下面的代码片段帮助您创建一个完整的路径。

Function GenerateFolder($path) {
    $global:foldPath = $null
    foreach($foldername in $path.split("\")) {
        $global:foldPath += ($foldername+"\")
        if (!(Test-Path $global:foldPath)){
            New-Item -ItemType Directory -Path $global:foldPath
            # Write-Host "$global:foldPath Folder Created Successfully"
        }
    }
}

上面的函数分割了传递给函数的路径，并将检查每个文件夹是否存在。如果它不存在，它将创建相应的文件夹，直到目标/最终文件夹创建。

要调用函数，使用下面的语句:

GenerateFolder "H:\Desktop\Nithesh\SrcFolder"

当指定-Force标志时，如果文件夹已经存在，PowerShell将不会报错。

一行程序:

Get-ChildItem D:\TopDirec\SubDirec\Project* | `
  %{ Get-ChildItem $_.FullName -Filter Revision* } | `
  %{ New-Item -ItemType Directory -Force -Path (Join-Path $_.FullName "Reports") }

顺便说一下，要调度任务，请查看这个链接:调度后台任务。

我知道用PowerShell创建目录有三种方法:

Method 1: PS C:\> New-Item -ItemType Directory -path "C:\livingston"

Method 2: PS C:\> [system.io.directory]::CreateDirectory("C:\livingston")

Method 3: PS C:\> md "C:\livingston"

试试-Force参数:

New-Item -ItemType Directory -Force -Path C:\Path\That\May\Or\May\Not\Exist

可以先使用Test-Path -PathType容器进行检查。

请参阅新项目MSDN帮助文章了解更多详细信息。

我希望能够方便地让用户为PowerShell创建一个默认配置文件来覆盖一些设置，并以以下一行程序结束(多个语句是可以的，但可以粘贴到PowerShell并立即执行，这是主要目标):

cls; [string]$filePath = $profile; [string]$fileContents = '<our standard settings>'; if(!(Test-Path $filePath)){md -Force ([System.IO.Path]::GetDirectoryName($filePath)) | Out-Null; $fileContents | sc $filePath; Write-Host 'File created!'; } else { Write-Warning 'File already exists!' };

为了可读性，以下是我在.ps1文件中如何做的:

cls; # Clear console to better notice the results
[string]$filePath = $profile; # Declared as string, to allow the use of texts without plings and still not fail.
[string]$fileContents = '<our standard settings>'; # Statements can now be written on individual lines, instead of semicolon separated.
if(!(Test-Path $filePath)) {
  New-Item -Force ([System.IO.Path]::GetDirectoryName($filePath)) | Out-Null; # Ignore output of creating directory
  $fileContents | Set-Content $filePath; # Creates a new file with the input
  Write-Host 'File created!';
}
else {
  Write-Warning "File already exists! To remove the file, run the command: Remove-Item $filePath";
};

$mWarningColor = 'Red'

<#
.SYNOPSIS
    Creates a new directory. 
.DESCRIPTION
    Creates a new directory. If the directory already exists, the directory will
    not be overwritten. Instead a warning message that the directory already
    exists will be output.
.OUTPUT
    If the directory already exists, the directory will not be overwritten.
    Instead a warning message that the directory already exists will be output.
.EXAMPLE    
    Sal-New-Directory -DirectoryPath '.\output'
#>
function Sal-New-Directory {
    param(
        [parameter(mandatory=$true)]
        [String]
        $DirectoryPath
    )
    $ErrorActionPreference = "Stop"
    try {
        if (!(Test-Path -Path $DirectoryPath -PathType Container)) {

            # Sal-New-Directory is not designed to take multiple 
            # directories. However, we use foreach to supress the native output
            # and substitute with a custom message.
            New-Item -Path $DirectoryPath -ItemType Container | `
              foreach {'Created ' + $_.FullName}
        } else {
            Write-Host "$DirectoryPath already exists and" `
                        "so will not be (re)created." `
                        -ForegroundColor $mWarningColor
        }
    } finally {
        $ErrorActionPreference = "Continue"
    }
}

“Sal”只是我自己的库的一个任意前缀。你可以移除它，或者用你自己的替换它。

另一个例子(放在这里，否则会破坏stackoverflow语法高亮显示):

Sal-New-Directory -DirectoryPath ($mCARootDir + "private\")
