使用PowerShell添加或删除文本文本

Question

我正在使用PowerShell添加或删除文件中的文本。我一直在我的文件中收到有趣的文字。

这只发生在我从文本文件中删除该行并且尝试添加新行时出现有趣的文本时。

cls 
IMPORT-MODULE ActiveDirectory 

$fileLocation = "E:\Script\MatchCadTest\ptc.opt"; 

function addUser($username=''){ 

    $user = Get-ADUser -Identity $username -ErrorAction SilentlyContinue; 
    $userFullName = $user.Name; 
    $empty = [string]::IsNullOrEmpty($userFullName); 

    if (!($empty)){ 
     $userExisted = Get-Content $fileLocation | Select-String "$username" -quiet 

     if(! $userExisted){ 
      $newLocation = "E:\Script\MatchCadTest\backup\"; 

      if((Test-Path -Path $fileLocation)) { 
       Copy-Item "$fileLocation" "$newLocation" 
      } 

      $date = Get-Date -Format "d-M-y Hms"; 
      $newName = "ptc_$date.opt" 
      Rename-Item "$newLocation\ptc.opt" $newName 

      # Add-Content $fileLocation "" 
      Add-Content -Path $fileLocation -Value "# $userFullName"; 
      Add-Content -Path $fileLocation -Value "INCLUDE MATHCAD USER $username"; 

      Write-Host "User has been added to file. Please restart the service." -BackgroundColor Green -ForegroundColor Black 
     } 
     else{ 
      Write-Host "User already existed" -BackgroundColor Red -ForegroundColor White 
     } 
    } 
} 

function removeUser($username=''){ 
    $user = Get-ADUser -Identity $username -ErrorAction SilentlyContinue; 
    # $user 
    $userFullName = $user.Name; 
    $empty = [string]::IsNullOrEmpty($userFullName); 

    if (!($empty)){ 
     $userExisted = Get-Content $fileLocation | Select-String "$username" -quiet 
     if($userExisted){ 
      $remove="# $userFullName"; 
      $removeUser = (Get-Content $fileLocation); 
      $removeUser | where {$_ -ne $remove}; 

      $remove="INCLUDE MATHCAD USER $username"; 
      $removeUser | where {$_ -ne $remove} 

      $removeUser |Out-File $fileLocation; 

      #$removeUser = (Get-Content $fileLocation) | where {$_ -ne $remove} | Out-File $fileLocation; 

      #$content = Get-Content $fileLocation 
      #$content | Foreach {$_.TrimEnd()} | Set-Content $fileLocation 

      Write-Host "User removed" -BackgroundColor Green -ForegroundColor Black 
     } 
     else{ 
      Write-Host "User does not existed" -BackgroundColor Red -ForegroundColor White 
     } 
    } 
    else{ 
     Write-Host "User not found in ad" -BackgroundColor Red -ForegroundColor White 
    } 
} 


$option='' 
while ($option -ne 0){ 

    Write-Host "What would you like to do?" 
    Write-Host "1= Add new user" 
    Write-Host "2= Remove user" 
    Write-Host "0= No (Exit)" 

    $option = Read-Host "Select option" 
    $username = Read-Host "Please enter Username" 
    if($option -eq 0){ 
     exit 1 
    } 

    elseif($option -eq 1){ 
     addUser($username); 
    } 
    elseif ($option -eq 22){ 
     removeUser ($username); 
    } 

    else{ 
     cls 
     Write-Host 
     Write-Host " Invaild Choice " -BackgroundColor Red #-ForegroundColor White 
     Write-Host 
    } 

    #Reset 
    $option=444; 
    $username=""; 
    $userFullName=""; 
    $user=""; 
    $empty=""; 
} 

当我删除文本从文件中的行，并添加新的用户，这都是一个有趣的文本字符串：

见下

‣潍慨浭摡䴠橡摩਍义䱃30⁅䅍䡔䅃/单剅洠ㅭ㘳㐰ല

我有一个包含以下信息的文本文件。

- // Full name 1 
- User ID of User 1 

- // Full name 2 
- User ID of User 2 

* // Full name 3 
* User ID of User 3 

* // Full name 4 
* User ID of User 4 

* // Full name 5 
* User ID of User 5 

* // Full name 6 
* User ID of User 6 

* // Full name 7 
* User ID of User 7 

* // Full name 8 
* User ID of User 8 

如果你看到用户5和6或7和8有额外的空间，我不会删除和广告只是sinlge空间。

我认为你需要设置编码为您Add-Content

尝试：Add-Content -Encoding UTF8 -Path $fileLocation -Value "# $userFullName";
