Addition of Two Numbers in Bash

In this article I would like to share with you one of my passion in programming writing Bash Script in Linux to automate or to make simple programs under Linux operating system. This program is very simple it will ask the user to enter two numbers and then it will display the sum of the two numbers to the user.

I am using Cgywin a linux distribution operating system that enables you run linux commands under windows it is totally free to download over the Internet here is the link https://www.cygwin.com/.

I hope you will find my simple script useful in your learning bash scripting programming in Linux operating system. If you have some questions feel free to send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you and Happy Programming.
