Source code control system (SCCS)

Source Code Control System (SCCS) is a collection of UNIX system commands that maintain and track changes made to source code or documentation. SCCS is basically a file custodian. Under SCCS, whenever changes are made to a file, SCCS records those changes and maintains the original. SCCS can: These features are important if code and documentation undergo frequent changes due to maintenance or enhancement work. Whenever changes are applied to a file under SCCS control, only the latest set of changes are added to the SCCS image of that file. Using this approach, SCCS maintains successive versions, consuming minimal amounts of increased disk space. This allows for efficient use of resources and easy regeneration of previous file versions.
