I want to copy my directory structure excluding the files. Is there any option in the tar to ignore all files and copy only the Directories recursively.
You can use find to get the directories and then tar them:
find .. -type d -print0 | xargs -0 tar cf dirstructure.tar --no-recursion
If you have more than about 10000 directories use the following to work around xargs limits:
find . -type d -print0 | tar cf dirstructure.tar --no-recursion --null --files-from -
