I have 2 csv files I'm asked to merge where the values from the first column match. Both files can have the possibility of having duplicate values, and if they do, a new row should be created to support those values. If no match is found, then print the value no match. Except for looking for duplicate values, I am using the following code... Function GetFirstColumnNameFromFile { Param ($CsvFileWithPath) $FirstFileFirstColumnTitle = ((Get-Content $CsvFileWithPath -TotalCount 2 | ConvertFrom-Csv).psobject.properties | ForEach-Object {$_.name})[0] Write-Output $FirstFileFirstColumnTitle }

I am running into an issue creating a Credential Object from an XML File on a remote server. Here is the code I am using to test XML File <Objs Version="1.1.0.1" xmlns="http://schemas.microsoft.com/powershell/2004/04"> <Obj RefId="0"> <TN RefId="0"> <T>Selected.System.Management.Automation.PSCredential</T> <T>System.Management.Automation.PSCustomObject</T> <T>System.Object</T> </TN> <MS> <S N="UserName">domain\username</S> <S N="Password"

I need to export registry keys from a remote computer for import into other remote machines (copy) using PowerShell V3.0. When I use REG QUERY to view the registry keys thus: reg query \\[computername]\HKLM\[subkey] /s | Out-File -append .\export.log all subkeys are recursively output to export.log as expected. However, when using REG SAVE to actually save a copy of the registry (in order to use REG RESTORE to import keys into target computers): reg save \\[computername]\HKLM\[subkey] .\export.hiv I am encountering the following error: "ERROR: The system was unable to find the specified

What it basically does is the script gets the .msu files from a location and copies to the "C:\temp\" folder. Then the script gets all the .msu files and stores the names in the array. Using the foreach loop it tries to apply the .msu updates to the local server where the script is running. However when i run the script. It doesn't do anything. Below is the code $from="sourceLocation\*.msu" $to="C:\temp\" Copy-Item $from $to -Recurse -Force $listOfMSUs= (Get-ChildItem –Path $to -Filter "*.msu").Name Write-Host $listOfMSUs if($listOfMSUs) { foreach($msu in $listOfMSUs) { Write-Host "Processing

Say you are scripting in Powershell 4.0 environment and you want to make sure the script works in Powershell 3.0. How do you ensure its backward compatible?. Ok the question as phrased is a little more specific into what you are looking for. Sounds like you are asking for requires . The #Requires statement prevents a script from running unless the Windows PowerShell version , modules, snap-ins, and module and snap-in version prerequisites are met. If the prerequisites are not met, Windows PowerShell does not run the script. That way, while you are scripting, you can enforce the functional

I have 200 PC that need to have some specific icons removed. I created a CSV file with the ComputerName (1 name per row) I have another file with the file name of the icon that needs to be removed from the desktops (Shortcut1.lnk, etc). This other file is also a CSV (1 file name per row). How can I run a PowerShell script to remove those icons. (Please note that not all computers in my CSV file maybe turned on. Some maybe off or have network issues). $SOURCE = "C:\powershell\shortcuts" $DESTINATION = "c$\Documents and Settings\All Users\Desktop" $LOG = "C:\powershell\logs\logsremote_copy.log"
