NAME

halt, reboot - stop the system.

SYNOPSIS

/sbin/halt [-n] [-w] [-d] [-f]
/sbin/reboot [-n] [-w] [-d] [-f]

DESCRIPTION

Halt notes that the system is being brought down in the file /var/log/wtmp, and then either tells the kernel to halt or reboot the system. If halt or reboot is called when the system is not in runlevel 0 or 6, shutdown(8) will be invoked instead (with the flag -h or -r).

OPTIONS

-n
Don't sync before reboot or halt.
-w
Don't actually reboot or halt but only write the wtmp record (in the /var/log/wtmp file).
-d
Don't write the wtmp record. The -n flag implies -d.
-f
Force halt or reboot, don't call shutdown.

DIAGNOSTICS

If you're not the superuser, you will get the message `must be superuser'.

NOTES

Under previous sysvinit releases, reboot and halt should never be called directly. From this release on halt and reboot invoke shutdown if the system is in runlevel 1-5.
