Merge (combine) directories using rsync

Question

I need to create a deploy script to combine the following directory structure:

├── LIB_COMMON
│   ├── file1.php 
│   ├── file2.php
│   ├── file3.php
│   └── file4.php
├── LIB_CZ
│   ├── file2.php
│   ├── file3.php
│   ├── file5.php
│   └── file6.php

...which result should look like:

├── LIB_RESULT
│   ├── file1.php ...with content from LIB_COMMON
│   ├── file2.php ...from LIB_CZ
│   ├── file3.php ...from LIB_CZ
│   ├── file4.php ...from LIB_COMMON
│   ├── file5.php ...from LIB_CZ
│   └── file6.php ...from LIB_CZ

One way to do it is:

rsync LIB_COMMON/ LIB_RESULT/ --delete-after
rsync LIB_CZ/ LIB_RESULT/

...but this will always transfer many files.

Other way could be:

cp LIB_COMMON/ TMP/ 
cp LIB_CZ/ TMP/
rsync TMP/ LIB_RESULT/ --delete-after

So, Does anyone know an elegant way to achieve this?

Solution

rsync -avz LIB_COMMON/ LIB_CZ/ LIB_RESULT/ --delete-after

This will sync the content of lib_common/ & lib_cz/ to the lib_result/ folder.

That depends; does the destination folder need to be able to sync back to the source folders?
