.Sh NAME
|
||
|
|
.Nm rc
|
||
|
|
.Nd command script for auto\-reboot and daemons
|
||
|
|
.Sh SYNOPSIS
|
||
|
|
.Nm rc
|
||
|
|
.Nm rc.local
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
.Nm Rc
|
||
|
|
is the command script which controls the automatic reboot and
|
||
|
|
.Nm rc.local
|
||
|
|
is the script holding commands which are pertinent only
|
||
|
|
to a specific site.
|
||
|
|
.Pp
|
||
|
|
When an automatic reboot is in progress,
|
||
|
|
.Nm rc
|
||
|
|
is invoked with the argument
|
||
|
|
.Em autoboot .
|
||
|
|
The first portion of
|
||
|
|
.Nm rc
|
||
|
|
runs an
|
||
|
|
.Xr fsck 8
|
||
|
|
with option
|
||
|
|
.Fl p
|
||
|
|
to ``preen'' all the disks of minor inconsistencies resulting
|
||
|
|
from the last system shutdown and to check for serious inconsistencies
|
||
|
|
caused by hardware or software failure.
|
||
|
|
If this auto-check and repair succeeds, then the second part of
|
||
|
|
.Nm rc
|
||
|
|
is run.
|
||
|
|
.Pp
|
||
|
|
The second part of
|
||
|
|
.Nm rc ,
|
||
|
|
which is run after a auto-reboot succeeds and also if
|
||
|
|
.Nm rc
|
||
|
|
is invoked when a single user shell terminates (see
|
||
|
|
.Xr init 8 ) ,
|
||
|
|
starts all the daemons on the system, preserves editor files
|
||
|
|
and clears the scratch directory
|
||
|
|
.Pa /tmp .
|
||
|
|
.Pp
|
||
|
|
.Nm Rc.local
|
||
|
|
is executed immediately before any other commands after a successful
|
||
|
|
.Xr fsck .
|
||
|
|
Normally, the first commands placed in the
|
||
|
|
.Nm rc.local
|
||
|
|
file define the machine's name, using
|
||
|
|
.Xr hostname 1 ,
|
||
|
|
and save any possible core image that might have been
|
||
|
|
generated as a result of a system crash, with
|
||
|
|
.Xr savecore 8 .
|
||
|
|
The latter command is included in the
|
||
|
|
.Nm rc.local
|
||
|
|
file because the directory in which core dumps are saved
|
||
|
|
is usually site specific.
|
||
|
|
.Pp
|
||
|
|
Following tradition, the startup files
|
||
|
|
.Nm rc
|
||
|
|
and
|
||
|
|
.Nm rc.local
|
||
|
|
reside in
|
||
|
|
.Pa /etc .
