Powershell脚本过滤文件并使用奇偶数（从1到2）重命名文件]]

Posted 2023-02-28

[请在下面的脚本中查找，它的作用是找到* .txt文件，并使用filename.host1.txt或filename.host2.txt进行重命名。

我的要求是它应该以顺序模式创建，而不是随机创建（当前，它是作为随机基础而不是以顺序模式创建Host1或host2的，如果第一个文件将其重命名为file1.host1.txt，则第二个文件应该是file2.host2.txt，第三个文件将是file3.host3.txt，第四个文件将再次以file4.host1.txt，file5.host2.txt，file4.host3.txt开头。基本上从我想每当文件夹中检测到新文件时就将“ host1”添加到“ host3”，并以从1到3的顺序模式创建文件。 Host1，Host2，Host3我使用了三个虚拟机来执行sperete脚本。这是我的脚本。.

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
    $watcher = New-Object System.IO.FileSystemWatcher
    $watcher.Path = "C:\test"
    $watcher.Filter = "*.txt"
    $watcher.IncludeSubdirectories = $false
    $watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
    $action =  $path = $Event.SourceEventArgs.FullPath
                $filename = [io.path]::GetFileNameWithoutExtension($path)
                ###$changeType = $Event.SourceEventArgs.ChangeType
                ###$logline = "$(Get-Date), $changeType, $path, $filename"
                ###Add-content "D:\log.txt" -value $logline
                ###$proc=start-process "D:\source\$filename.bat" -Wait -NoNewWindow
                $script:counter++
                $hostname=""
                 if(($script:counter % 2) -eq 0)
                    $hostname="host1"
                 Else 
                    $hostname="host2"
                
                Rename-Item -Path "C:\test\$filename.txt" -NewName "$filename.$hostname.txt"
                  
### DECIDE WHICH EVENTS SHOULD BE WATCHED 
    Register-ObjectEvent $watcher "Created" -Action $action
 ###   Register-ObjectEvent $watcher "Changed" -Action $action
 ###   Register-ObjectEvent $watcher "Deleted" -Action $action
 ###   Register-ObjectEvent $watcher "Renamed" -Action $action

    while ($true) sleep 5

$counter = 1
while($True)
    Get-ChildItem -Path c:\test | ? $_.FullName -notlike "*.host*.txt" | Sort-Object -Property CreationTime | % 
        if($counter % 3 -eq 0)
            $hostSuffix = 3
        elseif($counter % 3 -eq  2)
            $hostSuffix = 2
        elseif($counter % 3 -eq  1)
            $hostSuffix = 1
        
        $counter++
        Rename-Item $_.FullName -NewName "$($_.BaseName).host$($hostSuffix).txt"
    
    sleep(4)
