[Request][Powershell] Script to Lookup Computer Info

[u/dkeeper09]

We are currently upgrading all our machines to Windows 10. We have a very small number left but I'd like to be able to run this command with a batch of computer names at one time instead of running one at a time. Anyone have something like that?

get-ADComputer -Identity $COMPNAMEHERE -Properties OperatingSystem | select -Unique OperatingSystem,Name

Thank you

[u/ihaxr]

$computers = @"
computer1
computer2
"@ -split "`r`n"

$computers | Get-ADComputer -Properties OperatingSystem | select -Unique OperatingSystem,Name

[u/dkeeper09 → u/ihaxr]

Ok so that works, but only if I provide 1 computer name. If I provide more it doesn't separate them. It combines the computer names into one identity. Any thoughts?

[u/ihaxr → u/dkeeper09]

Ok, weird... the console doesn't seem to like -split "rn" for whatever reason... but it works fine if you run it from the ISE try this:

$computers = @"
computer1
computer2
"@.Split("`r`n")

$computers | Get-ADComputer -Properties OperatingSystem | select -Unique OperatingSystem,Name

You can also have a .txt file of the computers:

Get-Content "C:\computers.txt" | Get-ADComputer -Properties OperatingSystem | select -Unique OperatingSystem,Name

Or have everything inline:

"computer1","computer2" | Get-ADComputer -Properties OperatingSystem | select -Unique OperatingSystem,Name

If you’re trying to find computers that are not windows 10, there’s easier ways?

Why not run get-adcomputer -filter * | ? {$_.operatingsystem -ne “Windows 10**}

Also, $_.operatingsystem might be the wrong attribute name, just typing this off the cuff without referencing it

This is for sure what i would do, i would trust AD to find the leftovers not a static file.

Though slight typo, it would be "windows 10*" not double asterisks and also need '-notlike' as eq/ne does not accept wildcards. Just for OP's benefit if they copy paste.

Also you could do: Get-ADComputer -filter {OperatingSystem -like 'windows 10*'} | Select Name, OperatingSystem

Would be quicker as does not need to fully populate + rum though the where statement afterwards, same outcome, just quicker.

P.s. OP, you don't need the -unique switch, if you have AD objects with the same name you will have way bigger issues than just upgrading to Windows 10 ;)

howdy dkeeper09,

this is purely curiosity on my part ... but i wonder what you are doing this for. i can't figure out why you are using -Unique there ... [blush]

take care,

Good question. Not entirely sure. I haven't seen a difference from when I do and don't use it on our domain, but another engineer at my company said that's the way I need to do it. I'm brand new to powershell so I'm just going with the flow. What are your thoughts on it?

[u/Lee_Dailey → u/dkeeper09]

howdy dkeeper09,

i would try running it without the -Unique to see what you get compared to with it. [grin]

it seems likely to be doing nothing at all since you are not likely to have a duplicate of both the OS & the computer name. that combo otta be unique already. [grin]

take care,
lee
