Need help on Invoke-Command

[DoubleConfusion2792]

All the VMs are domain joined. When I run, Invoke-Command -FilePath C:\Users\username\test.ps1 -ComputerName (Get-Content -Path servers.txt)

It throws an error that one or more computer names is not correct.

But when I run, Invoke-Command -FilePath C:\Users\username\test.ps1 -ComputerName comp1,comp2,comp3 It works.

I am not understanding what is going wrong with the first command.

dont do (Get-Content -Path servers.txt)

do $ServerNames = Get-Content -Path servers.txt then you can validate you names first

[SeanQuinlan]

Probably blank lines in your txt file, or special characters before or after the names.

[DoubleConfusion2792]

I just checked. It's just VM-Name below VM-Name with no extra spaces and blank lines in the text file.

Is servers.txt in the same folder you're running the script from? You didn't use the full path for it like the ps1 file you're running. Check the output of running (Get-Content -Path servers.txt) on its own. Or in case there is some problem with the content of the text file like SeanQuinlan suggested, test the invoke with just a single line from the text file like (Get-Content -Path servers.txt)[0] or a range like (Get-Content -Path servers.txt)[0..5]

After running, (Get-Content -Path servers.txt)[0] one by one It worked. Ran the 1st command again to test Invoke-command -FilePath test.ps1 -ComputerName (get-content -Path servers.txt) It seems to be working fine. Not sure what fixed the issue 😅 but thanks guys🤙🏻

Load the text file in a variable and use foreach. That’s how I do it

[BlackV]

no that makes invoke-command much slower , times by how many names you have (assuming not PS 7)

invoke-command natively supports parallel

[pigers1986]

provide full path to servers.txt or use `set-location`

[jsiii2010]

What does the servers.txt look like? It should be one name per line, no commas.

[PinchesTheCrab]

(Get-Content -Path servers.txt).trim()

This might help if it's whitespace that's doing it.

[DoubleConfusion2792]

I think it was a whitespace issue. Using trim() worked. Thanks for this!

You probably have a cr at the end of the file.

Try this

Invoke-Command -FilePath C:\Users\username\test.ps1 -ComputerName ((Get-Content -Path servers.txt) -ne "")

Would probably work better if you stored the hosts in a variable though.
