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

NAME

       halt - abruptly stop the system

SYNOPSIS

       halt [-f]

DESCRIPTION

       Halt  stops  the  system  almost immediately.  The users are not informed about the things to come.  Halt is logged in /usr/adm/wtmp and in
       /usr/adm/authlog, if these files exist.	Halt should only be run by the super-user, any other caller will be refused.

       Halt is a rather rude program.  Shutdown(8) is preferred for it performs a more gentle halt routine.

       Halt -f is even worse, it omits the terminate signals that are normally sent first to all processes to give them a  chance  to  die  peace-
       fully.

SEE ALSO

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