i need to prompt the user for


a) group of scores
b) calculate the lowest and highest scores and overall average
c) print out to the screen
d ask if user has any more data to process, if so repeat (loop) for a new set of scores if not exit.


i have this much,and trust me i know there is a lot missing



#!/bin/bash


echo
echo -n "Enter the first score (abc to exit): "
read $score


until [[ $first == abc ]]
do
echo -n "Enter the next score: "
read $score







until
echo -n "Enter d if all scores are entered: "
read $score

[[ $score == $score+1 ]]







echo "The result is: $ans"



done


echo "Goodbye"
echo
exit 0






I know I am on the right track, but Unix is new to me (school project) I am just looking for help, ive been around since the dos days and have played some with vb, basic, etc. but its been awhile, any help is appreciated (its due Wednesday!!)

#THIS IS WHAT I HAVE SO FAR, WILL KEEP WORKING


#!/bin/bash

echo
echo -n "Enter the first score (abc to exit): "
read $score

until [[ $first == abc ]]
do
echo -n "Enter the next score: "
read $score




until
echo -n "Enter d if all scores are entered: "
read $score


if [[ $oper == d ]]
then
#this would be the sum of scores
(( $ans == $score + 1 ))
(( $ans == $score + $score + 1 ))

then
#this would be the avg of scores
(( $ans == $score / ?))

then (( $hilo == $score < >))
#this would be highest and lowest

then (( $avg == ))



fi


#print out

echo "The sum is: $ans $hilo $avg"
echo "The High Low scores are $hilo"
echo "The average score is $avg"

echo -n "Do you want to input a new batch of scores? (abc to exit): "
read $score

if [[ $oper == d ]]
then

else
fi
done



echo "Goodbye"
echo
exit 0
