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 and exe- cute co -j: ci -r2.8.1.1 f.c co -r3.4 -j2.8: 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.

rcsdiff - compare RCS revisions SYNOPSIS
rcsdiff [-ksubst] [-q] [-rrev1 [-rrev2]] [-Vn] [-xsuffixes] [diff options] file... DESCRIPTION
rcsdiff runs diff(1) to compare two revisions of each RCS file given. Pathnames matching an RCS suffix denote RCS files; all others denote working files. Names are paired as explained in ci(1). The option -q suppresses diagnostic output. Zero, one, or two revisions may be specified with -r. The option -ksubst affects keyword sub- stitution when extracting revisions, as described in co(1); for example, -kk -r1.1 -r1.2 ignores differences in keyword values when compar- ing revisions 1.1 and 1.2. To avoid excess output from locker name substitution, -kkvl is assumed if (1) at most one revision option is given, (2) no -k option is given, (3) -kkv is the default keyword substitution, and (4) the working file's mode would be produced by co -l. See co(1) for details about -V and -x. Otherwise, all options of diff(1) that apply to regular files are accepted, with the same meaning as for diff. If both rev1 and rev2 are omitted, rcsdiff compares the latest revision on the default branch (by default the trunk) with the contents of the corresponding working file. This is useful for determining what you changed since the last checkin. If rev1 is given, but rev2 is omitted, rcsdiff compares revision rev1 of the RCS file with the contents of the corresponding working file. If both rev1 and rev2 are given, rcsdiff compares revisions rev1 and rev2 of the RCS file. Both rev1 and rev2 may be given numerically or symbolically. EXAMPLES
The command rcsdiff f.c compares the latest revision on the default branch of the RCS file to the contents of the working file f.c. ENVIRONMENT
options prepended to the argument list, separated by spaces. See ci(1) for details. DIAGNOSTICS
Exit status is 0 for no differences during any comparison, 1 for some differences, 2 for trouble. IDENTIFICATION
