RCSMERGE(1-SysV)    RISC/os Reference Manual     RCSMERGE(1-SysV)



NAME
     rcsmerge - merge RCS revisions

SYNOPSIS
     rcsmerge -rrev1 [ -rrev2 ] [ -p ] [file] 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 delim-
     its the overlapping regions as explained in co -j.  The com-
     mand is useful for incorporating changes into a checked-out
     revision.

EXAMPLES
     Suppose you have released revision 2.8 of f.c. Assume furth-
     ermore that you just completed revision 3.4, when you
     receive updates to release 2.8 from someone else.  To com-
     bine 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 revi-
     sion 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.
