How can I do foreach *.mp3 file recursively in a bash script?

Question

The following works fine within the current folder, but I would like it to scan sub folders as well.

for file in *.mp3

do

echo $file

done

Answer 1

This works with most filenames (including spaces) but not newlines, tabs or double spaces.

find . -type f -name '*.mp3' | while read i; do
   echo "$i"
done

This works with all filenames.

find . -type f -name '*.mp3' -print0 | while IFS= read -r -d '' i; do
   echo "$i"
done

But if you only want to run one command you can use xargs example:

find . -type f -name '*.mp3' -print0 | xargs -0 -l echo
