Powershell – Recursively renaming files with Powershell

powershellrename

I currently have a line to batch rename files in a folder that I am currently in.

dir | foreach { move-item -literal $_ $_.name.replace(".mkv.mp4",".mp4") }

This code works perfectly for whatever directory I'm currently in, but what I want is to run a script from a parent folder which contains 11 child-folders. I can accomplish my task by navigating to each folder individually, but I'd rather run the script once and be done with it.

I tried the following:

get-childitem -recurse | foreach { move-item -literal $_ $_.name.replace(".mkv.mp4",".mp4") }

Can anyone please point me in the right direction here? I'm not very familiar with Powershell at all, but it suited my needs in this instance.
