Powershell pass parameters to script file

The first and arguably see what I did there the easiest way to get command line arguments is to write something like the following:. This is a case where you will need to run the saved file from the ISE Console and supply a value for the argument. To make sure PowerShell executes what you want, navigate in the command line to the same directory where you will save your scripts.

It will echo back FOO. The scripts for this article can be found here. One nice ability of reading the arguments this way is that you can pass in an arbitrary number of arguments if you need to. For one thing, you can accidentally pass in parameters in the wrong order.

I will outline the preferred method below. This is what you might expect, but say you had multiple parameters and wanted to make sure you had assigned the right value to each one. You might have trouble remembering their names and perhaps their order. Type in the same command as above but add a dash - at the end. PowerShell should now pop up a little dropdown that shows you the available parameters. In this case, you only have the one parameter, param1. Hit tab to autocomplete and enter the word test or any other word you want, and you should see something similar to:.

If you run the script from directly inside PowerShell itself, as opposed to the ISE, tab completion will still show you the available parameters, but will not pop them up in a nice little display. By default, PowerShell will use the position of the parameters in the file to determine what the parameter is when you enter it.

So you need to handle Arguments. Improve this answer. In unnamed parameters method, you cannot have more control with inputs and powershel script itself look unclear to understand the process.

To overcome this, you can pass arguments by named parameter. To get arguments by name, we need to use param statement.

You can set an argument as Mandatory parameter to force user to enter the specific argument to run script. It is new to V2. Good catch regarding the -file parameter I had forgotten that.

I'll have to install V2 before I can try your suggestion. When you say this is breaking a basic security feature, what does "this" you mean? Calling a PowerShell script from Cmd. Passing parameters to the script?

Sorry I should have been more clear. The calling the script without explicitly calling powershell. I'm not saying it is a significant security feature for you personally and it is security through obscurity which I am not always a fan of anyway. To add to EBGreen's comment, the basic security problem that PowerShell's tries to avoid is folks double-clicking on PS1 files attached to email and having the script run. That's why PS1 files are only associated with an editor by default.
