LNDIR(1)                FreeBSD General Commands Manual               LNDIR(1)

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

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

DESCRIPTION
       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, CVS, CVS.adm, .git, .hg, RCS, SCCS, and .svn
       directories are shadowed only if the -withrevinfo flag is specified.
       Files with names ending in ~ are never shadowed.

       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.

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

       -ignorelinks
              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.

       -withrevinfo
              Causes any source control manager subdirectories (those named
              BitKeeper, CVS, CVS.adm, .git, .hg, RCS, SCCS, or .svn) to be
              treated as any other directory, rather than ignored.

DIAGNOSTICS
       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
       exists.

       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.
