.Sh NAME
|
||||
.Nm halt
|
||||
.Nd stop the processor
|
||||
.Sh SYNOPSIS
|
||||
.Nm halt
|
||||
.Op Fl n
|
||||
.Op Fl q
|
||||
.Op Fl y
|
||||
.Sh DESCRIPTION
|
||||
.Nm Halt
|
||||
writes out sandbagged information to the disks and then stops
|
||||
the processor. The machine does not reboot, even if the auto-reboot
|
||||
switch is set on the console.
|
||||
.Pp
|
||||
Available options for
|
||||
.Nm halt :
|
||||
.Bl -tag -width Ds
|
||||
.It Fl n
|
||||
No sync before stopping.
|
||||
.It Fl q
|
||||
Quick halt, no graceful shutdown is attempted.
|
||||
.It Fl y
|
||||
This option is needed if you are trying to halt the system from a dialup.
|
||||
.El
|
||||
.Pp
|
||||
.Nm Halt
|
||||
normally logs the shutdown using
|
||||
.Xr syslog 8
|
||||
and places a shutdown record in the login accounting file
|
||||
.Pa /var/log/wtmp.
|
||||
These actions are inhibited if the
|
||||
.Fl n
|
||||
or
|
||||
.Fl q
|
||||
options are present.
|
||||
.Sh SEE ALSO
|
||||
.Xr reboot 8 ,
|
||||
.Xr shutdown 8 ,
|
||||
.Xr syslogd 8
|
||||
.Sh BUGS
|
||||
It is very difficult to halt a
|
||||
.Tn VAX ,
|
||||
as the machine wants to then
|
||||
reboot itself. A rather tight loop suffices.
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
command appeared in
|
||||
.Bx 4.0 .
