NAME
       rcsdiff - compare RCS revisions

SYNOPSIS
       rcsdiff	[  -ksubst  ]  [ -q ] [	-rrev1 [ -rrev2	] ] [ -T ] [ -V[n] ] [
       -xsuffixes ] [ -zzone ] [ 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 revi-
       sions may be specified with -r.	The  option  -ksubst  affects  keyword
       substitution  when extracting revisions,	as described in	co(1); for ex-
       ample, -kk -r1.1	-r1.2 ignores differences in keyword values when  com-
       paring  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 sub-
       stitution, and (4) the working file's mode would	be produced by	co -l.
       See  co(1) for details about -T,	-V, -x and -z.	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.

EXAMPLE
       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
       RCSINIT
	      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.
