Table of Contentshalt, reboot - stop the system. /sbin/halt [-n] [-w] [-d] [-f]
/sbin/reboot [-n] [-w] [-d] [-f] 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). - -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.
If you're not the superuser, you will get the message `must be superuser'. 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. Miquel van Smoorenburg, miquels@drinkel.ow.org shutdown(8), init(1).
