Powershell loop through folders, create file in each folder

Question

I'm trying to recursively loop through all the folders in a directory, then do something within each directory. Create a text file, for example.

I can get all the subfolder into a variable like so:

$folders = Get-ChildItem -Recurse | ?{ $_.PSIsContainer }

However, I can't seem to create a file within each subdirectory - the files are instead created in the top directory. This doesn't work:

$folders | ForEach-Object { New-Item -ItemType file -Name "$_.txt" -path $_}

That throws up an error that the directory is not found or that the path is too long.

How do I do something in each subdirectory of nested folders?

Answer 1

Try this:

Get-ChildItem -Recurse -Directory | ForEach-Object {New-Item -ItemType file -Path "$($_.FullName)" -Name "$($_.Name).txt" }

Basically, the Get-ChildItem command returns a sequence of DirectoryInfo objects. The FullName property contains the full path, whilst Name just contains the name of the leaf directory.
