I have all my music in a folder /media/kalenpw/MyBook/Music/ABunchOfOtherFoldersWithFilesInside. I want to copy all of the mp3s to /media/kalenpw/HDD/Music so I used:

cp -R /media/kalenpw/MyBook/Music/*.mp3 /media/kalenpw/HDD/Music

however this only copied the mp3s in the root music folder and did not open any of the artist subdirectories and copy those files.

I was under the impression -R would recursively copy all the files. How can I achieve said goal?



find /media/kalenpw/MyBook/Music/ -name '*.mp3' -exec cp {} /media/kalenpw/HDD/Music \;

The reason for your command not working is that names containing wildcards (*.mp3) are expanded before the command is run, so if you had three files (01.mp3, 02.mp3, 03.mp3) your effective command was:

cp -R /media/kalenpw/MyBook/Music/01.mp3 /media/kalenpw/MyBook/Music/02.mp3 /media/kalenpw/MyBook/Music/03.mp3 /media/kalenpw/HDD/Music

As you can see -R has no effect in this case.

  • I recommend -iname instead of -name in case any files end in .MP3. – Olathe Jul 24 '16 at 4:12

You have specifically mentioned the files(s)/directory(ies) to be copied as using *.mp3 i.e. any file/directory name ending in .mp3.

So any file ending in .mp3 in /media/kalenpw/MyBook/Music/ directory and similarly, any directory ending in .mp3 in /media/kalenpw/MyBook/Music/ will be copied, recursively. If there is no such matched file/directory, nothing will be copied.

Now to copy all .mp3 files from /media/kalenpw/MyBook/Music/ recursivley to directory /media/kalenpw/HDD/Music/:

  • Using bash:

    shopt -s globstar
    cp -at /media/kalenpw/HDD/Music /media/kalenpw/MyBook/Music/**/*.mp3
  • Using find:

    find /media/kalenpw/MyBook/Music -type f -name '*.mp3' -exec cp -at /media/kalenpw/HDD/Music {} +

You can also use cpr:

$ cd /media/kalenpw/HDD/Music
$ cpr -p '/\.mp3$/' '/media/kalenpw/MyBook/Music/'

Note that without -p cpr will preserve complete directory paths on copied filenames.
-r can be used (instead of -p) to preserve the path under '/media.../Music/'.
Also cpr will take care that no file is overwritten, appending a number starting at '0001' to any repeated filename copied.


Suppose that you have a bunch of .docx, .mp3, .txt and .xlsx files stored in this directory structure:


...and you want to recurse into all such directories in order to copy all found .mp3 files to /home/me/music/ but you do not want to preserve such directory tree in the destination (i.e. you want all found .mp3 files to be copied to /home/me/music/ instead of copied to respective directories such as /home/me/music/dir1/, /home/me/music/dir1/dir11/ et cetera).

In such case, at the shell terminal (bash) first run this command in order to access the root of your file search:

cd /files

...and then run this command:

for i in `find . -iname '*.mp3'`; do cp $i /home/me/music/; done

In case you do want to preserve the source's directory tree in the destination, run this command instead (after running cd /files):

find . -iname '*.mp3' | cpio -pdm /home/me/music/

On the above commands, the search is case-insensitive (i.e. matches .mp3, .MP3, .mP3 and .Mp3). Use -name instead of -iname if you want the search to be case-sensitive (e.g. using -name for the .mp3 string of characters will match files ending with .mp3 but not those ending with .MP3, .mP3 nor .Mp3).
