Step 1: Launch PowerShell
PowerShell comes pre-installed on Windows, so to start, right-click the Start button and select Windows Terminal. To launch it with administrative rights, choose Windows Terminal (Admin).
Step 2: Verify Script Execution Policy Settings
Before running scripts, check your script execution policy by creating and running a PowerShell script file to ensure it allows script execution for security purposes.
Step 3: Understand PowerShell Cmdlet
A cmdlet is a lightweight, specialized command in PowerShell, forming the building blocks of scripts. Examples include Get-Process or Stop-Service.
Step 4: Differentiate Between Cmdlet and Command
Cmdlets are specific to PowerShell and cannot run independently. Unlike typical commands, cmdlets work with objects while others may work with text streams.
Step 5: Basics of PowerShell Scripting
PowerShell scripting involves creating sequences of commands, including cmdlets, to automate tasks, saved within files that use the .ps1 extension.
Step 6: Components of a PowerShell Script
Scripts can include commands like Get-Process to fetch system details and handle data types such as String, Integer, and Array.
Step 7: Execute the PowerShell Script
Using PowerShell ISE, you can create and execute scripts. After writing a basic script, press the green arrow icon or F5 to run it. For example:
# Prompt for user input $name = Read-Host "Enter your name" # Display greeting Write-Host "Hello, $name! Welcome to PowerShell scripting."
