# reboot(8)

## NAME

         reboot - reboot the system immediately

## SYNOPSIS

         reboot [-f]

## DESCRIPTION

         Reboot can be used to reboot the system after installing  a  new  kernel.
         It  does not inform the users, but does log it's actions in /usr/adm/wtmp
         and /usr/adm/authlog.  The system is then  rebooted  with  the  reboot(2)
         systemcall.

         If the -f flag is not given then all processes are sent terminate signals
         to give them a chance to die peacefully before the reboot() call.

         If the wtmp file exists, reboot logs itself as if  it  were  a  shutdown.
         This  is  done  to  prevent  last(1)  from  talking about system-crashes.
         Reboot is registered as is in the authlog file.

         Reboot can only be executed by the super-user.  Any other caller will  be
         refused, either by reboot(8) or by reboot(2).

## SEE ALSO

         reboot(2), shutdown(8), halt(8), boot(8).

## BUGS

         The error message's given by reboot are not  always  useful.   There  are
         several routines that can fail, but which are not fatal for the program.
