Use this to limit the depth to 2:
<pre><code>Get-ChildItem \*\*\*,\*\*,\*
</code></pre>
The way it works is that it returns the children at each depth 2,1 and 0.
<hr />
Explanation:
This command
<pre><code>Get-ChildItem \*\*\*
</code></pre>
returns all items with a depth of two subfolders. Adding \* adds an additional subfolder to search in.
In line with the OP question, to limit a recursive search using get-childitem you are required to specify all the depths that can be searched.

I tried to limit Get-ChildItem recursion depth using Resolve-Path

<pre><code>$PATH = "."
$folder = get-item $PATH 
$FolderFullName = $Folder.FullName
$PATHs = Resolve-Path $FolderFullName\*\*\*\
$Folders = $PATHs | get-item | where {$_.PsIsContainer}

@scanlegentil I like this. 
A little improvement would be:

<pre><code>$Depth = 2
$Path = "."

$Levels = "\*" * $Depth
$Folder = Get-Item $Path
$FolderFullName = $Folder.FullName
Resolve-Path $FolderFullName$Levels | Get-Item | ? {$_.PsIsContainer} | Write-Host
</code></pre>

As mentioned, this would only scan the specified depth, so this modification is an improvement:

<pre><code>$StartLevel = 1 # 0 = include base folder, 1 = sub-folders only, 2 = start at 2nd level
$Depth = 2 # How many levels deep to scan
$Path = "." # starting path

For ($i=$StartLevel; $i -le $Depth; $i++) {
 $Levels = "\*" * $i
 (Resolve-Path $Path$Levels).ProviderPath | Get-Item | Where PsIsContainer |
 Select FullName
}
</code></pre>

<a href="https://msdn.microsoft.com/en-us/powershell/reference/5.0/microsoft.powershell.management/get-childitem">As of powershell 5.0</a>, you can now use the <code>-Depth</code> parameter in <code>Get-ChildItem</code>!

You combine it with <code>-Recurse</code> to limit the recursion.

I can get all sub-items recursively using this command:

<pre><code>Get-ChildItem -recurse
</code></pre>

But is there a way to limit the depth? If I only want to recurse one or two levels down for example?

Limit Get-ChildItem recursion depth

我可以使用以下命令递归地获取所有子项：Get-ChildItem -recurse但是有没有办法限制深度呢？例如，如果我只想向下递归一个或两个级别？
