windows - Equivalent of Linux `touch` to create an empty file with PowerShell?

In PowerShell is there an equivalent of touch?

For instance in Linux I can create a new empty file by invoking:

touch filename

On Windows this is pretty awkward -- usually I just open a new instance of notepad and save an empty file.

So is there a programmatic way in PowerShell to do this?

I am not looking to exactly match behaviour of touch, but just to find the simplest possible equivalent for creating empty files.

Answer

Using the append redirector ">>" resolves the issue where an existing file is deleted:

echo $null >> filename
