我有一个批量转换脚本将各种尺寸的.mkvs变成ipod/iphone大小.mp4s,裁剪/缩放以适应.确定原始尺寸,所需的裁剪,输出文件都工作正常.但是,成功完成第一次转换后,HandbrakeCLI会导致父脚本退出.为什么会这样？我怎么能阻止它？

目前的代码:

#!/bin/bash
find . -name "*.mkv" | while read FILE
do
    # What would the output file be?
    DST=../Touch/$(dirname "$FILE")
    MKV=$(basename "$FILE")
    MP4=${MKV%%.mkv}.mp4

    # If it already exists, don't overwrite it
    if [ -e "$DST/$MP4" ]
    then
        echo "NOT overwriting $DST/$MP4"
    else

        # Stuff to determine dimensions/cropping removed for brevity

        HandbrakeCLI --preset "iPhone & iPod Touch" --vb 900 --crop $crop -i "$FILE" -o "$DST/$MP4" > /dev/null 2>&1

        if [ $? != 0 ]
        then
            echo "$FILE had problems" >> …
