我在Internet上找到了一个脚本（https://calomel.org/youtube_wget.html），可以wgets youtube视频。
因此，该脚本可通过简单键入./yt.pl youtubeLink完美地适用于单个剪辑。但是我想将其扩展并从文本文档中的链接中使用（download.txt）。因此，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
唯一的问题是行不通的。它给我以下错误消息。
/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的这一部分./yt.pl http://www.youtube.com/watch?v=KYzUd95h8X4它可以正常工作。
这是SSH窗口的完整输出

尝试这样做：
#!/bin/bash
while read link; do
./yt.pl "$link" && sleep 3
done < download.txt
