Using recursion with a command loop. What's the syntax?

Question

I use the following loop to do .flac --> .mp3 transcoding:

for file in *.flac; do $(flac -cd "$file" | lame --preset fast extreme - "${file%.flac}.mp3"); done

The directory, of course, must contain .flac files for this to work. What I'd like to be taught is the syntax in order to make this command work recursively. The aim is to cd to the directory containing all the subdirectories of .flac files and have the command loop through them all.

Thanks a lot in advance.

Answer 1

Create a file ~/bin/flac2mp3 with the contents:

#!/bin/bash
file="$1"
flac -cd "$file" | lame --preset fast extreme - "${file%.flac}.mp3"

Then run find . -name '*.flac' -exec ~/bin/flac2mp3 '{}' \;

It can be done without using a separate file for ~/bin/flac2mp3 but I think using a separate file is simpler and more clear.
