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:
store text files
retrieve specific versions of files
control updating access to files
identify the version of a retrieved file
record when, why and by whom changes are made to a file
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.
