Hello,
I am trying to write a simple script in Linux that will choose one of the options from the menu(add, subtract, mulitply, divide), and do one of the operations...
I do not know exactly where to put the options for the input of the numbers...i think that is the part that is messing up the script...

here is what i have:

#!/bin/sh
clear
echo "M To do Multiplication"
echo "D To do Division"
echo "Q To quit"
read option
while [ $option != Q]

echo "Please enter a number"
read num1
echo "Please enter another number"
read num2
do
case $option in
A) echo "THe sum of $num1 and $num2 is: `expr $num1 + $num2`";;
S) echo "The difference of $num1 and $num2 is: `expr $num1 - $num2`";;
M) echo "$num1 multiplied by $num2 is: `expr $num1 * $num2`";;
D) echo "$num1 divded by $num2 is: `expr $num1 / $num2`";;
*) echo "That was an invalid selection";;
esac
while [option = Q]
do
exit
echo "Good Bye"

The while construct is


So your bash script could look something like
