How do you append to a CSV file which already exists without overwriting the initial data? Essentially, I want to write PowerShell code to append data to an existing CSV file or a building a new CSV file without overwriting the existing data when an error is encountered. The code below continues to overwrite itself.
$Credentials = Get-Credential DOMAIN\USER_ID
$Servers = Get-Content .\Servers.txt
foreach ($ServerOccurrence in $Servers)
{
Try{
Get-WmiObject -Class Win32_Service -computername $ServerOccurrence -Credential $Credentials -ErrorAction Stop|Where-object {$_.name -like "Sym*"}|select-object -Property __server, name, startmode, startname, state, pathname | Export-Csv DRFT11-28-2012-V.Csv
-NotypeInformation
}
Catch{
Write-Host "Couldn't contact server " $ServerOccurrence -foregroundcolor green
Continue
}
}
However, if I run GET-WMIOBject command by itself, it seems to works fine. Let me know your thoughts
Get-WmiObject -Class Win32_Service -computername (Get-Content .\Servers.txt) -Credential DOMAIN\USER_ID -ErrorAction Stop|Where-object {$_.name -like "Sym*"}|select-object -Property __server, name, startmode, startname, state, pathname | Export-Csv DRFT11-28-2012-V.Csv -NotypeInformation
