In PowerShell, the Get-ChildItem cmdlet works like ls (at least with the file system provider). All items returned have a PowerShell-specific property called PSIsContainer, indicating whether it's a directory or not:

foreach($item in (Get-ChildItem)){
    if($item.PSIsContainer){
        "Directory"
    } else {
        "File"
    }
}

If you want to see what's inside each directory, one level down:

foreach($item in (Get-ChildItem)){
    if($item.PSIsContainer){
        # Directory! Let's see what's inside:
        Get-ChildItem -Path $item.FullName
    }
}

As of PowerShell version 3.0 and up, the Get-ChildItem supports a File and Directory switch on the filesystem provider, so if you ONLY want directories, you could do:

Get-ChildItem -Directory

So the second example becomes: 

Get-ChildItem -Directory | Get-ChildItem

You could also list files recursively (like ls -R):

Get-ChildItem -Recurse

A more PoSh way is to use a pipeline, and perhaps a hashtable:

$type = @{
  $true  = 'Directory'
  $false = 'File'
}

Get-ChildItem | ForEach-Object { $type[$_.PSIsContainer] }

PowerShell even has a default alias ls for Get-ChildItem, so you could use more Unix-ish syntax:

ls | % { $type[$_.PSIsContainer] }
