Read lines to array in Bash

lines_as_array.sh

# Mac OS ships with Bash 3.2, which lacks the read -a option, which makes reading into an array easy
# So this is a replacement
lines="first line
second line
third line"

linesArray=()
while read -r line; do
  linesArray+=("$line")
done <<< "${lines}"

# verify the array is initialized correctly
echo "${#linesArray}"
echo "${linesArray[@]}"
for line in "${lines}"; do
  echo "line: ${line}"
done
