shell code 작성 시 carriage return 문자 제거

\r carriage return

cat /sd1/hayeong/data/train.txt | tr -d '\r' | while read line
do
    train_path="/sd1/hayeong/data/LJSpeech-1.1/train"
    dev_path="/sd1/hayeong/data/LJSpeech-1.1/dev"

    tmp="/sd1/hayeong/data/LJSpeech-1.1/wavs/${line}.wav"
    echo ${tmp}
    mv $tmp $train_path
done

오랜만에 shell.. tr 까먹어서 당황했다. .
