powershell - Add-Content - append to specific line

Question

I want to add text into specific line of txt file. I can't find any solution on internet.

This code adds text in further line (I want for example second line):

$test_out = "test"

$test_out | Add-Content "C:mpest.txt"

Answer 1

If you want to add text to the end of a specific line, you can do it like this

$fileContent = Get-Content $filePath
$fileContent[$lineNumber-1] += $textToAdd
$fileContent | Set-Content $filePath

If you want to replace the text instead of adding, just remove the '+' sign. You do of course have to set the variables $filePath, $textToAdd and $lineNumber first.
