#!/bin/bash
# Script to create menus and take action according to that selected menu item.
#
#
while :
do
clear
echo "----------------------------------------------"

echo "----------------------------------------------"
echo "[1] Display"
echo "[2] Add book and change"
echo "[3] Delete data"
echo "[4] Exit/stop"
echo "----------------------------------------------"
echo -n "Enter your menu choice [1-4]:"
read yourch
case $yourch in
1)
echo "Please type the name of the book that you want display";
sorting_book
read book
;;
2)
echo "Please type the name of the book that you want add"; read adding
add_book
;;
3) echo "Please Type the data that you want eliminate " read data
erase_data
;;
4) exit 0
;;
*) echo "Opps!!! Please select choice 1,2,3 or 4"
echo "Press a key. . ."
read -n 1
;;
esac
done
function sorting_book {
while :

read sorting
case $sorting in

grep -e '$book'.* library.txt | sort -t ""| awk -f "" '{print $1,"\t",$2}'

}
function add_book {
