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 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
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.
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 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.
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.
