       lndir  -  create  a  shadow  directory  of  symbolic  links  to another
       directory tree


       lndir [ -silent ] [ -ignorelinks ] [ -withrevinfo ] fromdir [ todir ]


       The lndir program makes  a  shadow  copy  todir  of  a  directory  tree
       fromdir,  except  that  the shadow is not populated with real files but
       instead with symbolic links pointing at the real files in  the  fromdir
       directory tree.  This is usually useful for maintaining source code for
       different  machine  architectures.   You  create  a  shadow   directory
       containing  links  to  the  real  source,  which  you will have usually
       mounted from a remote machine.  You can build in the shadow  tree,  and
       the  object  files  will  be  in the shadow directory, while the source
       files in the shadow directory are just symlinks to the real files.

       This scheme has the advantage that if you update the source,  you  need
       not  propagate the change to the other architectures by hand, since all
       source in all shadow directories are symlinks to the real  thing:  just
       cd to the shadow directory and recompile away.

       The  todir  argument is optional and defaults to the current directory.
       The fromdir argument may be relative (e.g., ../src) and is relative  to
       todir (not the current directory).

       Note  that  BitKeeper, RCS, SCCS, .svn, CVS and CVS.adm directories are
       shadowed only if the -withrevinfo flag is specified.

       If you add files, simply run lndir again.  New files will  be  silently
       added.  Old files will be checked that they have the correct link.

       Deleting  files is a more painful problem; the symlinks will just point
       into never never land.

       If a file in fromdir is a symbolic link, lndir will make the same  link
       in todir rather than making a link back to the (symbolic link) entry in
       fromdir.  The -ignorelinks flag changes this behavior.


              Normally lndir outputs the  name  of  each  subdirectory  as  it
              descends  into  it.   The -silent option suppresses these status

              Causes the program  to  not  treat  symbolic  links  in  fromdir
              specially.   The  link  created  in todir will point back to the
              corresponding (symbolic link) file in fromdir.  If the  link  is
              to a directory, this is almost certainly the wrong thing.

              This  option exists mostly to emulate the behavior the C version
              of lndir had in X11R6.  Its use is not recommended.

              Causes  any  BitKeeper,  RCS,  SCCS,  .svn,  CVS   and   CVS.adm
              subdirectories to be treated as any other directory, rather than


       The program displays the name of each subdirectory it enters,  followed
       by a colon.  The -silent option suppresses these messages.

       A  warning message is displayed if the symbolic link cannot be created.
       The usual problem is that a regular  file  of  the  same  name  already

       If  the  link already exists but doesn’t point to the correct file, the
       program prints the link name and the location where it does point.
