Question

我在互联网上找到了一个脚本（https://calomel.org/youtube_wget.html），它可以播放youtube视频。

因此，通过简单输入./yt.pl youtubeLink，脚本可以完美地用于单个剪辑。但是我想扩展它并从文本文档中的链接中使用它（download.txt）。所以我在bash中创建了一个循环。循环看起来像这样。

`

    #!/bin/bash
wordCount=$(cat download.txt | wc -l)

for (( number=$wordCount; $number-lt$wordCount;number--))
do
        link=$(sed -n $number"p" download.txt)
        "./yt.pl "$link
        sleep 3
done

这个唯一的问题不起作用。它给我以下错误信息。

/auto.sh: line 7: ./yt.pl http://www.youtube.com/watch?v=KYzUd95h8X4: No such file or directory

如果我只是运行错误消息./yt.pl http://www.youtube.com/watch?v=KYzUd95h8X4的这一部分，它可以正常工作。

这是ssh窗口的完整输出
