Introduction to UNIX with Shell Scripting
1) This is a multi-faceted project. Write a script that will take the information from the data file and make the output as shown below. Also, write a menu that will allow the printing, addition or deletion of a book from the data file.
2) Requirements of the script:
a) You can use any shell, but you must identify the script on the first line.
b) Must start with the input data files exactly formatted as shown below.
c) Write a menu system, using sub-functions, that will allow the following functionality:
a. Format and send the data to the screen, as formatted in section 4.
b. Print to classroom printer.
c. Add a book to the database.
d. Remove a book from the database.
d) The menu must show on the screen in color. Please use a different color for each function.
e) Fully document (comment) all aspects of your script. Explain what you're doing. Points will be deducted for any undocumented entries.
f) A looping structure MUST be used to process the data files someplace in the script.
g) The file output must be sorted by ISBN, the third column. h) Make sure the ISBN numbers are formatted like the example output.
i) Make sure that when the script is run that the current date is shown.
j) Your script MUST be called “project2.ksh”.
k) The data file MUST be called “books.data”

Explanation / Answer
NOTE: Once you run the script type ctrl+c to terminate because the script will infinitely show the menu options to manipulate the book inventory.
Currently the printInventory() function will send the output to your default class printer, but if you want to change to another printer you have to make changes accordingly.
Write your name wherever you see <Fill your name>
Code:
#!/bin/ksh
# program to manage book inventory
# script name: project2.ksh
# function to print the inventory in formatted output on the console
showInventory()
{
# printing the formatted output
echo '****************************************'
echo '* CIS129 Project 2 <Fill Your Name> *'
echo "`date`"
echo '****************************************'
printf "%-25s %-25s %-25s " "Author" "Name of Book" "ISBN">/tmp/outfile
# fetching the lines from file books.data and printing in formatted output to console
while read line
do
echo $line|awk -F"," '{isbn=substr($3,1,3) "-" substr($3,4,4) "-" substr($3,8,5) "-" substr($3,13,1); printf "%-25s %-25s %-25s ", $1, $2, isbn;}'>>/tmp/outfile
done<books.data
# displaying the formatted output
cat /tmp/outfile
}
# function to print the inventory to printer
printInventory()
{
# printing the formatted output
echo '****************************************'
echo '* CIS129 Project 2 <Fill Your Name> *'
echo "`date`"

done<books.data
# check the below command as i do not have printer configured to my system
cat /tmp/outfile|lpr
}
# add the book to database
addbook()
{
# enter the author name want to add

# adding the new book information to books.data database

}
# remove a particular book from database
removebook()
{
# getting the book user want to delete
echo "Enter the book name to delete: "
read book
# removing the book user want to delete and redirecting to temporary file
grep -v "$book" books.data>/tmp/outfile
# updating temporary file to books.data database
cat /tmp/outfile>books.data
}
while true

# displaying the menu with options
echo '****************************************'

echo "`date`"
echo '****************************************'
echo -e "e[1;33m 1. Show the book inventory to the screen. e[0m"

echo -e "e[1;35m 3. Add a book to the inventory. e[0m"
echo -e "e[1;36m 4. Remove a book from the inventory. e[0m"
# Ask user for the choice of menu and call appropriate functions
echo 'Please select a number from the list below (1 – 4) '
read choice
if [ $choice == 1 ]
then
