RCSDIFF(1) RCSDIFF(1)

NAME
       rcsdiff - compare RCS revisions

SYNOPSIS
       rrccssddiiffff  [  -kksubst  ]  [ -qq ] [ -rrrev1 [ -rrrev2 ] ] [ -TT ] [ -VV[n] ] [
       -xxsuffixes ] [ -zzzone ] [ diff options ] file ...

DESCRIPTION
       rrccssddiiffff runs ddiiffff(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 ccii(1).

       The  option  -qq  suppresses diagnostic output.  Zero, one, or two revi-
       sions may be specified with -rr.  The  option  -kksubst  affects  keyword
       substitution  when  extracting  revisions,  as  described in ccoo(1); for
       example, -kkkk -rr11..11 -rr11..22 ignores differences  in  keyword  values  when
       comparing  revisions  11..11  and 11..22.  To avoid excess output from locker
       name substitution, -kkkkvvll is assumed if (1) at most one revision  option
       is  given,  (2)  no -kk option is given, (3) -kkkkvv is the default keyword
       substitution, and (4) the working file's  mode  would  be  produced  by
       ccoo -ll.   See ccoo(1) for details about -TT, -VV, -xx and -zz.  Otherwise, all
       options of ddiiffff(1) that apply to regular files are accepted,  with  the
       same meaning as for ddiiffff.

       If both rev1 and rev2 are omitted, rrccssddiiffff 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, rrccssddiiffff compares  revision  rev1
       of the RCS file with the contents of the corresponding working file.

       If  both  rev1  and rev2 are given, rrccssddiiffff compares revisions rev1 and
       rev2 of the RCS file.

       Both rev1 and rev2 may be given numerically or symbolically.

EEXXAAMMPPLLEE
       The command

               rrccssddiiffff  ff..cc

       compares the latest revision on the default branch of the RCS  file  to
       the contents of the working file ff..cc.

ENVIRONMENT       RRCCSSIINNIITT
              options  prepended  to  the  argument list, separated by spaces.
              See ccii(1) for details.

DIAGNOSTICS       Exit status is 0 for no differences during any comparison, 1  for  some
       differences, 2 for trouble.
