the idea is to import a csv, and then if the value "infohostname" contains a nullorwithespace delete the entire line



    Function Last_NAS_Parse {

$Import_IP = Import-Csv -Path "$destination_RAW_NASaudit_nas_8_$((Get-Date).ToString('yyyy-MM-dd')).txt" -Header @("date","infohostname","Version","SMTP","Value_1","Value_2","Value_3","Value_4","Value_5","Value_6","Value_7","Value_8","Value_9")
$Import_IP | ForEach-Object {
if ( [string]::IsNullOrWhiteSpace($_.infohostname)


}


But don't know how can i delete the line after this is selected, thanks.

  • Firstly, your code is missing parentheses and brackets in order to compile as posted. Is your goal to delete the entire row from the file, or simply clear it?

IMO you don't need a function just a Where-Object:



$Header = ("date","infohostname","Version","SMTP","Value_1","Value_2","Value_3","Value_4","Value_5","Value_6","Value_7","Value_8","Value_9")
$Import_IP = Import-Csv -Path "$destination_RAW_NASaudit_nas_8_$((Get-Date).ToString('yyyy-MM-dd')).txt" -Header $Header |
Where-Object {![string]::IsNullOrWhiteSpace($_.infohostname)}


But of course you could wrap that in a function

(but a function without passed parameters and returned values isn't a real function)

    Loop over the results and store only objects where that boolean evaluation is true, and create a new file. In order to delete the row of the existing file, I believe you'd have to convert it to XLS/X and access it as a COM object



    $results = @()
    Function Last_NAS_Parse {

    $Import_IP = Import-Csv -Path C:pathtofile.csv
    $Import_IP | ForEach-Object {
    if ( [string]::IsNullOrWhiteSpace($_.infohostname))
    {
    Out-Null
    }
    else
    {
    $results += $_
    }
    }
    }

    Last_NAS_Parse
    $results | Export-CSV "C:exportpathofnewfile.csv"
