PowerShell Objects

last modified February 20, 2025

In this article, we will explore objects in PowerShell.

PowerShell is an object-oriented scripting language. Everything in PowerShell is an object, including variables, strings, and system components.

Creating Custom Objects

You can create custom objects using New-Object or [PSCustomObject].

custom_object.ps1

$obj = New-Object PSObject -Property @{ Name="Alice"; Age=30 }
Write-Output $obj

Getting Object Properties

You can access object properties using dot notation.

get_properties.ps1

$process = Get-Process | Select-Object -First 1
Write-Output $process.Name

Modifying Object Properties

You can modify object properties after creation.

modify_object.ps1

$obj = [PSCustomObject]@{ Name="Bob"; Age=25 }
$obj.Age = 26
Write-Output $obj

Filtering Objects

You can filter objects using Where-Object.

filter_objects.ps1

$processes = Get-Process | Where-Object { $_.CPU -gt 10 }
Write-Output $processes

Sorting Objects

You can sort objects using Sort-Object.

sort_objects.ps1

$processes = Get-Process | Sort-Object -Property CPU -Descending
Write-Output $processes

Selecting Object Properties

You can select specific properties using Select-Object.

select_properties.ps1

$processes = Get-Process | Select-Object Name, CPU
Write-Output $processes
