Powershelltesting如果文件夹为空

在Powershell中，如何testing一个目录是否为空？

Answer 1

尝试这个…

$directoryInfo = Get-ChildItem C:\temp | Measure-Object $directoryInfo.count #Returns the count of all of the files in the directory 

如果$directoryInfo.count -eq 0 ，那么你的目录是空的。

Answer 2

如果您对隐藏或系统文件不感兴趣，您也可以使用Test-Path

要查看它是否存在目录中的文件.\temp您可以使用：

 Test-Path -Path .\temp\* 

Answer 3

为了防止枚举c：\ Temp下的每个文件（这可能很耗时），我们可以这样做：

 if((Get-ChildItem c:\temp\ -force | Select-Object -First 1 | Measure-Object).Count -eq 0) { # folder is empty } 

Answer 4

 filter Test-DirectoryEmpty { [bool](Get-ChildItem $_\* -Force) } 

Answer 5

一条线：

 if( (Get-ChildItem C:\temp | Measure-Object).Count -eq 0) { #Folder Empty } 

Answer 6

只要添加到JPBlanc，如果目录path是$ DirPath，这个代码也适用于包括方括号字符的path。

  # Make square bracket non-wild card char with back ticks $DirPathDirty = $DirPath.Replace('[', '`[') $DirPathDirty = $DirPathDirty.Replace(']', '`]') if (Test-Path -Path "$DirPathDirty\*") { # Code for directory not empty } else { # Code for empty directory } 

Answer 7

获取所有文件和目录并仅计算它们以确定目录是否为空是很浪费的。 更好地使用.NET EnumerateFileSystemInfos

 $directory = Get-Item -Path "c:\temp" if (!($directory.EnumerateFileSystemInfos() | select -First 1)) { "empty" }

Answer 9

删除空文件夹的示例：

 IF ((Get-ChildItem "$env:SystemDrive\test" | Measure-Object).Count -eq 0) { remove-Item "$env:SystemDrive\test" -force } 

Answer 10

简单的方法

 if (-Not (Test-Path .\temp*) { #do your stuff here } 

你可以删除-Not如果你想要input“如果”文件时出现
