How to use `while read` (Bash) to read the last line in a file if there’s no newline at the end of the file?

Question

Let’s say I have the following Bash script:

while read SCRIPT_SOURCE_LINE; do
  echo \"$SCRIPT_SOURCE_LINE\"
done

I noticed that for files

In your first example, I'm assuming you are reading from stdin. To do the same with the second code block, you just have to remove the redirection and echo $REPLY:

DONE=false
until $DONE ;do
read || DONE=true
echo $REPLY
done
