use RCS to manage system configuration files rather than git/svn etc.
use RCS to manage system configuration files rather than git/svn etc.
This quick tutorial will teach you everything you need to know to use the Revision Control System (RCS) for system administration. RCS is useful for applying version control to all of your system files. It has considerably more functionality than we’ll discuss here, so be sure to take a look at the manual pages and the references at the end of this appendix if you plan to use it heavily. You may also be wondering why we’re bothering with RCS when more modern systems, such as Git and Subversion, exist. That’s a good question, and I’ll address it at the end of the tutorial. In the meantime, though, let’s get the RCS basics down; they’ll help with the explanation later.
