I want to maintain the directory structure (not the contents of the
directory) in sync across 2 machines. How can I do this?

rdist seems to work fine for copying entire directory trees but I am not
interested in the contents of the directories, just the directory itself.

i.e. if a new directory ../new gets created on Source, I want it get created
on Target. If later, files are added to that directory, I dont want to copy
those files.

Any help appreciated.

Thanks

This is probably a lame way to do it, but i've done it like this:

tar cf foo.tar $(find . -type d)
mv foo.tar /someplace
cd /someplace
tar xf foo.tar

Or, to send them to another machine:

xf -'

I don't think that will do it. When you give tar a directory name as an
argument, it archives the directory's contents. In fact, the above command
will create lots of duplication in the archive; when tar archives "." it
will copy the entire hierarchy, and then when it archives "./subdir1" it
will copy that entire sub-hierarchy -- the result will be that each file
will exist N times in the archive, where N is its nesting depth.

You're absolutely right about that, and i feel like an idiot.
i know i've zipped up dir structures before, though, and now need to
rediscover how i did it.

ignore my other posts, they have a fatal mistake in them. Here's a solution
using GNU tar:

tar cf - --no-recursion $(find . -type d) | ssh remote 'cd tmp && cat | tar
xf -'

(and this one i tested before posting ;)

This will not work as tar will descend directories....

Use "star". It has a -D option to supress directory descending
and which doesn't descnd dirs if the filenames are in a "list" file

find . -type d -print | star -c list=- > out.tar

I'd use rsync.

rsync -a --include "*/" --exclude "*" source/ target

The include includes all directories, the exclude excludes all files not
previously included.

find <src> -type d -print | (cd <dest>; xargs mkdir)

Except you need to throw in an rsh or ssh:

find <src> -type d -print | ssh <remote> "cd <dest>; xargs mkdir"
