RCS

RCS is the abbreviation of revision control system, which is efficient and easy to use. This article, taking ArchLinux for example, aims to illustrate how to install and use it.

Above all, for ArchLinux, RCS can be easily installed by running

pacman -S rcs

Then it can be used immediately without further configuration. The usage can be listed as follows:

• ci -u FILENAME: check in or intialize the file FILENAME;
• co -l FILENAME: check out FILENAME and lock it;
• rlog FILENAME: display the log of changes for FILENAME;
• rcdiff FILENAME: compare FILENAME of different versions;
• rcs -u FILENAME: override the locked FILENAME.
