Trying to loop through lines on stdin

Question

I would like to make a short script that will eventually run a quiz.

I'm trying to read stdin, which contains a new-line delimited list of words, for example:

vestirse
lavarse
lavarse los dientes
ducharse 
bañarse

My program so far doesn't seem to be converting input into any type of iterable array:

read inputlines
IFS=$'\n' read -rd '' -a y <<<"$inputlines"

for line in "${lines[@]}"
do
  echo "$line"
done

Now if I run pbpaste | bash wordlearner.bash nothing is printed at all, even though I am expecting (at this point) basically a perfect echo of what was input.

How do I store stdin to be looped through at a later date?

Answer 1

Use a while loop, and then ask for input to read though /dev/tty?

while read -r line; do
  echo "$line"
  echo "What do you think?"
  read -r answer < /dev/tty
done

Alternative use mapfile to slurp all lines into an array?

mapfile -t lines
for line in "${lines[@]}"; do
  echo "$line"
done
