reboot - Restarts the machine
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
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.
Using the -n option can result in file system damage.
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:
This command reboots the system abruptly without
shutting down running processes.
