I have a simple script which reads lines from a file (using a while-read loop) and asks the user whether to perform an action on each entry. The problem is that when I use read to prompt the user input, the user read gets data from the file read. Here is the code:

(Toggle Plain Text)

#!/bin/bash

[ -f "download.list" ] || exit 1

while read LINE
do
        URL=${LINE#*,}
        TITLE=${LINE%,*}
        echo "Download $TITLE [y/n]: "
        read RESPONSE

        if [ $RESPONSE = 'y' ]; then
               echo "curl -O $URL"
        fi

done < download.list

The $LINE, $URL & $TITLE are set correctly. What happens is that $RESPONSE is set to the next line in 'download.list' rather than prompting the user for input.

Can anyone tell me what I am doing wrong?

Thanks,
