How to copy an entire directory except one file in each sub-directory via terminal? [duplicate]

I have a folder named 'Java' which has 20 sub folders ('Day-01' to 'Day-20'). Each sub folder has one or two '.wav' files along with few other files. I want to copy the entire directory except the '.wav' files via terminal. How do I do this?

Solution 1:

The easiest way would be to use rsync with the --exclude option to exclude to .wav files from copying:

rsync -av --exclude='*.wav' /path/to/Java /out/dir

Example:

/foobar/Java% tree
.
├── day-01
│   ├── 01.sh
│   ├── 01.txt
│   └── 01.wav
├── day-02
│   ├── 02.sh
│   ├── 02.txt
│   └── 02.wav
├── day-03
│   ├── 03.txt
│   └── 03.wav
├── day-04
│   └── 04.txt
└── day-05
    └── 05.wav

/foobar/out% rsync -av --exclude='*.wav' ../Java .
