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?
This question is related to
powershell
scripting
In powershell :
$this_script_path = $(Get-Item $($MyInvocation.MyCommand.Path)).DirectoryName
$parent_folder = Split-Path $this_script_path -Leaf
You can simply chain as many split-path
as you need:
$rootPath = $scriptPath | split-path | split-path
Split-Path -Path (Get-Location).Path -Parent
In PowerShell 3, $PsScriptRoot
or for your question of two parents up,
$dir = ls "$PsScriptRoot\..\.."
You can use
(get-item $scriptPath).Directoryname
to get the string path or if you want the Directory type use:
(get-item $scriptPath).Directory
You can split it at the backslashes, and take the next-to-last one with negative array indexing to get just the grandparent directory name.
($scriptpath -split '\\')[-2]
You have to double the backslash to escape it in the regex.
To get the entire path:
($path -split '\\')[0..(($path -split '\\').count -2)] -join '\'
And, looking at the parameters for split-path, it takes the path as pipeline input, so:
$rootpath = $scriptpath | split-path -parent | split-path -parent
I've solved that like this:
$RootPath = Split-Path (Split-Path $PSScriptRoot -Parent) -Parent
If you want to use $PSScriptRoot you can do
Join-Path -Path $PSScriptRoot -ChildPath ..\.. -Resolve
To extrapolate a bit on the other answers (in as Beginner-friendly a way as possible):
Check the object type with the GetType Method to see what you're working with: $scriptPath.GetType()
Lastly, a quick tip that helps with making one-liners: Get-Item has the gi
alias and Get-ChildItem has the gci
alias.
