How to get the Parent's parent directory in Powershell?

Question

So if I have a directory stored in a variable, say:

$scriptPath = (Get-ScriptDirectory);

Now I would like to find the directory two parent levels up.

I need a nice way of doing:

$parentPath = Split-Path -parent $scriptPath
$rootPath = Split-Path -parent $parentPath

Can I get to the rootPath in one line of code?

Answer 1

Version for a directory

get-item is your friendly helping hand here.

(get-item $scriptPath ).parent.parent

If you Want the string only

(get-item $scriptPath ).parent.parent.FullName

Version for a file

If $scriptPath points to a file then you have to call Directory property on it first, so the call would look like this

(get-item $scriptPath).Directory.Parent.Parent.FullName

Remarks
This will only work if $scriptPath exists. Otherwise you have to use Split-Path cmdlet.
