Code: Select all#!/bin/bash
while read line
 do
"/usr/bin/wget" $line
sed -i "/$line/d" urls
done  <urls

The while loop read the videos url from the urls file and parse them to the wget for dwonlaod, i write the wget for easy of exmple in this code otherwise i use another script to downlaod the embed videos , the code

Code: Select allsed -i "/$line/d" urls delete the url of videos from the urls file when it is download is complete.

The problem is http address contain the foreward slashes "/" and sed cannot delete them and get error, this is the urls file:
