    I was trying with the parameter expansion

    while read x; do
    echo ${x:2:1}
done

    then I realized that this code never reads the last line, whereas it does with bash on my system. Indeed I also tried with the NON-solution to see if the code replicates the input, but it always removes the last line.

    while read x; do
    echo $x
done

    Can anyone help me understand why?
