LNDIR(1)		    General Commands Manual		      LNDIR(1)

NAME
       lndir  -	 create	a shadow directory of symbolic links to	another	direc-
       tory 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 con-
       taining links to	the real source, which you will	have  usually  mounted
       from  a	remote machine.	 You can build in the shadow tree, and the ob-
       ject 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, CVS and CVS.adm directories  are	 shad-
       owed 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
       -silent
	      Normally lndir outputs the name of each subdirectory as  it  de-
	      scends into it.  The -silent option suppresses these status mes-
	      sages.

       -ignorelinks
	      Causes  the  program to not treat	symbolic links in fromdir spe-
	      cially.  The link	created	in todir will point back to the	corre-
	      sponding (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 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 ex-
       ists.

       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.
