Introduction to GNC

Note: this page assumes knowledge of the GNC script process and it's commands and parameters. Please have a full understanding of the Groovix NetCustomization page before continuing.

Starting a new GNC Script using the GNC template

When you are ready to make your own GNC update, run the following command in an xterm window to create a copy of the gnc template: cp -rp var/www/groovix/gnc/doc/template/[updatename] where [updatename] is the name of your update.

Introduction to the gncget command

The directory structure inside each GNC update should be treated as if it is the / (root) directory. When the gncget command is used, it copies and replaces files in the GNC update directory in the same directories as the actual / (root) directory. For example, to replace the /etc/network/interfaces file on a machine, create the interfaces file in a etc/network/ directory under your update directory and use the gncget command gncget /etc/network/interfaces.

Introduction to the apt-get install and apt-get remove commands
