RCSMERGE(1)                                           RCSMERGE(1)



     NAME
          rcsmerge - merge RCS revisions

     SYNOPSIS
          rcsmerge -rrev1 [ -rrev2 ] [ -p ] file

     DESCRIPTION
          rcsmerge incorporates the changes between rev1 and rev2 of
          an RCS file into the corresponding working file. If -p is
          given, the result is printed on the std. output, otherwise
          the result overwrites the working file.

          A file name ending in ',v' is an RCS file name, otherwise a
          working file name. merge derives the working file name from
          the RCS file name and vice versa, as explained in co(1). A
          pair consisting of both an RCS and a working file name may
          also be specified.

          rev1 may not be omitted. If rev2 is omitted, the latest
          revision on the trunk is assumed.  Both rev1 and rev2 may be
          given numerically or symbolically.

          rcsmerge prints a warning if there are overlaps, and
          delimits the overlapping regions as explained in the -j
          version of co.  The command is useful for incorporating
          changes into a checked-out revision.

     EXAMPLES
          Suppose you have released revision 2.8 of f.c. Assume
          furthermore that you just completed revision 3.4, when you
          receive updates to release 2.8 from someone else.  To
          combine the updates to 2.8 and your changes between 2.8 and
          3.4, put the updates to 2.8 into file f.c and execute

                  rcsmerge  -p  -r2.8  -r3.4  f.c  >f.merged.c

          Then examine f.merged.c.  Alternatively, if you want to save
          the updates to 2.8 in the RCS file, check them in as
          revision 2.8.1.1 and execute co -j:

                  ci  -r2.8.1.1  f.c
                  co  -r3.4  -j2.8:2.8.1.1  f.c

          As another example, the following command undoes the changes
          between revision 2.4 and 2.8 in your currently checked out
          revision in f.c.

                  rcsmerge  -r2.8  -r2.4  f.c

          Note the order of the arguments, and that f.c will be
          overwritten.
