LNDIR(1)		     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 direc-
     tory,  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, 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.

OPTIONS
     -silentNormally  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 (sym-
	    bolic 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  BitKeeper, RCS, SCCS, CVS and CVS.adm subdirectories 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  pro-
     gram prints the link name and the location where it does point.
