reboot(1M)         UNIX System V(BSD Compatibility Package)          reboot(1M)


NAME
      reboot - restart the operating system

SYNOPSIS
      /usr/ucb/reboot [ -dnq ] [ boot arguments ]

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(1M) 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(1) operation on the disks, and then a multiuser
      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.

      The following options are available:

      -d    Dump system core before rebooting.  This option is provided for
            compatibility, but is not supported by the underlying reboot(3)
            call.

      -n    Avoid the sync(1).  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.

      boot arguments
            These arguments are accepted for compatibility, but are ignored by
            reboot.  See boot(1M) for details.

   Power Fail and Crash Recovery
      Normally, the system will reboot itself at power-up or after crashes.
