Looping using while read line, using a variable instead of a file.
 
I created the following.

x="top
middle
bottom"

I would like to make the following work.

while read line
do

echo $line

done

instead of importing a file I would like to use the variable $x I tried using pipes, but with no luck. My goal is to read one line at a time, but not have to export my data to another file, I would like to keep it all within one script.

Please help.

Try a here string.

Code:
while read line
do
  echo $line
done <<< "$x"
