如何在PowerShell中連接某些字串？-有解無憂

我正在創建一個 PowerShell 腳本，以根據一些 AD 資訊創建一個唯一 ID。這是我到目前為止所擁有的。

Import-Module -Name ActiveDirectory
$username = Read-Host -Prompt ("Please Enter the Username")
$startdate = Read-Host -Prompt ("Please Enter the user's Start Date (Format: Feb 2022 = 022022)")

基本上，我想創建另一個名為 $UserID 的變數，它將連接 Active Directory 用戶的給定名稱的第一個字母 Active Directory 用戶的姓氏的第一個字母，但小寫 $startdate。例如，如果我在 AD 中輸入 jdoe 作為 John Doe 的用戶名，并且 startdate 是 022022，那么 UserID 應該是 Jd022022。

有沒有辦法在 PowerShell 中連接它？

uj5u.com熱心網友回復：

您可以使用.tolower()和.Substring()方法來執行此操作。

Import-Module -Name ActiveDirectory
$username = Read-Host -Prompt ('Please Enter the Username')
$startdate = Read-Host -Prompt ("Please Enter the user's Start Date (Format: Feb 2022 = 022022)")
$user = Get-ADUser -Identity $username
$finalvariable = $user.GivenName.Substring(0,1)   $user.Surname.Substring(0,1).tolower()   $startdate
$finalvariable

您可以將其用作具有如下引數的可重用函式。

昵稱

  <#

  param
  (
    [Parameter(Mandatory = $true,
      ValueFromPipeline = $true,
      HelpMessage = 'Please Enter the Username')]
    [Object]$user, 

    [Parameter(Mandatory = $true,
      ValueFromPipeline = $true,
      HelpMessage = "Please Enter the user's Start Date (Format: Feb 2022 = 022022)")]
    [Object]$date
  )
  Import-Module -Name ActiveDirectory

  try {

    ## test if AD user exists
    $null = Get-ADUser -Identity $user
  }
  catch [Microsoft.ActiveDirectory.Management.ADIdentityNotFoundException] {
    ##can't find that user
    Write-Warning -Message 'There was an error finding that user.'
  }
  catch {
    ## a different issue 
    ## if you are seeing this you need to remove the
    ## "$null =" in the above try{} block
    Write-Warning -Message 'Other issues...'
  }
  finally {

    $inputuser = Get-ADUser -Identity $user
    $startdate = $date
    $output = $inputuser.GivenName.Substring(0, 1)   $inputuser.Surname.Substring(0, 1).tolower()   $startdate
    $inputuser = $null
    $user = $null
  }
  $output 
}
