Getting the current script directory in PowerShell

One thing to remember when developing PowerShell scripts is that your current value in $PWD is the process’ current directory not the one where the script was stored.

In my desire to break out a few functions into a common file in order to load them “dot-sourced” (so that the functions become global) I realised I needed help!

In comes a new function from the PowerShell Team Blog. It’s going straight into my PowerShell Profile: Get-ScriptDirectory. It does exactly as the name says, it gets the current directory that script is executed from.

<snip>

1. function Get-ScriptDirectory
2. {
3. $Invocation = (Get-Variable MyInvocation -Scope 1).Value
4. Split-Path $Invocation.MyCommand.Path
5. }

</snip>

So that now from my script that requires the Common-Functions.ps1 (located in the same directory) I can call:

1. # Load up our common functions
2. $commons = Join-Path (Get-ScriptDirectory) “Common-Functions.ps1″;
3. . $commons;

Love,
Reddog.
