Problems converting WAV to ALAC by a batch job I use the following code to convert WAV to ALAC (bash, macOS 10.12.1): find . -type f -iname "*.wav" | while read fn; do ffmpeg -i "$fn" -acodec alac "${fn%.wav}.m4a"; done But there seems to be a mistake since it prints warnings like this: n---8085/03_Part_III.wav: No such file or directory The correct path would be: Bad_Religion/wav/Bad_Religion---8085/03_Part_III.wav For some reason the path is truncated. What's wrong with the command?

Your file names are not actually being truncated. Here, `ffmpeg` is trying to read commands from its input stream. Unfortunately, this is the same stream `read` is using to determine filenames, so it appears that parts of these filenames are not being read. To fix this, you should tell `ffmpeg` to disable interaction on the input stream with the `-nostdin` flag.
