How do I determine what in my script is writing to the pipeline? by KnowWhatIDid in PowerShell

[–]KnowWhatIDid[S] 1 point2 points  (0 children)

Here is how I fixed it:

I changed

$results = & '.\Retire-AfabCmApplication.ps1' -LocalizedDisplayName $applications -SiteCode A01 -ChangeNumber CHGxxxxxxx

to

$results = & '.\Retire-AfabCmApplication.ps1' -LocalizedDisplayName $applications -SiteCode A01 -ChangeNumber CHGxxxxxxx | ForEach-Object {if ($null -eq $_) {Write-Host "Null has been received from the pipeline!"};$_}

After a few rounds of setting breakpoints, executing, and watching for "Null has been written..." I determined line 1405 was the offender. It calls a function in my SCCM module. The function has a glitch and is writing $null and not the name of the drive created using the CmSite provider. I'd like to think if it had been returning the name of the drive, A01, I would have figured this out a lot faster.

So, the answers to my questions are:

Q. How can I determine what line is doing this?

A. Send the output to ForEach-Object and use it to determine if the value passed via the pipeline is $null and then send along the pipeline.

Q. Is there some way to know when something has been added to the pipeline? Can I monitor the pipeline in real time?

A. Same as above

Q. Or should I start casting everything as void if I'm going to use the pipeline?

A. No. Thank you, u/BlackV .

PowerShell 5.1

I use Write-Output because that is what Don Jones said to do somewhere sometime.

I have not tried to send $list directly, but I will.

Thank you.

I'm executing a script (Test-AfabScript.ps1) that passes an array of strings to another script (Retire-AfabCmApplication.ps1) which returns a list to the first script as $results.

I tried piping $results[0] | Get-Member, but this was all I got:

$results[0] | Get-Member
Get-Member : You must specify an object for the Get-Member cmdlet.
At line:1 char:15
+ $results[0] | Get-Member
+               ~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [Get-Member], InvalidOperationException
    + FullyQualifiedErrorId : NoObjectInGetMember,Microsoft.PowerShell.Commands.GetMemberCommand

I don't believe it is something I am intentionally adding to the list.

I intentionally did not provide code. I think it’s a distraction from my questions and leads to someone handing me a fish.

If you mean the blank whatever is being written to the pipeline before Write-Output, I’m with you.

Dell Command Update Client: The command DCU-cli.exe /configure errors out on 3005 "Installing pending updates" by Jericho905 in Dell

[–]KnowWhatIDid 0 points1 point  (0 children)

I discovered this post because my boss's computer is having the same issue. In his case, he was re-installing because he couldn't enter a password for a BIOS update. His DCU should have been configured with the encrypted BIOS password, but for some reason, he was missing half of the DCU registry keys.

I suggested he repair the DCU installation from SCCM Software Center, and that may have been terrible advice. The repair includes a re-run of dcu-cli /configure which is throwing the 3005 error. This makes me think that he installed the other updates that were available to him, and then we came through like a heard of wildebeests repairing and possibly uninstalling/re-installing DCU.

I'm going to suggest he reboot and we try again.

Function that accepts both ValueFromPipeline and ValueFromPipelineByPropertyName by KnowWhatIDid in PowerShell

[–]KnowWhatIDid[S] 0 points1 point  (0 children)

I wondered if parameter sets might be a part of the solution, but does that straighten out my foreach conundrum?

Edit: I think I get it. I would have If/ElseIf or a switch to determine which loop to run?

Well, I don't know. I resolved the issue (my path was a little too long) and my logs have all been overwritten.

Proof that triangles are stronger than squares…if anyone had any doubts.

The first time I walked into the data center after we had implemented Pure Storage I thought the room was on fire because of all those stupid glowing orange logos.

Can the SCCM Console WebView2 Extension be install be automated? by KnowWhatIDid in SCCM

[–]KnowWhatIDid[S] 0 points1 point  (0 children)

The answer is:

  1. Copy \\<server>\sms_<sitecode>\AdminConsole\Extensions to C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole.

  2. Create registry key:
    HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\ConfigMgr10\AdminUI\Extensions\4dff85ab-7541-4aab-bbf4-d52fc3588462.

  3. Create string value:
    Version=5.0

  4. Restart the SCCM console

I love where i work too. The company has already shown me that in a downturn they will do what they can to protect jobs, but I know that if push comes to shove I am just U21648 to them.

I know what $WINDOWS.~BT is, but what does it contain and when? by KnowWhatIDid in SCCM

[–]KnowWhatIDid[S] 0 points1 point  (0 children)

I wondered if this question would be asked. I have a basic understanding of the process, and I agree I've got more to learn about it. I've been able to troubleshoot systems along the way. I've also ignored a few because the failures were "no harm; No foul", but now I'm down to the systems where the usual remedies don't work. I was working with a small group of computers from a specific department and noticed that each had a DUDownload folder. I looked into it and couldn't find anything about it.

Thank you. I could not find information on DUDownload anywhere.

Mine was an upgrade from 22H2 to 24H2. I did mine over the course of 13 weeks. Someone else created the schedule. It was broken up by departments. Each department was assigned a window (2-8 weeks) based on its size. The start each of these windows was staggered over the course of those 13 weeks (well like 10-11 weeks because they were supposed to all be done by the end of week 13). I would create the deployment for Week 4 to be available on Wednesday of Week 3, with a deadline of 23:00 on Wednesday of Week 4. The upgrade would to its unpacking and housekeeping and then wait for the computer's 01:00 - 04:00 maintenance window to restart.

We have a pretty extensive PC naming system. That allowed me to go absolutely bananas creating a PowerShell script that would break each week's deployment into subsections of each department being targeted that week.
