rcsmerge - merge RCS revisions
rcsmerge [options] file
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 revi-
sions may be specified. If only one revision is speci-
fied, 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 sym-
rcsmerge 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
-A Output conflicts using the -A style of diff3(1), if
supported by diff3. This merges all changes lead-
ing from file2 to file3 into file1, and generates
the most verbose output.
-E, -e These options specify conflict styles that generate
less information than -A. See diff3(1) for
details. The default is -E. With -e, rcsmerge
does not warn about conflicts.
Use subst style keyword substitution. See co(1)
for details. For example, -kk -r1.1 -r1.2 ignores
differences in keyword values when merging the
changes from 1.1 to 1.2. It normally does not make
sense to merge binary files as if they were text,
so rcsmerge refuses to merge files if -kb expansion
Send the result to standard output instead of over-
writing the working file.
Run quietly; do not print diagnostics.

Merge with respect to revision rev. Here an empty
rev stands for the latest revision on the default
branch, normally the head.
-T This option has no effect; it is present for com-
patibility with other RCS commands.
-V Print RCS's version number.
-Vn Emulate RCS version n. See co(1) for details.
Use suffixes to characterize RCS files. See ci(1)
-zzone Use zone as the time zone for keyword substitution.
See co(1) for details.
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 -r3.4 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 22.214.171.124 and execute co -j:
ci -r126.96.36.199 f.c
co -r3.4 -j2.8:188.8.131.52 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
options prepended to the argument list, separated
by spaces. See ci(1) for details.
Exit status is 0 for no overlaps, 1 for some overlaps, 2
