rc Command

Purpose

Performs normal startup initialization.

Syntax

rc

Description

The rc command has an entry in the /etc/inittab file. The init command creates a process for the rc command entry in the /etc/inittab file. The rc command performs normal startup initialization for the system. The contents of /etc/rc are installation specific. If all of the necessary operations complete successfully, the file exits with a zero return code that allows the init command to start loggers to complete normal initialization and startup.

Notes:

1. Many bringup functions such as activating page spaces and mounting filesystems are done by the rc command.
2. The root file system is implicitly mounted.
