Need output results piped out to file [pre] PS C:\WINDOWS\system32\> $results = invoke-command -computer TGCS001-2012R2 -scriptblock {reg delete “HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f} PS C:\WINDOWS\system32\> $results = invoke-command -computer TGCS001-2012R2 -scriptblock {(Get-ItemProperty -Path ‘Registry::HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations} Property PendingFileRenameOperations does not exist at path HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager. - CategoryInfo : InvalidArgument: (PendingFileRenameOperations:String) [Get-ItemProperty], PSArgumentException - FullyQualifiedErrorId : System.Management.Automation.PSArgumentException,Microsoft.PowerShell.Commands.GetItemPropertyCommand - PSComputerName : TGCS001-2012R2   PS C:\WINDOWS\system32\> $results The operation completed successfully. [/pre] As you can see the first command places results in $Results. The second command places results to console How do I get the results to be added to $results I tried +=   Any ideas?   Thank you   Tom         ---

After the first command, $result isn’t an array, so you can’t add to it that way. ``` [array]$results += ``` ---

JS [pre] try { [array] $results = invoke-command -computer TGCS001-2012R2 -scriptblock {reg delete “HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f} } catch { [array] $results += invoke-command -computer TGCS001-2012R2 -scriptblock {(Get-ItemProperty -Path ‘Registry::HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations} } Added the array and when it errors I do not get anything in $results I added the try catch If line 1 has a value I need line 2 to run if line one is not present no need to run line two.   Any ideas?       [/pre] ---

You have to handle the error. First of all, writing through mobile, so unable to design well. But can guide you the concept. [pre] try { $result += 1st statement -ea stop $result += 2nd statement -ea stop } Catch { $result += $\_.exception.message} [/pre] So, successful statement saves its output through try block and failed statement will do the same through catch block. Let me know your result. ---

Sankhadip Roy Thank you that seems to work out How can I add the computer name to the $Results I tried this with no luck   [pre] try { $results = invoke-command -computer TGCS001-2012R2 -scriptblock {reg delete “HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f} -ea Stop $results += invoke-command -computer TGCS001-2012R2 -scriptblock {(Get-ItemProperty -Path ‘Registry::HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations} -ea Stop $Results += ‘Server TGCS001-2012R2’ } catch { $Results += $\_.exception.message} [/pre] PS C:\WINDOWS\system32\> $results ERROR: The system was unable to find the specified registry key or value.   Would like $results to show Server = TGCS001-2012R2 ERROR: The system was unable to find the specified registry key or value. Any ideas? Thanks Tom       ---

Guys Got a little further [pre] $Results += ‘Server TGCS001-2012R2’ | out-string try { $results += invoke-command -computer TGCS001-2012R2 -scriptblock {reg delete “HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f} -ea Stop $results += invoke-command -computer TGCS001-2012R2 -scriptblock {(Get-ItemProperty -Path ‘Registry::HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations} -ea Stop } catch { $Results += $\_.exception.message} $Results += ‘Server TGCS002-2016’ | out-string try { $results += invoke-command -computer [TGCS002-2016.home.tgcsnet.com](http://TGCS002-2016.home.tgcsnet.com) -scriptblock {reg delete “HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager” /v PendingFileRenameOperations /f} -ea Stop $results += invoke-command -computer [TGCS002-2016.home.tgcsnet.com](http://TGCS002-2016.home.tgcsnet.com) -scriptblock {(Get-ItemProperty -Path ‘Registry::HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager’ -Name PendingFileRenameOperations ).PendingFileRenameOperations} -ea Stop } catch { $Results += $\_.exception.message} [/pre]   The output looks like this PS C:\WINDOWS\system32\> $results Server TGCS001-2012R2 ERROR: The system was unable to find the specified registry key or value.Server TGCS002-2016 ERROR: The system was unable to find the specified registry key or value.   How can I get the second, third forth etc computers on a separate line Server TGCS001-2012R2 ERROR: The system was unable to find the specified registry key or value. Server TGCS002-2016 ERROR: The system was unable to find the specified registry key or value. A blank line between each computer would be nice also.       ---
