rcsdiff(1)                                             rcsdiff(1)



     NAME
          rcsdiff - compare RCS revisions

     SYNOPSIS
          rcsdiff [-biwt] [-cefhn] [-rrev1] [-rrev2] files

     DESCRIPTION
          rcsdiff runs diff(1) to compare two revisions of each RCS
          file given.  A filename ending in ,v is an RCS filename,
          otherwise a working filename.  rcsdiff derives the working
          filename from the RCS filename and vice versa, as explained
          in co(1).  Pairs consisting of both an RCS and a working
          filename may also be specified.

          All options except -r have the same effect as described in
          diff(1).

          If both rev1 and rev2 are omitted, rcsdiff compares the la-
          test revision on the trunk with the contents of the
          corresponding working file.  This is useful for determining
          what was changed since the last checkin.

          If rev1 is given, but rev2 is omitted, rcsdiff compares re-
          vision 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

          runs diff on the latest trunk revision of RCS file f.c,v and
          the contents of working file f.c.
