halt(1M)                         DG/UX R4.11                        halt(1M)


NAME
       halt - stop the system processor

SYNOPSIS
       /sbin/halt [ -lnqy ]
       /sbin/halt [ -l ] -p [ string ]
       /sbin/halt [ -l ] -P [ string ]

DESCRIPTION
       Halt writes out any information pending to the disks and then stops
       the processor.

       Halt normally logs the system shutdown to the system log daemon,
       syslogd(1M), and places a shutdown record in the login accounting
       file /etc/wtmp.  These actions are inhibited if the -n or -q options
       are present.

       Options are:

       -l     Do not log the system shutdown to syslogd.

       -n     Prevent the sync before stopping.

       -q     Quick halt.  No graceful shutdown is attempted.

       -y     Halt the system, even from a dialup terminal.

       -p     Execute a user requested system halt, and enter the kernel
              debugger during the halt (if it is linked in).  The optional
              string will be displayed when the halt occurs.

       -P     Execute a user requested system halt, but do not enter the
              kernel debugger during the halt.  The optional string will be
              displayed when the halt occurs.

FILES
       /etc/wtmp           login accounting file
