Using File Descriptors, traverse a list
I have written this code, and according to my research it SHOULD be going down the list until it is finished, but I am getting blank feedback. Nothing is being output as far as I can tell.

#!/bin/sh
while echo Enter to start traversing
read enter
do
read list <&3
echo $list
done

any ideas on whats going on? it's a rather straight forward experiment.
