Man Pages - Manpage for reboot
Posted May 26th, 2004 in Man Pages (Updated June 15th, 2004)
man page for the unix linux bsd command reboot
NAME
halt, reboot, poweroff, suspend - stop the system.
SYNOPSIS
/sbin/halt [-n] [-w] [-d] [-f] [-i] [-p]
/sbin/reboot [-n] [-w] [-d] [-f] [-i]
/sbin/poweroff [-n] [-w] [-d] [-f] [-i]
/sbin/swsusp [-w] [-d]
DESCRIPTION
Halt notes that the system is being brought down in the file /var/log/wtmp, and then either tells the kernel to halt, reboot, poweroff or suspend 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(8).
-i Shut down all network interfaces just before halt or reboot.
-p When halting the system, do a poweroff. This is the default when halt is called as poweroff.
DIAGNOSTICS
If you're not the superuser, you will get the message `must be superuser'.
NOTES
Under older sysvinit releases , reboot and halt should never be called directly. From release 2.74 on halt and reboot invoke shutdown(8) if the system is not in runlevel 0 or 6. This means that if halt or reboot cannot find out the current runlevel (for example, when /var/run/utmp hasn't been initialized correctly) shutdown will be called, which might not be what you want. Use the -f flag if you want to do a hard halt or reboot.
