sed cannot delete forward slash in while loop?

[shams]

I am downloading online videos with a bash script this is the code of script test.sh:

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 all

sed -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:

Try quoting the lines:

Code: Select all

sed -i "/\"$line\"/d" urls

This is the modefy code from the previous post:

Code: Select all

#!/bin/bash
while read line
do
echo $line
sed -i "/\"$line\"/d" urls
done < urls

and this is the output of above code:

Code: Select all

# ./test.sh

sed: -e expression #1, char 9: unknown command: `/'

sed can use arbitrary delimeters.

Code: Select all

sed -i '#$line#d' urls

maybe this?
