NAME
     reboot - restart the operating system

SYNOPSIS
     /usr/sbin/reboot [ -dlnq ]  [  boot  arguments  ]

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

     Although reboot can be run by the super-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.

     The reboot utility performs  a  sync(1M)  operation  on  the
     disks,  and  then  a  multi-user  reboot  is  initiated. See
     init(1M) for details.

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

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

OPTIONS
     -d    Force  a  system  crash  dump  before  rebooting.  See
           dumpadm(1M)  for  information  on  configuring  system
           crash dumps.

     -l    Suppress sending a message to the system  log  daemon,
           syslogd(1M) about who executed  reboot.

     -n    Avoid the sync(1M) operation.
            Use of this option can cause file system damage.

     -q    Quick. Reboot quickly and ungracefully, without  shut-
           ting down running processes first.

      bootarguments
           These arguments are accepted  for  compatibility,  and
           are passed unchanged to the uadmin(2) function.

EXAMPLES
     Example 1: Example of the reboot utility.

     In the example below, the delimiter `--' (two hyphens)  must
     be  used  to  separate the options of  reboot from the argu-
     ments of  boot(1M).
