My PowerShell script file is located in C:/this-folder/that-folder/another-folder/powershell-file.ps1.
How do I get a variable that returns C:/this-folder/that-folder/another-folder/?
In PowerShell 3.0 you can get it with the new $PSScriptRoot variable, and with $PSCommandPath you can get the full script path.
There's also a great post by MVP Keith hill you may want to check: Determining $ScriptDir Safely
You can use a standard .NET method:
$dirName = [System.IO.Path]::GetDirectoryName("c:\temp\abc\myproj1\newdata.txt")
From PowerShell: Get parent directory name from file or directory path.
$dirName = "c:\temp\abc\myproj1".I'm assuming you want to know what folder your script is running in when it's being run.
This should do it:
Split-Path $MyInvocation.MyCommand.Path
powershell-file.ps1can get the parent directory path of itself, but it would be good to make that explicit.
