Not the same, but idea that works anyway.

#!/bin/bash  
i='y'  
while [ $i${i:0:1} != n ]  
do  
    # Command(s)  
    read -p " Again? Y/n " i  
    [[ ${#i} -eq 0 ]] && i='y'  
done

Output:
Again? Y/n N
Again? Y/n Anything
Again? Y/n 7
Again? Y/n &
Again? Y/n nnsijf
$

Now only checks 1st character of $i read.
