 NAME    [Toc]    [Back]
      rcsdiff - compareRCS revisions

 SYNOPSIS    [Toc]    [Back]
      rcsdiff [-bcefhn] [-rrev1] [-rrev2] file ...

 DESCRIPTION    [Toc]    [Back]
      rcsdiff compares two revisions of each given RCS file and creates
      output very similar to diff (see diff(1)).  A file name ending in ,v
      is an RCS file name, otherwise it is a working file name.  rcsdiff
      derives the working file name from the RCS file name and vice versa,
      as explained in rcsintro(5).  Pairs consisting of both an RCS and a
      working file name can also be specified.

      rcsdiff recognizes the following options:

           -b    Same as described in diff(1);

           -e    Same as described in diff(1);

           -f    Same as described in diff(1);

           -h    Same as described in diff(1);

           -n    Generate an edit script of the format used by RCS.

           -c[n] Generate a diff with lines of context.  The default is to
                 present 3 lines of context.  To change, specify n; for
                 example, -c10 gives 10 lines of context.

                 -c modifies the output format slightly from the normal
                 diff(1) output.  The ``context'' output begins with
                 identification of the files involved and their creation
                 dates, then each change is separated by a line with a dozen
                 * (asterisks).  Lines removed from file1 are marked with -
                 (dashes); those added to file2 with + (pluses).  Lines that
                 are changed from one file to the other are marked in both
                 files with ! (exclamation marks).

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

      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 can be given numerically or symbolically.

 EXAMPLES    [Toc]    [Back]
      Compare the latest trunk revision of RCS file f.c,v and the contents
      of working file f.c:

           rcsdiff f.c

      Compare the revisions 1.1 and 1.2 in the RCS file foo.c,v:

           rcsdiff -r1.1 -r1.2 foo.c
