NAME    [Toc]    [Back]

       halt - Stops the processor

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/halt [-d] [-l] [-n] [-q] [-y]

OPTIONS    [Toc]    [Back]

       Generates  a  crash  dump of the system before halting it.
       Can be used with any other option.  Does not log the  halt
       using syslog.  Prevents the sync before stopping, and does
       not log the halt using syslog.  Causes a quick halt,  does
       not  log  the  halt  using syslog, and makes no attempt to
       kill all processes.  Halts the system from a dial-up operation.

DESCRIPTION    [Toc]    [Back]

       If  other users are logged into the system, or if the system
 is  operating  at  a  multiuser  run  level,  use  the
       /usr/sbin/shutdown -h command to halt the system.  If only
       the root user is logged in, and you do not plan to restart
       the system immediately, use the halt command.

       The  halt  command writes data to the disks and then stops
       the processor(s), but does not reboot the machine.

       You must be the root user to run this command.

       When the system displays the message,  you  can  turn  off
       power to the machine.

       If  the  command  is  invoked  without  the  -l, -n, or -q
       option, the halt program logs the shutdown using the  syslogd
  command  and  places a record of the shutdown in the
       login accounting file, /var/adm/wtmp.  Using  the  -q  and
       the -n options imply the -l option.

EXAMPLES    [Toc]    [Back]

       To halt the system without logging the shutdown in the log
       file, enter: halt -l To halt the  system  quickly,  enter:
       halt  -q  To halt the system quickly, also leaving a crash
       dump for the savecore command, enter: halt -d -q  To  halt
       the system from a dial-up, enter: halt -y
