i get stuck with this shell script code
i get stuck here . Anyone could check my work?
the user type a group of upper case letters at a time with 0 at the end. Find and display the first letter in alphabetic order.
For example, input of F, G, K, S, U, G, D, Q, P , the result should be D
Any invalid input character (eg. #, $, 3, a, etc.) should cause an error message and be ignored.

echo "please enter an alphabet"
input3=1
echo "" > temp
while [ "$input3" != "0" ]; do
read input3
echo $input3 > check
if [ "$input3" != "0" ]; then
if [ check1=`grep -w "[A-Z]" check ]; then
echo $input3 >> temp
else
echo input should be upper case alphabet
fi
fi
done
grep -w "[A-Z]" temp > temp1
echo the first letter in alphabetic order is `sort temp1 | head -1`;;
