(BSD System Compatibility)
reboot(1Mbsd)
reboot --
(BSD) restart the operating system
Synopsis
/usr/ucb/reboot [-dlnq] [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(1M)
operation on the disks, and then a multiuser reboot is initiated.
See
init(1M)
for details.
Executing reboot -l
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.
Command options
-d-
Dump system core before rebooting.
This option is provided for compatibility, but is not
supported by the underlying
reboot(3bsd)
call.
-l-
Logs a message to the system log indicating who rebooted the system.
-n-
Avoid 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.
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.
Files
/var/adm/wtmp-
login accounting file
