Run Scripts with Parameters in MEMCM (R.I.P. SCCM)

How do you use Parameters in MEMCM's (R.I.P. SCCM) Run Scripts?

How do you use Parameters on the Run Scripts feature? You get three guesses, but the first two don't count. That's right, you create a script with standard PowerShell Parameters and you build it out in MEMCM. In your MEMCM console, navigate to Software Library > Overview > Scripts. If you're not familiar with Run Scripts in MEMCM, check out my previous Blog articles on it.

Click on Create Script. In the Create Script Wizard that pops up input a Script Name, pick between PowerShell or PowerShell in your Script Language, import or paste in your script with Parameters, and click on Next.

My demo script for this article (scroll alllll the way down, it's at the bottom) is about an 8 out of 10 on the cool factor, and about a 3 out of 10 on the usefulness factor. Long story short, the script will make a computer talk. There are two Parameters that you can input, one for "what do you want to say?" and the other for "who is your message from?" both of which are spoken. The script sets a computer's volume to 80%, says what time it is, makes a snarky remark about the time of day, says your message (the first parameter), and then it says who the message is from (the second parameter).

The next screen in the Create Scripts Wizard shows you the Parameters from your script. You can highlight a Parameter and click on Edit if you want to change anything on it.

You can edit any of the Parameter properties, including those you did or did not specify when you originally wrote the script. I find it best to input a "Friendly Name" for my Parameter and also specify whether it is "Required" to be filled in. Once you get it perfect, click OK

If you edited your Parameter properties, you'll see things like the friendly name reflected back on the Create Scripts Wizard. Once you're ready click on Next, Next, and Finish.

You'll still need to Approve your script before you can use it. Right click on your script and click Approve/Deny. Follow the Approve or Deny Script Wizard to approve your script. If you can't Approve/Deny the script yourself or you need additional info on the process, go to my previous article on CMPivot and Run Scripts, and scroll down to the part about creating and approving scripts.

To test out your script, find some unsuspecting coworker with a sense of humor, right click on their Device, and click on Run Script

In the Run Script Wizard, highlight your script and click on Next. You'll then see where to input your Parameters on the next page of the wizard. Click in the Value fields to fill in your message and who it's from. Once you're ready to go, click on Next

Check the Summary really quick to make sure everything looks good, click Next, and wait for laughter to ensue.
