File counting with Powershell commands
提问by Elmex
How can I count all files in a specific folder (and all subfolders) with the Powershellcommand Get-ChildItem?
With (Get-ChildItem <Folder> -recurse).Countalso the folders are counted and this is not that what I want. Are there other possibilities for counting files in very big folders quickly?
如何使用Powershell命令 Get-ChildItem计算特定文件夹（和所有子文件夹）中的所有文件？随着(Get-ChildItem <Folder> -recurse).Count也文件夹进行计数，这不正是我想要的。是否有其他可能性可以快速计算非常大的文件夹中的文件？
Does anybody know a short and good tutorial regarding the Windows Powerhell?
有人知道关于 Windows Powerhell 的简短而好的教程吗？

I would pipe the result to the Measure-Objectcmdlet. Using (...).Count can yield nothing in case there are no objects that match your criteria.
我会将结果通过管道传输到Measure-Objectcmdlet。如果没有符合您的条件的对象，则使用 (...).Count 不会产生任何结果。
$files = Get-ChildItem <Folder> -Recurse | Where-Object {!$_.PSIsContainer} | Measure-Object
$files.Count
In PowerShell v3 we can do the following to get files only:
在 PowerShell v3 中，我们可以执行以下操作来仅获取文件：
Get-ChildItem <Folder> -File -Recurse

Filter for files before counting:
计数前过滤文件：
(Get-ChildItem <Folder> -recurse | where-object {-not ($_.PSIsContainer)}).Count
