MP4Box外壳脚本不工作

Question

我试图使用MP4Box连接一个目录中的几个.mp4文件。简单形式的基本命令如下所示：

mp4box -cat 'Film.mp4' -cat 'Credits.mp4' -new Total.mp4

我写了这个剧本，但不管用：

#!/bin/bash
files='*.mp4'; for i in $files; do MP4Box -cat "'"$i"'" -new Total.mp4; done

它只给出：

Error appending '01_Introduction.mp4': Requested URL is not valid or cannot be found
Error - 2 input names specified, please check usage
Error - 2 input names specified, please check usage
Error - 2 input names specified, please check usage
Error - 2 input names specified, please check usage
Error - 2 input names specified, please check usage
Error - 2 input names specified, please check usage
... etc.

我的表情怎么了？

我决定：

#!/bin/bash

rm Total.mp4; files='*.mp4'; for i in $files; do
echo " -cat " "'"$i"'" >>input.txt; done

file="input.txt"; name=$(cat "$file"); 

eval "MP4Box " $name " -new Total.mp4";
