powershell - 替换语句创建重复行

Question

我正在使用下面的代码

$content | ForEach-Object { 

$addresseeName = $_.Substring(11,50)            
$example = 'X' * 50                             
if ($_.Substring(0,10) -eq 'ADDRESSEE0')        
{ 
    $_ -replace $addresseeName, $example        

} 
else 
{ 
  $_ 
} 


$addresseeName2 = $_.Substring(62,50)           
$example = 'Y' * 50                             
if ($_.Substring(0,10) -eq 'ADDRESSEE0')        
{ 
    $_ -replace $addresseeName2, $example       
} 
else 
{ 
  $_ 
}

之前的文本文件:

ABSINVEST2|Y|N|

之后的文本文件:

ABSINVEST2|Y|N|

我正在尝试掩盖特定的字段(位置)。谁能为我解释为什么每个IF Else语句都重复该行？

更新我正在工作的代码:

$content | 
  ForEach-Object { 

  $addresseeName = $_.Substring(11,50)
  $addresseeName2 = $_.Substring(62,50)
  $example = 'X' * 50
    if ($_.Substring(0,10) -eq 'ADDRESSEE0')    


    { 
        $_.replace($addresseeName, $example).replace($addresseeName2, $example)
    } 

Answer 1

简短的答案是，因为您正在复制它(当前脚本将其输出两次)。尝试以下方法:

$content | ForEach-Object { 
    $addresseeName = $_.Substring(11,50)            
    $example = 'X' * 50                             

    if ($_.Substring(0,10) -eq 'ADDRESSEE0')        
    { 
        $_ = $_ -replace $addresseeName, $example        

    } 

    $addresseeName2 = $_.Substring(62,50)           
    $example = 'Y' * 50                             

    if ($_.Substring(0,10) -eq 'ADDRESSEE0')        
    { 
        $_ = $_ -replace $addresseeName2, $example       
    } 

    $_ 
}

通过在执行替换时将其设置为当前行变量 $_，然后仅在末尾仅输出一次(无论它是否已更改)来修改它。
