NAME

       reboot - restart the operating system

SYNOPSIS

       /usr/sbin/reboot [-dlnq] [boot_arguments]

       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.	On
       systems, reboot may also update the boot archive as needed to ensure a successful reboot.

       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 reboots itself at power-up or after crashes.

       The following options are supported:

       -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 calling sync(2) and do not log the reboot to syslogd(1M) or to /var/adm/wtmpx. The  kernel  still	attempts  to  sync
		       filesystems prior to reboot, except if the -d option is also present. If -d is used with -n, the kernel does not attempt to
		       sync filesystems.

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

       The following operands are supported:

       boot_arguments  An optional boot_arguments specifies arguments to the uadmin(2) function that are passed to the	boot  program  and  kernel
		       upon  restart.  The form and list of arguments is described in the boot(1M) and kernel(1M) man pages.. If the arguments are
		       specified, whitespace between them is replaced by single spaces unless the whitespace is  quoted  for  the  shell.  If  the
		       boot_arguments begin with a hyphen, they must be preceded by the -- delimiter (two hyphens) to denote the end of the reboot
		       argument list.

       Example 1: Passing the -r and -v Arguments to boot

       In the following example, the delimiter -- (two hyphens) must be used to separate the options of reboot from the arguments of boot(1M).

       example# reboot -dl -- -rv

       Example 2: Rebooting Using a Specific Disk and Kernel

       The following example reboots using a specific disk and kernel.

       example# reboot disk1 kernel.test/unix

       /var/adm/wtmpx	       login accounting file

       The  reboot  utility does not execute the scripts in /etc/rcnum.d or execute shutdown actions in inittab(4).  To ensure a complete shutdown
       of system services, use shutdown(1M) or init(1M) to reboot a Solaris system.
