Question

How can I get all this to not only output on the screen, but to save to a text file in CSV format?

$OUs = Get-ADObject -LDAPFilter "(objectCategory=organizationalUnit)" `
     -SearchBase "OU=GA,OU=EAST,DC=corp,DC=chm,DC=com" | Select distinguishedName
 ForEach ($OU In $OUs)
 {
     $OU.distinguishedName
     Get-ADComputer -SearchBase $OU.distinguishedName -SearchScope OneLevel `
         -Filter * | Select Name
 }

I have tried

$OUs = Get-ADObject -LDAPFilter "(objectCategory=organizationalUnit)" `
     -SearchBase "OU=GA,OU=EAST,DC=corp,DC=chartercom,DC=com" | Select distinguishedName
 ForEach ($OU In $OUs)
 {
     $OU.distinguishedName
     Get-ADComputer -SearchBase $OU.distinguishedName -SearchScope OneLevel `
         -Filter * | Select Name
 } | | export-CSV c:\temp\outfile.csv –noType

And many other formats, but I always get the error:

An empty pipe element is not allowed.

Use the Tee-Object cmdlet.

The Tee-Object cmdlet enables you to display data in the Windows PowerShell window and to save that same data to a text file, all with a single command.

dir | Tee-Object -file dir.txt

You should use it like,

 ForEach ($OU In $OUs)
 {
     $OU.distinguishedName
     Get-ADComputer -SearchBase $OU.distinguishedName -SearchScope OneLevel `
         -Filter * | Select Name
 } | Tee-Object -file c:\temp\outfile.txt

Note: It has an alias, tee, which is the same as Unix’ tee.
