How to extrat/sort/output data from a power shell variable

Chris Huang 1 Reputation point

Hi team,

I am new to powershell. Some help please.

I am trying to get a list of hostname from an OU which contains only computer object, I would like to sort the rows of hostname and only output a smaller list of hostname which contains certain keywords (Sales_PC1, Sales_PC2 etc...) to a txt file.

$PCList = Get-ADComputer -SearchBase 'OU=MyComputerOU, dc=contoso, dc=co, dc=nz' -Filter '*' |Select -Expand Name

The above command returns all the computer objects that are sitting in the "MyComputerOU".

What PowerShell command should I use to extract data from the variable $PCList and output it to a txt file?

Your help would be much appreciated.

    A slight modification of the example posted by @Andreas Baumgarten .

    There's no need to create an intermediate array (i.e. the variable $PCLIST), and the -Filter can be adjusted to replace the need for the Where-Object.

    Get-ADComputer -SearchBase 'OU=MyComputerOU, dc=contoso, dc=co, dc=nz' -Filter "name -like 'sales*'" |  
        Select-Object -Expand Name |   
            Sort-Object |  
                Out-File -FilePath TestComputer.txt  

    Because you're "new to PowerShell" there are quite a few instructional articles, demonstrations, etc. to e found on the web. But probably the best place to start would be with this book (it's a free PDF download): Windows-PowerShell-4

    Ignore the fact that it's PowerShell version 4. There are only trifling differences between that version and 5.1. Oh, and just ignore the advertisements and praise for Sapien found throughout the book. Sapien's a company that makes good products, but you don't need them now (and you may never need them).

    Get yourself a good editor (VS Code and Virtual Studio are both free) and install the necessary addons to make coding PowerShell a lot easier. You won't regret it.

    Hi @Chris Huang ,

    you can try this (Filter on all lines with Sales):

    $PCList = Get-ADComputer -SearchBase 'OU=MyComputerOU, dc=contoso, dc=co, dc=nz' -Filter '*' |Select -Expand Name  
    $PCList | Where-Object {$_ -match "Sales"} | Out-File -FilePath "TestComputer.txt"
