reboot

reboot [options]

System administration command. Close out filesystems, shut down the system, then reboot. Because this command immediately stops all processes, it should be run only in single-user mode. If the system is not in runlevel 0 or 6, reboot calls shutdown -r.

Options

-d

Suppress writing to /var/log/wtmp.

-f

Call reboot even when shutdown would normally be called.

-i

Shut down network interfaces before reboot.

-n

Suppress normal call to sync.

-w

Suppress normal execution; simply write to /var/log/wtmp.
