SYNOPSIS
/usr/sbin/reboot [-dlnq]
OPTIONS
Generates a crash dump of the system before halting it. Can be used
with any of the other options. Does not log the reboot using syslog
Does not sync the disks or log the reboot using syslog Performs a quick
reboot without first shutting down running processes; does not log the
reboot using syslog
DESCRIPTION
When the system is running and multiple users are logged in, use the
shutdown -r command to perform a reboot operation. If no users are
logged in, use the reboot command.
The reboot command normally stops all running processes, syncs the
disks, logs the reboot, and writes a shutdown entry in the login
accounting file, /var/adm/wtmp.
The reboot command uses the sync call to synchronize the disks, and to
perform other shutdown activities such as resynchronizing the hardware
time-of-day clock. After these activities, the system reboots. By
default, the system starts and the file systems are automatically
checked. If the start-up activities are successful, the system comes up
in the default run-level.
You must have root privileges to use this command.
Caution
Using the -n option can result in file system damage.
EXAMPLES
To enable the default reboot action, enter: reboot
This command causes the system to stop all running processes,
sync the disks, log the shutdown, and perform other routine
shutdown and reboot activities. To shut down the system without
logging the reboot, enter: reboot-l
This command shuts down the system and performs all shutdown and
reboot activities, except logging the shutdown. To reboot the
system abruptly, enter: reboot-q
This command reboots the system abruptly without shutting down
running processes.
