Answer 1

Hi @Anonymous ,

I am not sure what is the expected outcome.

Maybe this helps:

$filepath = "Junk/someText.txt"  
$textToAdd = "Just a test with pipe"  
((Get-Content -Path $filepath)[$linenumber - 1]) + $textToAdd | Set-Content -Path $filepath

It's unlikely you'd be able to do what you want. Firstly because the file you're trying to modify would still be in use by the Get-Content cmdlet. Secondly because you'd have no idea how many lines are in the file until you reached the end.

Something like this might work for you:

$filepath = "c:\junk\cr.txt"
$textToAdd = "A","B"
$currentline = 0
[array]$fileContent = Get-Content $filePath
$lineNumber = $filecontent.count - 1
$filecontent |
    ForEach-Object{
        if ($currentline -eq $linenumber)
        {
            $textToAdd
        }
        $_
        $currentline++
    } | Set-Content $filePath
