PowerShell For Each Loop Examples

If you want to iterate over a collection of items in PowerShell, you can make use of the ForEach-Object cmdlet.

Syntax:

ForEach-Object
            [-InputObject ]
            [-Begin ]
            [-Process] 
            [-End ]
            [-RemainingScripts ]
            [-WhatIf]
            [-Confirm]
            []

Examples: Iterate over an Array of Strings

$cityNames = @("New York", "Los Angeles", "Chicago", "San Francisco")

# Loop through the array using ForEach-Object
$cityNames | ForEach-Object {
    Write-Host "$_"
}

Output:

New York
Los Angeles
Chicago
San Francisco

Examples: Iterate over an Array of Numbers

$numbers = @(10, 20, 30, 40, 50)

$numbers | ForEach-Object {
    Write-Host "$_"
}

Output:

10
20
30
40
50
