reboot(1M)		System Administration Commands		    reboot(1M)

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 mem-
       ory 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 reboots 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 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.

OPERANDS
	boot_arguments
	     An	optional boot_arguments	string can be used  to	specify	 argu-
	     ments  to	the uadmin(2) function that will be 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	multi-
	     ple arguments are specified, they must be quoted for  the	shell,
	     as	 shown	in  the	 EXAMPLES section. If the boot_arguments begin
	     with a hyphen, they must be preceded by the -- delimiter (two hy-
	     phens) to denote the end of the reboot argument list.

EXAMPLES
       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.  Note
       that multiple boot arguments are	quoted.

       example#	reboot "disk1 kernel.test/unix"

FILES
       /var/adm/wtmpx
	     login accounting file

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