Running Your First Script
Before you can harness the full power of PowerShell, you need to understand how PowerShell scripts work and how to run them. A PowerShell script is a text file containing a series of PowerShell commands that automate tasks or perform complex operations. These script files typically use the .ps1 extension, which tells PowerShell that the file contains script code ready to be executed. Script files let you save, reuse, and share your automation solutions easily.
123# Simple PowerShell script that prints Hello World Write-Output "Hello World"
This script demonstrates a basic PowerShell command saved in a script file. When you save this code in a file named hello.ps1 and run it in PowerShell, it displays the message Hello World on the screen.
However, before running scripts, you need to be aware of PowerShell's script execution policies. These policies are security settings that control how and when scripts can be run on your system. By default, PowerShell may restrict the execution of scripts to prevent the accidental or malicious running of code. If you try to run a script and receive a warning or error about execution policies, you may need to change the policy using the Set-ExecutionPolicy command. Use this command with care, and always understand the security implications of changing execution policies.
To run a script, open PowerShell, navigate to the folder containing your .ps1 file, and enter ./hello.ps1. If execution policies allow, your script will run and display the output. This is the foundation of working with PowerShell scripts and automating your tasks.
