利用powershell监控文件夹变动

利用powershell监控某个文件夹下面的文件变化

### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "D:\" #监控路径
$watcher.Filter = "*.*" #监控文件类型
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true  

### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
$action = { $path = $Event.SourceEventArgs.FullPath
    $changeType = $Event.SourceEventArgs.ChangeType
    $logline = "$(Get-Date), $changeType, $path"
    Add-content "E:\文件监测\log.txt" -value $logline #日志文件
}    
### 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 }
