Question

I found a script on the Internet(https://calomel.org/youtube_wget.html) that wgets youtube videos.

So the script works perfectly for a single clip by simple typing ./yt.pl youtubeLink .
But I want to scale this up and use it from links in a text document (download.txt)
. So I created a loop in bash. The loop looks like this.

`

    #!/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

The only problem with this it doesn’t work. It gives me the following error message.

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

if I just run this part of the error message ./yt.pl http://www.youtube.com/watch?v=KYzUd95h8X4 it works fine.

Here is the complete output of the ssh window

Try doing this :

while read link; do
    ./yt.pl "$link" && sleep 3
