RCSDIFF(1L)                                           RCSDIFF(1L)


NAME
       rcsdiff - compare RCS revisions

SYNOPSIS
       rcsdiff  [ -biwt ] [ -cefhn ] [ -q ] [ -rrev1 ] [ -rrev2 ]
       file ...

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

       The  options  -b, -i, -w, -t, -c, -e, -f, and -h, have the
       same effect as described in diff(1); option  -n  generates
       an  edit  script of the format used by RCS.  The option -q
       suppresses diagnostic output.

       If both rev1 and rev2 are omitted,  rcsdiff  compares  the
       latest  revision  on  the  default  branch  (normally  the
       highest branch on 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, and may actually be attached to any  of  the
       options.

EXAMPLES
       The command

               rcsdiff  f.c

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

DIAGNOSTICS
       The exit status is 0 if there were no  differences  during
       the last comparison, 1 if there were differences, and 2 if
       there were errors.
