I am having a question regarding the command line argument question

#1

Create a shell script called /home/bob/calculate-price.sh and it must accept 2 numbers as command line parameters $1 and $2 . It must print the product (multiplied value) of the numbers as output. But this time in a new format - The total price for items is 1000 dollars

I can solve it if I am using read for two variables, but I want to understand the buil in variable solution for this problem

#2

Simplest form. Note I am not looking at the question, because you didn’t give a link to it, but this program prints the product of the two command line arguments.

#!/usr/bin/bash

echo "The total price for items is $(($1 * $2)) dollars"

And run it

 /home/bob$ ./calculate-price.sh 10 100
The total price for items is 1000 dollars
 /home/bob$

And with different arguments…

 /home/bob$ ./calculate-price.sh 2 500
The total price for items is 1000 dollars
 /home/bob$
