Arguments Before we start creating our program that will remove the background from images let’s go over arguments in shell scripts. Arguments are supplied to shell scripts are separated by a space " ", as opposed to options which start with a -<character> or --<word>.

In this article we will put together some of the pieces from the last 2 articles, and build our first program. If you have missed the first articles, then you can catch up here before continuing with this article.
Getting Started We are going to make our first script / program. This first program is really just setting up some building blocks for our next program we will write, that will remove the background from an image.
In this article, learn about installing a package manager. If you missed it, check out the first article in the series where we learned about using your terminal. This article builds upon that foundation.

This is part one of a series of articles to help HVAC technicians (or others) get started in developing their skills to program. This can help to automate everyday tasks or just familiarize themselves with some of the tools used by programmers.
Why I think if nothing else, this series can help gain knowledge, tips, and tricks to make you more comfortable with your computer. I hope that you will at least learn how to use your terminal application and more specifically vim motions and keybindings (more on that in another article).
