NAME
  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 substitution when
  extracting revisions, as described in co(1); for example, -kk -r1.1 -r1.2
  ignores differences in keyword values when comparing 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
  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.
