NAME

rcmgr, rc.config − Gets and sets run-time configuration variables stored in the files /etc/rc.config and /etc/rc.config.site

SYNOPSIS

/usr/sbin/rcmgr set variable value
/usr/sbin/rcmgr get variable

DESCRIPTION

The rcmgr command retrieves and sets run-time configuration variables stored in /etc/rc.config and /etc/rc.config.site.  These variables are used to configure various subsystems (for example, NFS or NTP) by scripts in the /sbin/init.d directory. 

FLAGS

set Sets the variable to value in the /etc/rc.config file. 

get Looks for variables in /etc/rc.config. If the variable is not found, the get operation looks for the variable in /etc/rc.config.site. This allows an administrator to use a common configuration in a local area network. The administrator can create and distribute a common /etc/rc.config.site file.  Node-specific information should stay in /etc/rc.config.  The get option allows a programmer to specify a default value for an option if it is not found in either the /etc/rc.config or the /etc/rc.config.local files. 

EXAMPLES

rcmgr set HOSTNAME yukio

This example sets the variable HOSTNAME to yukio in the /etc/rc.config file. 

rcmgr set IFCONFIG_0 111.111.1.11 netmask 255.255.252.0

This example sets the variable IFCONFIG_0 to "111.111.1.11 netmask 255.255.252.0" in the /etc/rc.config file. 

rcmgr get NIS_ARGS

This example displays the value the variable NIS_ARGS. If this variable is not set in the /etc/rc.config file, then the rcmgr command looks in the /etc/rc.config.site file for the variable. 

Startup scripts can use the get operation to provide values to variables as in the following examples:

host=‘rcmgr get HOSTNAME‘

This example sets the value of host to the value of HOSTNAME in the /etc/rc.config file. 

num_nfsd=‘rcmgr get NUM_NFSD 4‘

This example sets num_nfsd to 4 if NUM_NFSD does not exist in the /etc/rc.config file or in the /etc/rc.config.site file. 

FILES

/etc/rc.config
/etc/rc.config.site
