Question

首先，我要道歉。我不与Powershell合作。这对我来说是一次很棒的学习经历！如果我的代码让你感到畏缩，我很抱歉：）

我在多个建筑物中工作，有时难以分辨用户的位置，搜索用户今天登录的位置会很好。

当用户登录以保存到文件时，我正在使用批处理脚本，以便在提交故障单时可以搜索它，但不包括计算机或甚至建筑物。每天都会自动生成一个新文件。

这是作为GPO绑定的登录批处理脚本：

 echo User: , %username% , Computer: , %computername% , Date\Time: , %date% %time% >> \\path\to\my\saved\file-%date:~-4,4%%date:~-10,2%%date:~-7,2%.csv

这是我用来搜索用户的powershell脚本：

Set-StrictMode -Version latest 

$path = '\\path\to\my\saved\'
$ext='.csv'
$file='file'
$realFile="$path$file-$(get-date -F 'yyyyMMdd')$ext"
$control = Read-Host -Prompt 'Which User are you looking for?'
$output = $path + "\output.log"
$CSV2String  = Select-String -Pattern $control -Path $realFile

Function getStringMatch 
{     
      $result = Select-String -Pattern $control -Path $realFile -Quiet 
      If ($result -eq $True) 
      { 
        $match = $realFile
        Clear-Host
        Write-Host "Success!  $control found logged in today!" -Foregroundcolor "green"
        ForEach ($line in $CSV2String) {  
        $text = $line -Split ","
        ForEach($string in $text) { 
        Write-Host "$string" 
            } 
        }
        Select-String -Pattern $control -Path $realFile | Out-File $output -Append 
      } ElseIf ($result -eq $False){
        Clear-Host
        Write-Host "Error $control not found logged in, please check the User Name and try again!" -ForegroundColor "red"
        Write-Host "'$control' Not logged in!" -ForegroundColor "yellow"
      } 
} 

getStringMatch

这看起来效果很好，但是当我使用脚本输出看起来很奇怪时，它会显示它搜索过的文件的路径，我不希望这样。我只想要输出信息。

Success!  SearchedUser found logged in today!
\\path\to\my\saved\file-20160209.csv:1:User:
 SearchedUser
 Computer:
 MyComputer-01
 Date\Time:
 Tue 02/09/2016  9:31:41.93

如何从输出中删除“\ path \ to \ my \ saved \ file-20160209.csv：1：”部分？我需要它根据当天的情况进行更改，如果可能的话我想使用变量。

我玩了-Replace，但我无法完成我想要的任务。

任何帮助将不胜感激：）

Answer 1

致电时：

$CSV2String  = Select-String -Pattern $control -Path $realFile

它返回一个MatchInfo对象数组。目前，您正在以MatchInfo的默认输出格式（包含MatchInfo属性的串联：Path：LineNumber：Line）调用Split。每个MatchInfo对象都有一个Line属性，该属性仅包含匹配的文本行。因此，您可以将代码更改为：

ForEach ($line in $CSV2String) 
{  
    $text = $line.Line -Split ","

Answer 2

不是答案，只是分享我完成的脚本，随心所欲地做它！

完成工作脚本：编辑略微更改为output.log我使它看起来与powershell输出相同，如果有人有更好的想法，我可能会再次更改它。 编辑2 在事故中遗漏了一些秘密信息;）
