Chapter 19. The Revision Control System

This chapter presents the following topics:

As with SCCS in the preceding chapter, the Revision Control System (RCS) is designed to keep track of multiple file revisions, thereby reducing the amount of storage space needed. With RCS you can automatically store and retrieve revisions, merge or compare revisions, keep a complete history (or log) of changes, and identify revisions using symbolic keywords. RCS is believed to be more efficient than SCCS. Unlike SCCS, RCS preserves execute permission on the files it manages, and you can store binary data in RCS files.

RCS is not part of standard SVR4 or Solaris. It can be obtained from the Free Software Foundation (see http://www.gnu.org). This chapter describes RCS Version 5.7.

For more information, see Applying RCS and SCCS, listed in the Bibliography.
