file
