reboot(8)		    System Manager's Manual		     reboot(8)



NAME
       reboot, halt, poweroff - reboot or stop the system

SYNOPSIS
       reboot [OPTION]...

       halt [OPTION]...

       poweroff [OPTION]...

DESCRIPTION
       These programs allow a system administrator to reboot, halt or poweroff
       the system.

       When called with --force or when in runlevel 0 or 6, this tool  invokes
       the reboot(2) system call itself and directly reboots the system.  Oth-
       erwise this simply invokes the shutdown(8) tool	with  the  appropriate
       arguments.

       Before  invoking	 reboot(2), a shutdown time record is first written to
       /var/log/wtmp

OPTIONS
       -f, --force
	      Does not invoke shutdown(8)  and	instead	 performs  the	actual
	      action you would expect from the name.

       -p, --poweroff
	      Instructs the halt command to instead behave as poweroff.

       -w, --wtmp-only
	      Does  not	 call  shutdown(8)  or	the  reboot(2) system call and
	      instead only writes the shutdown record to /var/log/wtmp

       --verbose
	      Outputs slightly more verbose messages  when  rebooting,	useful
	      for debugging problems with shutdown.

ENVIRONMENT
       RUNLEVEL
	      reboot  will  read  the  current	runlevel from this environment
	      variable if set in preference to reading from /var/run/utmp

FILES
       /var/run/utmp
	      Where the current runlevel will be read  from;  this  file  will
	      also  be	updated	 with  the runlevel record being replaced by a
	      shutdown time record.

       /var/log/wtmp
	      A new runlevel record for the shutdown time will be appended  to
	      this file.
