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/log,  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 peacefully.


SEE ALSO

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