Powershell脚本无法将ForEach-Object识别为有效的cmdlet

Question

我已经编写了一个powershell脚本来对Active Directory进行修改。 我得到一个有趣的错误。 这是脚本。

#imports the module active directory if it isn't there. 
function add-ADmodule() 
      { 
      $modules = Get-Module | Where-Object{$_.Name -like "*ActiveDirectory*"} 

      if($modules -eq $null) 
       { 
       Import-Module ActiveDirectory 
       } 
      } 

#import the data file 
$user_csv = import-csv C:\temp\users.csv 

#makes the ammendments to the AD object 
function ammend-ADUsers($user_csv) 
    {#this is the loop to make ammendments to each object 
     $users_csv|ForEach-Object` 
       { 
       #assigns each user's AD object to a variable 
       $user_object = get-aduser -filter * ` 
              -Properties mail |` 
           Where-Object{$_.mail -like $_."Email Address"} 

       #ammends the ad object in the above variable 
       set-aduser -Identity $user_object ` 
          -OfficePhone $_."Office Number" ` 
          -MobilePhone $_."Mobile Number" ` 
          -StreetAddress $_."Street" ` 
          -City $_."City" ` 
          -PostalCode $_."PostCode"  
       } 
    } 


#this is the main part of the code where it gets executed 

add-ADmodule 
Write-Verbose "Active Directory Module Added" 

ammend-ADUsers($user_csv) 

这是我得到的错误。

我不知道什么可能导致此错误或为什么发生。

你的问题，是因为你还没有把cmdlet和反引号字符之间的空间，但它会更好，不使用反引号，而是只保留在同一行大括号{：

$users_csv|ForEach-Object { 

你也不需要管道角色后面的倒钩。您可能还想考虑使用splatting而不是反引号来改进您的格式（反引号通常是不鼓励的，因为它们很难被看到并且不便于使用）。我建议以下修订：

$users_csv | ForEach-Object { 
     #assigns each user's AD object to a variable 
     $user_object = Get-ADUser -filter * -Properties mail | 
         Where-Object{$_.mail -like $_."Email Address"} 

     $Props = @{ 
      Identity = $user_object 
      OfficePhone = $_."Office Number" 
      MobilePhone = $_."Mobile Number" 
      StreetAddress = $_."Street" 
      City = $_."City" 
      PostalCode = $_."PostCode"  
     } 
     #ammends the ad object in the above variable 
     Set-ADUser @Props 
    }
