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 by syslog(3) (level auth.notice).  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 can only be executed by the super-user.  Any other caller will  be
     refused, either by reboot(8) or by reboot(2).
