Shell：复制某些类型的文件以保持目录结构

Question

Say I have a folder following the structure below:

$ ls /tmp/level1
level2_folder1    level2_folder2
$ ls /tmp/level1/level2_folder1
input output script.py ...
$ ls /tmp/level1/level2_folder2
input output script.py ...

I want to copy all the Python scripts ONLY to somewhere else but keeping the existing structure. Let's say I want to copy the level1 folder to home/ so it should looks like this:

$ ls /home/level1
level2_folder1    level2_folder2
$ ls /home/level1/level2_folder1
script.py 
$ ls /home/level1/level2_folder2
script.py

How could I do that?

Answer 1

rsync -avz --include "*/" --include "*.py" --exclude "*" /tmp/level1 /home

Answer 2

cd /tmp && find level1 -name '*.py' -print0 | cpio -pd0 /home
