NAME
       sccsdiff - compare two versions of an SCCS file

SYNOPSIS
       sccsdiff -rSID1 -rSID2 [-p] [-sn] files

DESCRIPTION
       Sccsdiff compares two versions of an SCCS file and generates the
       differences between them.  Any number of SCCS files may be specified,
       but arguments apply to all files.

            -rSID?      SID1 and SID2 specify the deltas of an SCCS file
                        that are to be compared.  Versions are passed to
                        bdiff(1) in the order given.

            -p          Pipe output for each file through pr(1).

            -sn         N is the file segment size that bdiff will pass to
                        diff(1).  This is useful when diff fails due to a
                        high system load.

EXAMPLES
       sccsdiff -r1.3 -r1.4 /work/archives/s.file1

       This command lists differences (if there are any) between versions
       '1.3' and '1.4' of the SCCS file 's.file1'.  If the versions are
       identical, you will get the message 's.file1: No differences'.

       sccsdiff -r1.3 -r1.4 -p s.file2

       This command does the same as the previous example, except the output
       is formatted.

       sccsdiff -r1.5.1.1 -r1.5.1.2 -s100 s.file3

       This command lists any differences between versions '1.5.1.1' and
       '1.5.1.2' of the SCCS file 's.file3'.  The -s100 will pass 100
       segments at a time from 'bdiff' to 'diff'.  This is useful under high
       system load.

FILES
       /tmp/get?????  Temporary files

DIAGNOSTICS
       You get the message

              file: No differences

       if the two versions are the same.

       Use help(1) for explanations.

       Exit code is 0 on successful completion, and >0 if an error occurs.
