多くのフォーラムや Web サイトを検索して、同じディレクトリ構造を持つ FLAC コレクションから ALAC コレクションを作成しましたが、成功しませんでした。したがって、私は独自のシェル スクリプトをコーディングし、ここで共有して、他のユーザーがそれを使用または改善できるようにすることにしました。

解決したかった問題:

  1. 変換の完全自動化。すべてのディレクトリでスクリプトを実行したくありませんでした。
  2. 再帰的なファイル検索
  3. flac を alac に変換し、アートワークをコピーして、すべての構造をある場所から別の場所に移動します。他には何もありません。
  4. 同じディレクトリにflacファイルとalacファイルを入れたくありませんでした（以下のスクリプトでそれができると思います）

これがスクリプトの結果です。それは私のために働きます、私はそれがあなたにとってもうまくいくことを願っています. Linux Mint と bash シェルを使用しています。

2014-12-08 - いくつかの変更を行い、現在は正常に動作しています。複数のコピーを作成する前に。

Usage is: ./FLACtoALAC.sh /sourcedirectory /targetdirectory

Here are some explanations:

Source: /a/b/c/d/e/   <- e has flac
              /g/f/k  <- k has artwork
                  /l  <- l has mp3

Target: /z/u/v/g/f

when the command is run : ./FLACtoALAC.sh /a/b/ /z/u/

I want the structure look like:
/z/u/v/g/f     <- f was already there
    /c/d/e/    <- e had flac, so created with the tree following source (/a/b) 
    /c/g/f/k   <- k had artwork, so created with the tree following source (/a/b) 

not created l  <- l did not have any of the png,jpg or flac files.

I do not want to create any directory that does not contain png, jpg or flac,
unless it is a parent to one of such those directories.

これを試してください：

#!/bin/bash

src_dir="in"
dst_dir="out"

find ${src_dir} -type f -print0|while IFS= read -r -d '' src_file; do
        dst_file=${src_file/$src_dir/$dst_dir}

        echo "src_file=${src_file} dst_file=${dst_file}"
        mkdir -pv `dirname $dst_file`
        # use above variables and run convert command with it here
done

動作をテストするには:

mkdir in out
cd in
mkdir 1 2 3
find . -type d -exec touch {}/foo {}/bar {}/baz \;
cd ..
./run_my_script.sh

これで、convert function/script/command/whatever をアタッチし、コマンド ラインから読み取れるように改善するだけで済みます (お勧めしsrc_dirます- > ) 。dst_dirman bashgetopts
