Summary: Cloud & Datacenter Management MVP, Thomas Rayner, shows how to count backwards in a Windows PowerShell array.

I know I can access the first, second, and third items in an array by using $Array[0], $Array[1], and $Array[2], but how can I count backwards?

Use negative numbers, for example:

$Array = @(‘first’,’second’,’third’)

$Array[0]

$Array[1]

$Array[2]

$Array[-1]

$Array[-2]

$Array[-3]

This will output the following:

first

second

third

third

second

first
