RCSMERGE(1)		     General Commands Manual		     RCSMERGE(1)

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 work-
     ing 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.  Revi-
     sions may be specified numerically or symbolically.

     rcsmerge  prints a warning if there are overlaps, and delimits the overlap-
     ping regions as explained in merge(1).  The command is useful for	incorpo-
     rating changes into a checked-out revision.

OPTIONS
     -A     Output  conflicts  using  the  -A style of diff3(1), if supported by
	    diff3.  This merges all changes leading 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.

     -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.   It  normally  does  not  make
	    sense  to  merge  binary files as if they were text, so rcsmerge re-
	    fuses to merge files if -kb expansion is used.

     -p[rev]
	    Send the result to standard output instead of overwriting the  work-
	    ing 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.

     -T     This option has no effect; it  is  present	for  compatibility  with
	    other RCS commands.

     -V     Print RCS's version number.

     -Vn    Emulate RCS version n.  See co(1) for details.

     -xsuffixes
	    Use suffixes to characterize RCS files.  See ci(1) for details.

     -zzone
	    Use  zone  as the time zone for keyword substitution.  See co(1) for
	    details.

EXAMPLES
     Suppose you have released revision 2.8 of f.c.  Assume furthermore that af-
     ter 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  be-
     tween 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 revi-
     sion 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.
