RCSDIFF(1)          UNIX Programmer's 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 oth-
     ers 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 substitu-
     tion, -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 reg-
     ular 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.
