RCSDIFF(1)              FreeBSD General Commands Manual             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.  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.
