Powershell is an extremely powerful tool that enables the automation of administrative tasks. This tool is very convenient for system and network administrators because it saves a lot of time. PowerShell also allows you to manage many tasks centrally and therefore simplify the management of systems and networks.
Why use Powershell?
PowerShell is a command line shell and scripting language used in Microsoft Windows operating systems. It provides a task automation framework, allowing users to automate the use of other programs and perform administrative tasks.
PowerShell is a framework of task automation and configuration management from Microsoft. It is a command line interface (CLI) that allows users to automate system administration and configuration tasks.
PowerShell has become an important skill for IT professionals, DevOps engineers, administrators, and security professionals.
The PowerShell Automation tool allows the user to write scripts in the PowerShell scripting language which can be run as a batch file or as a Windows service.
However, to master the Powershell language we advise you to train, the possibilities are endless and it is possible to interact with all Microsoft programs. Even better Powershell can be used with Microsoft 365 and therefore on theAzure environment.
What you need to know about Powershell scripting
Systems can be greatly customized using PowerShell scripts. Therefore, before running the script, you should check if it performs any actions that you do not want. In addition to PowerShell commands, you can also use other commands in PowerShell scripts, such as those in the command prompt (cmdlets). PowerShell scripts can also use external tools.
To avoid being blocked by the execution policy (see the first section of this article), good PowerShell scripts must be digitally signed. You can disable the PowerShell execution policy in case of emergency. Unsigned scripts will then start running, but your system will no longer be secure.
Run scripts
A script must first be downloaded to a directory on the computer before it can be executed. The script’s *.ps1 file is then used to invoke it. Many scripts still require various startup parameters. This information should be provided to you either at the start of the script or in the help, where the available options should be listed. The script must be launched after the syntax “.skript.ps1” if you are in the directory where it is located.
Creating your own scripts
Use an appropriate editor if you want to write your own programs. For example, Microsoft’s open source editor called Visual Studio Code, Windows Integrated Scripting Environment (ISE) PowerShell, and Notepad++.
Use ChatGPT to help you create scripts
ChatGPT is a revolutionary tool, it is capable of creating Powershell scripts simply by asking it precisely for the expected output.
For example: Create a powershell script that allows you to create groups in the Active Directory.

Save time with automation
Thanks to Powershell scripts you can carry out numerous tasks on one or more computers at the same time. For example, installing a program on hundreds of computers in a few minutes.
The Powershell language allows you to communicate on the command line with the Windows operating system. The tool is available on Windows 7, Windows 10 and Windows 11 and all server versions.
In this example proposed by Tutorials-Computers , you can use Powershell to share Windows folders quickly in seconds.
