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 standard 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(1L).	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 default branch (normally the highest branch 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 co -j.  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  exe-
       cute

	       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 exe-
       cute 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.
