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
