Editing Source Code Control System (section)

==SCCS basic commands==
SCCS provides a set of commands in the form of macro invocations that perform or initiate source code management functions with a simple syntax, such as create, get, edit, prt.<ref>[http://sccs.sourceforge.net/man/sccs.me.html  An Introduction to the Source Code Control System ] Eric Allman, Project Ingres, University of California at Berkeley</ref><ref>[http://docs.oracle.com/cd/E19504-01/802-5880/6i9k05dhp/index.html  Source Code Control System] Programming Utilities Guide</ref> It also provides access to the revision history of files under management. These commands are implemented as argument verbs to the driver program ''sccs''.

=== Create ===
The sccs command ''create'' uses the text of a source file to create a new history file. For example:
<syntaxhighlight lang="console">
$ sccs create program.c
program.c:
1.1
87 lines
</syntaxhighlight>
The outputs are name, version and lines.

The command is a macro that expands to ''admin'' to create the new history file followed by ''get'' to retrieve the file.

=== Edit ===
<syntaxhighlight lang="console">
$ sccs edit program.c
1.1
new delta 1.2
87 lines
</syntaxhighlight>
Edit a specific file.

The command is a macro that expands to ''get -e''.

=== Delget ===
<syntaxhighlight lang="console">
$ sccs delget program.c
comments? main function enhanced
1.2
10 inserted
0 deleted
87 unchanged
1.2
97 lines
</syntaxhighlight>
Check in new version and get the new version from sccs.

The command is a macro that expands to ''delta'' to check in the new version file followed by ''get'' to retrieve the file.

=== Get ===
<syntaxhighlight lang="console">
$ sccs get program.c
1.1
87 lines
</syntaxhighlight>
The outputs are version and lines you want to get from specific file.

=== Prt ===
<syntaxhighlight lang="console">
$ sccs prt program.c
</syntaxhighlight>
This command produces a report of source code changes.
