Answer 1

That's better

cat myfile.txt | while read line; do
    echo "$line"
done

or even better (doesn't launch other processes such as a subshell and cat):

while read line; do
    echo "$line"
done < myfile.txt

If you prefer oneliners, it's obviously

while read line; do echo "$line"; done < myfile.txt
