- NAME
- rcsmerge - merge RCS revisions
-
- SYNOPSIS
- rcsmerge [options] file
-
- DESCRIPTION
- 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.
-
- 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
- checked-out revision.
-
- OPTIONS
- -ksubst
- 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.
-
- -p[rev]
- Send the result to standard output instead of
- overwriting the working file.
-
- -q[rev]
- Run quietly; do not print diagnostics.
-
- -r[rev]
- Merge with respect to revision rev. Here an empty rev
- stands for the latest revision on the default branch,
- normally the head.
-
- -Vn Emulate RCS version n. See co(1) for details.
-
- -xsuffixes
- Use suffixes to characterize RCS files. See ci(1) for
- details.
-
- EXAMPLES
- 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 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.
-
- ENVIRONMENT
- RCSINIT
- options prepended to the argument list, separated by
- spaces. See ci(1) for details.
-
- DIAGNOSTICS
- Exit status is 0 for no overlaps, 1 for some overlaps, 2 for
- trouble.
