Question

How can I pre pend (insert at beginning of file) a file to all files of a type in folder and sub-folders using Powershell?

I need to add a standard header file to all .cs and was trying to use Powershell to do so, but while I was able to append it in a few lines of code I was stuck when trying to pre-pend it.

Here is a very simple example to show you one of the ways it could be done.

$Content = 'This is your content`n' Get-ChildItem *.cs | foreach-object {  $FileContents = Get-Content -Path $_ Set-Content -Path $_ -Value ($Content + $FileContents) }
