RC(8)

NAME
rc - command script for auto-reboot and daemons

SYNOPSIS
rc
rc.local

DESCRIPTION
Rc is the command script which controls the automatic reboot and rc.local is the script holding commands which are pertinent only to a specific site.

When an automatic reboot is in progress, rc is invoked with the argument autoboot. The first portion of rc runs an fsck(8) with option -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 rc is run.

The second part of rc, which is run after an auto-reboot succeeds and also if rc is invoked when a single user shell terminates (see init(8)), starts all the daemons on the system, preserves editor files and clears the scratch directory /tmp.

Rc.local is executed immediately before any other commands after a successful fsck. Normally, the first commands placed in the rc.local file define the machine's name, using hostname(1), and save any possible core image that might have been generated as a result of a system crash, with savecore(8). The latter command is included in the rc.local file because the directory in which core dumps are saved is usually site specific.

Following tradition, the startup files rc and rc.local reside in /etc.
