The SCCS (Source Code Control System) command in IBM’s mainframe operating system, z/OS, is used to manage and track changes to source code files. It is a version control system that allows multiple users to work on a codebase simultaneously while providing a way to track and revert changes.
Here are a few examples of how to use the SCCS command:
- Check out a file for editing:
sccs get file.c
- Check in a file after editing:
sccs delta file.c
- Show the history of a file:
sccs prs -l file.c
- Show the differences between two versions of a file:
sccs diffs -r1.2 file.c
- Undo changes made to a file:
sccs unget -r1.2 file.c
- Create a new SCCS file
sccs create file.c
Note that the SCCS command is specific to IBM’s mainframe operating system, z/OS, and may not be available on other operating systems.
