RCSDIFF(1)                                                                                        RCSDIFF(1)



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 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 -T, -V, -x and -z.  Oth-erwise, Otherwise,
       erwise, 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 determin-ing determining
       ing 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  con-tents contents
       tents 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.
