Using SCCS

The Solaris 7 operating environment source code control system (SCCS) is slightly different from the SunOS release 4.x version. The same set of commands and subcommands are supported in both environments. SCCS directories and s.files used on SunOS release 4.x systems work equally well on Solaris 7 systems.

In the SunOS release 4.x software, the SCCS commands were located in the /usr/sccs directory. These commands are located with the other programming tools in /usr/ccs/bin in the Solaris 7 operating environment.

One difference between SunOS release 4.x and Solaris 7 utilities is the handling of unreadable s.files. The SunOS release 4.x commands print an error and continue when they encounter an unreadable s.file. The Solaris 7 commands silently ignore the error.
