Use Powershell console to run a script from a different folder

Question

I have a Powershell script that takes two arguments.

param([string]$folder, [string]$filename)

When I open a Powershell shell, navigate to the folder that contains the script, and run it from there, the script is executed correctly:

C:\scriptfolder> ".\script.ps1" "C:\folder for argument" "filename.ext"

When I try to run the script from a different folder, I get an error message:

C:\otherfolder> "C:\scriptfolder\script.ps1" "C:\folder for argument" "filename.ext"

At line:1 char:nn

Unexpected token '"C:\folder for argument"' in expression or statement.

How can I run this script from another folder?

You need to dot-source the path to the ps1 file . "C:\scriptfolder\script.ps1" "C:\folder for argument" "filename.ext" or use the & call operator — Theo

In order not to leave this question as 'Unanswered', here my comment as answer

There are two ways to do what you want. The first is by using dot-sourcing:

. "C:\scriptfolder\script.ps1" "C:\folder for argument" "filename.ext"

The second method would be by using the `& call operator

& "C:\scriptfolder\script.ps1" "C:\folder for argument" "filename.ext"

The difference between the two methods is that a script that is invoked using dot-sourcing runs in the current scope, while with the second method, using the call operator, scripts and functions run in a child scope.
