如何在bash中的循環中傳遞變量

Question

我在互聯網上找到了一個腳本（https://calomel.org/youtube_wget.html），它用於存放youtube視頻。

因此，通過簡單的輸入./yt.pl youtubeLink，該腳本完美適用於單個剪輯。 但我想要擴展並使用文本文檔中的鏈接（download.txt） 。所以我在bash中創建了一個循環。循環看起來像這樣。

`

#!/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 

唯一的問題與此不工作。它給了我下面的錯誤信息。

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

如果我只是運行這部分錯誤消息./yt.pl http://www.youtube.com/watch?v=KYzUd95h8X4它工作正常。

試着這樣做：

#!/bin/bash 

while read link; do 
    ./yt.pl "$link" && sleep 3 
done < download.txt
