lndir(1X)
X11R6
NAME
  lndir - create a shadow directory of symbolic links to another directory
  tree

SYNOPSIS
  lndir fromdir [todir]

DESCRIPTION
  lndir 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 NFS mounted from a machine of a different architecture,
  and then recompile it.  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 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 shadow directories are symlinks to the real thing: just cd to the shadow
  directory and recompile.

  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 RCS, SCCS, and CVS.adm directories are not shadowed.

  Note also that if you add files, you must run lndir again.  Deleting files
  is difficult because the symlinks will point to places that no longer
  exist.

BUGS
  The patch routine needs to be able to change the files. You should never
  run patch from a shadow directory.

  Use a command like the following to clear out all files before you can
  relink (if the fromdir has been moved, for instance):

	    find todir -type l -print | xargs rm

  The following command will find all files that are not directories:

	    find . \! -type d -print
