Merge with respect to revision

on the default branch, normally the head.

to characterize RCS
rcsmerge incorporates the changes between two revisions of an RCS file into the corresponding working file.
Pathnames matching an RCS suffix denote RCS files; all others denote working files. Names are paired as explained in ci(1).
At least one revision must be specified with one of the options described below, usually -r. At most two revisions may be specified. If only one revision is specified, the latest revision on the default branch (normally the highest branch on the trunk) is assumed for the second revision. Revisions may be specified numerically or symbolically.
prints a warning if there are overlaps,
and delimits the overlapping regions as explained in
merge(1). The command
is useful for incorporating changes into a checked-out revision.
Suppose you have released revision 2.8 of f.c. Assume furthermore that after you complete an unreleased revision 3.4, 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 -r3.4f.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 220.127.116.11 and execute co -j: ci -r18.104.22.168 f.c co -r3.4 -j2.8:22.214.171.124 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
options prepended to the argument list, separated by spaces.
Exit status is 0 for no overlaps, 1 for some overlaps, 2 for trouble.
