Looping through lines in a file in bash, without using stdin

Question

I am foxed by the following situation.

I have a file list.txt that I want to run through line by line, in a loop, in bash. A typical line in list.txt has spaces in.

Answer 1

You must open as a different file descriptor

while read p <&3; do
    echo "$p"
    echo 'Hit enter for the next one'
    read x
done 3< list.txt
