I have a problem with the Nesting of case statements.
This is a Simple restaurant program which simulates food ordering.
I used Case statements to Display Multiple nested menus base on the users choice
But i seem to have a problem with the esac,seems my nesting is wrong.Pleas any help or advice will be appreciated.
#!/bin/bash
clear
# display menu
echo "-------------------------------"
echo " Superman Restaurant"
echo "-------------------------------"
echo " Main Menu"
echo "-------------------------------"
echo " $(date)"
echo "-------------------------------"
echo "1. Display Meal Menu."
echo "2. Display Drinks."
echo "3. Display Desert."
echo "4. Exit"
# get input from the user
read -p "Enter your choice [ 1 -4 ] " choice
# make decision using case..in..esac
case $choice in
