转换上并不总是有目录中的文件 [英] Convert files on directories that are not always there

问题描述

我有一个运行时一个任务下载完成后，看是否有FLAC的音频文件，如果是将其转换为MP3的脚本。直到今天我用：

I've got a script that runs when a torrent download is finished to see if there are FLAC audio files and if yes convert them to MP3. Until today I've used:

for file in "$torrentpath"/"$torrentname"/*.flac
do
    ffmpeg -i "$file" -qscale:a 0 "${file[@]/%flac/mp3}"

done

但我意识到，当一个洪流来到含子目录剧本是没用的。我试着插科打诨过去几天查找和如果等方式，但我实在看不出答案。我知道它的存在。

But I realised that when a torrent comes containing sub-directories the script is useless. I've tried messing around for the past few days with "find" and "if" and other ways but I can't really see the answer. I know it's there.

脚本应该只是测试是否有子显示目录和执行这些ffmpeg的，否则直接与转换去了。

The script should just test if there are sub-dirs and execute ffmpeg on those, otherwise directly go with the conversion.

任何一点蛛丝马迹将AP preciated。

Any little hint will be appreciated.

推荐答案

要处理任意子目录在bash：

to handle arbitrary subdirectories in bash:

shopt -s globstar nullglob
for file in "$torrentpath/$torrentname"/**/*.flac
do ...
