Powershell 带打印输出的文本模式搜索
我是一名网络工程师,我编写了一个小型但有效的PS脚本来搜索日志(或任何相关文件)中的文本模式。现在这个脚本只输出行、文件名等。现在我想扩展脚本,这样当它找到一行时,它会告诉我行、文件名等等,还有那行的内容 所以它应该是这样的:Powershell 带打印输出的文本模式搜索,powershell,full-text-search,text-search,Powershell,Full Text Search,Text Search,我是一名网络工程师,我编写了一个小型但有效的PS脚本来搜索日志(或任何相关文件)中的文本模式。现在这个脚本只输出行、文件名等。现在我想扩展脚本,这样当它找到一行时,它会告诉我行、文件名等等,还有那行的内容 所以它应该是这样的: LineNumber Filename Path Pattern ---------- -------- -
LineNumber Filename Path Pattern
---------- -------- ---- -------
4 190719_Success.log C:\skripte\190719_Success.log test
.log第4行的文本应显示在此处
.log第5行的文本应显示在此处
抱歉格式化了,我希望你明白我的意思
由于我对PS脚本编写还比较陌生,我有点迷失了我应该如何实现这个目标,或者如果这是可能的话
这是我目前的代码:
Clear-Host
$Pfad = Read-Host "Bitte Pfad angeben" #Enter Directory Path to Search
$Suchbegriff = Read-Host "Suchbegriff eingeben" #Enter Pattern to search for
New-Item -ItemType directory -Path C:\Skripte -erroraction 'silentlycontinue' #create C:\Skripte Folder
Remove-Item -Path C:\Skripte\Suchergebnis.txt -erroraction 'silentlycontinue' #Cleanup from previous run
Remove-Item -Path C:\Skripte\Indizierung.csv -erroraction 'silentlycontinue' #Cleanup
cd $Pfad
echo $file.fullname
echo ""
select-string -Path .\*.* -Pattern "$Suchbegriff" -erroraction 'silentlycontinue' | Select-Object LineNumber,Filename,Path,Pattern | ft -wrap #Search the specified Directory
echo ""
while(($Create = Read-Host -Prompt "Unterordner durchsuchen? J für Ja, N für Nein") -ne "x") #Userinput if Subdirectorys should be searched aswell
{
switch ($Create)
{
'J'
{
Get-Childitem -erroraction 'silentlycontinue' | Get-ChildItem -Recurse -erroraction 'silentlycontinue' | Where-Object {$_.PSIsContainer} | Export-CSV -NoClobber -NoTypeInformation -Path C:\Skripte\Indizierung.csv #Get all Subdirectorys and put them in a CSV, two GCI are needed to reliably get all subdirectories.
$Files = import-csv -Delimiter ',' -Path C:\Skripte\Indizierung.csv #Import CSV
foreach ($File in $Files)
{
cd $file.fullname
echo $file.fullname
echo ""
select-string -Path .\*.* -Pattern "$Suchbegriff" -erroraction 'silentlycontinue' | Select-Object LineNumber,Filename,Path,Pattern | ft -wrap
echo ""
pause
exit
}
}
'n'
{
pause
Exit
}
}
}
看看下面的代码。我添加了一个用于处理文件的循环,并对输入和向控制台显示行内容的请求进行了一些验证 代码调整(@Theo:感谢您的输入)
先生,你真了不起。我已经试过了,到目前为止效果很好,但是是否可以立即检查文件而不是先收集?如果我想在exchange日志中搜索特定的文本,可能需要几天的时间才能运行,因为我测试过的exchange上大约有80.000个日志。您可以用
Get ChildItem | foreach Object-Process{}
循环替换foreach($Files中的File)
。因此,这些文件将被直接处理。请尝试修改我的脚本,如果您需要任何帮助,请告诉我们。Select String
有一个-Path
参数,因此您不需要先使用Get Content
。另外,我会在使用前使用searchpattern,尤其是因为用户可以键入任何内容,并且任何内容都可能包含regex-specialcharacters@Theo:当您直接使用-Path
参数时,是否有办法获取匹配行的内容?谢谢大家,我会试着自己修改它,然后进行修改,如果我有更多的问题,或者当我有新的草稿时,我会让你知道。
