How To Start Writing A Powershell Script
PowerShell is an extremely powerful command-line tool that allows you to do some incredible things! It can be used for almost anything, and it’s easy to use because there are few settings in most cases. All you need to do to write your first script is choose an action (run something) and then type in what commands to run against it.
There are many ways to improve your powershell scripting skills though. Once you have written a couple of scripts, you will probably want to make them more efficient or add additional features. This article will go into detail about how to start writing your own scripts using PowerShell.
Running Your First PowerScript
So let’s get started! We will be creating our very own little mini game where users can compete with each other by clicking a button as quickly as possible. For this article, we will be calling this competition “PowerButton.” I will also include two different modes for players which will change the length of time they have to respond before being eliminated. These modes will be called Burst and Slow, both having a one minute limit.
Here are the steps:
Step 1: Choose Tools > PowerShell gallery item > Upload Module
You will now open up the Windows PowerShell Gallery and look through all of the modules available. Find the module titled Microsoft.Powershell.Commands.UI and click Install from here.
Make a backup of your script

It is very important to make sure that you have an adequate backup of your current script before moving onto writing another one.
This will save you if something goes wrong while editing or replacing the code in the existing script. You can also do this to start off with a new theme, add features, etc.
Write your script
The next step is to actually start writing your script! Before you write a single line of code, you must first decide what your script will do. Will it perform an action for every item in a list? Or will it do something more complex, like updating all of your social media accounts from a given profile?
The first thing you should do is determine what task you want to accomplish. Once that is done, you can begin scripting!
I recommend using PowerTutorials as a source to learn how to script powershell. They have great articles with steps to easily understand commands and concepts.
Test your script

Testing is an integral part of writing any kind of software. You have to test your script frequently, whether you are testing it yourself or asking someone else to run it. This will help make sure that it works properly for you and does not cause problems when executed by others.
There are several ways to test your PowerShell scripts. Some people use free online tools such as PowerToys which can be helpful in determining if your code is working correctly. There also many third-party applications that can aid in debugging of PowerShell scripts.
Use proper naming conventions

Naming your scripts is an important part of writing powerful PowerShell scripts. You do not want to skip this step, as it can get confusing quickly!
Mostly, you will use three parts to identify a script’s function. These parts are typically the first word, the dash, and then the function name. The first word should describe what the script does (for example, “install software” or “configure files”).
The next part - the dash and then the function name - helps tell people how to use your script. This way, they know whether to run it with no arguments or one argument, etc.
And last, the rest of the function name describes what aspect of the program the command runs. For instance, if your script removes unnecessary programs for Windows users, then you could call it RemoveUnneededProgram().
Use source control

Source control is used in software development to retain revisions of files, keep track of which versions you have, and easily revert back to an earlier version if needed.
Source control can be done manually or automatically using tools. Tools such as GitHub allow you to upload your scripts so that people can access them and make changes to them.
Git is the most common type of source control used for writing PowerShell scripts because it’s free and very accessible. You can start small by just sharing one script before investing in paid accounts and additional features.
Once your script is saved in a source control system like Github, other users can download the file directly from the website, making revision history possible!
Writing a powershell script is similar to editing any other kind of document. Your index, bullet points, sub-bullets, paragraphs, and run time statements should all linked together properly and efficiently.
You don’t want your reader to have to think about how to put everything together due to poor formatting.
Tell your friends about PowerShell

Most people these days have access to at least one computer, which is almost always connected to the internet. If you’re not using that computer for work, it can be wasted software capital!
There are many reasons why someone might want to learn how to write their own PowerShell scripts. It’s a great way to add some organizational functionality to your workplace or personal life, and it can even be fun!
Writing your first script isn’t too difficult of concept, but there are several different versions of PowerShell out there that make it slightly tricky to know what version your command line interface (CLI) is.
Get a mentor

Finding a good writing mentor is one of the most important things you can do as a writer. A writing mentor will help you with your craft by giving feedback on your work, answering questions about the industry, and offering guidance in the form of tips and tricks for improving your writing.
There are many ways to find a writing mentor that fits you or even if you start by asking around at local writers’ groups to see who would be willing to review some of your work.
Writing online forums like Reddit and ThePowerShellCommunity are great resources for finding both written and verbal criticism about your writing skills. By reading through the posts, you will probably notice people talking about how to improve their own writing and whether what someone else wrote made sense.
By responding to these comments and conversations, you can get helpful information and even ask specific questions about certain parts of a script. This way you will also gain knowledge from others in the community.
Mentors are not only valuable because they give you advice, but also because they use and understand the language effectively. If you are struggling to write a sentence, then maybe there is a mentor out there who has run into similar issues before and learned something about it.
Finding a writing mentor may seem difficult at first, but don’t let that stop you! It is definitely worth your time investment.
Read blogs and books

Starting with writing your first script can be tricky at times, especially if you are new to PowerShell or even programming as whole. There are many ways to get started, however, you do not need to learn how to code in order to start scripting!
There are many free resources available online that can teach you how to begin writing scripts. You can also visit your local computer store and find some helpful information there as well.
