sccsdiff
-r
sid1 -r
sid2 [options] filesReport differences between two versions of an SCCS file. sid1 and sid2 identify the deltas to be compared. This command invokes bdiff, which in turn calls diff. Solaris sccsdiff calls diff, not bdiff.
-p
Pipe output through pr.
-s
nUse file segment size n (n is passed to bdiff).
