sccsdiff

The sccsdiff command determines (and prints on the standard output) the differences between any two versions of an SCCS file. The versions to be compared are specified with sccsdiff -r in the same way as with get -r. SID numbers must be specified as the first two arguments. The SCCS file or files to be processed are named last. Directory names and a lone hyphen are not acceptable to sccsdiff.

The following is an example of the format of sccsdiff:

   $ sccsdiff -r3.4 -r5.6 s.abc
