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.  Otherwise 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.
