Get-ADComputer -Filter \* -SearchBase "OU=Systems,OU=Alex,DC=com,DC=cn  
I can filter out all computer in the OU of Systems,

Get-ADComputer -Filter \* -SearchBase “OU=Systems,OU=Alex,DC=com,DC=cn” | foreach {Test-WSMan -ComputerName $\_.DNSHostName}  
Then I know which computer is online.

Then I want to use new-pssession to create a session for every online computer only.  
but how to do that in the pile after I test the computer. I want to complete my request in one line by using pile.  
I also want to add the DNSHostName to an additional text file for the on line computer by using \> textfile.txt after test-wsman  
any good idea ?

To test a connection you would normally use [Test-Connection](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/test-connection?view=powershell-7). 😉  
With that you can use an if statement to check the availability of the remote computers and when they are online you can use New-PSSession in your Foreach-Object loop.

BTW:When you post code, error messages, sample data or console output format it as code, please.  
In the “ **Text** ” view you can use the code tags “ **PRE** ”, in the “ **Visual** ” view you can use the format template “ **Preformatted** ”. You can go back edit your post and fix the formatting - you don’t have to create a new one.  
Thanks in advance.
