Difference action for different files - powershell

Question

I want to monitor new files created in a folder.
When this happens I want to launch a batch file (in the example below I just write a line in a log file).
I don't know why this doesn't work.
My code is:
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "D:\"
$watcher.Filter = "*.*"
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true
$action = {
$path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
$logline = "$(Get-Date), $changeType, $path"
if ($file.Name -like "Apertura") {
Add-Content "C:\Users\F701845\Desktop\Apertura.txt" -Value $logline
} else {
Add-Content "C:\Users\F701845\Desktop\TestNO.txt" -Value $logline
}
}
Register-ObjectEvent $watcher "Created" -Action $action
while ($true) {sleep 5}

Well this one is easy, you are using a variable that is empty in your IF/ELSE.
$path and $changeType are derived from $Event but $file is not existing at all.
First take a look at what you have and you will see that you might be able to use in this case: $Event.SourceEventArgs.Name.
$Event.SourceEventArgs | Get-Member
bool Equals(System.Object obj)
int GetHashCode()
type GetType()
string ToString()
System.IO.WatcherChangeTypes ChangeType {get;}
string FullPath {get;}
string Name {get;}
While it does work, it still looks for files called exactly Apertura meaning Apertura.txt wont work, i would recommend using something like Apertura.* if you do not know the extension.
Example Code:
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "C:\test\"
$watcher.Filter = "*.*"
$watcher.IncludeSubdirectories = $true
$watcher.EnableRaisingEvents = $true
$action = {
$path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
$file = $Event.SourceEventArgs.Name #get filename from Event data
$logline = "$(Get-Date), $changeType, $path"
if ($file -like "Apertura.*") { #removed the .Name and added .*
Add-Content "C:\Users\username\Desktop\Apertura.txt" -Value $logline
} else {
Add-Content "C:\Users\username\Desktop\TestNO.txt" -Value $logline
}
}
Register-ObjectEvent $watcher "Created" -Action $action
while ($true) {sleep 5}
$watcher.Dispose() #can be used to dispose the System.IO.FileSystemWatcher
