Please refer to the Microsoft’s reference documentation of the FileSystemWatcher class for the details. IncludeSubdirectory: extends the area of observation to the subdirectories of the specified path.Filter: a wildcard to define a subset of files to watch.NotifyFilter: what kind of change triggers an event (by default: LastWrite, FileName, DirectoryName).The command allows to specify the same parameters (with the same names) as if you are using the C# class directly. As an example, you can watch for changes in directory C:\Tempfiles. It hides the C#-API behind a PowerShell command with argument completion, it keeps track of the created watchers, and provides commands to pause notifications and to clean up the watchers if they are no longer needed.Īfter you install and import the module, you can create a new filesystem watcher. I made the FSWatcherEngineEvent PowerShell module to make these file system watchers easier to use.
#Filewatcher phpunit how to#
There are already many examples on the internet showing how to create and configure the watcher in PowerShell but this isn’t something I can easily recall from memory at the moment I need it. A file system watcher listens to change notifications generated by the operating system and invokes a given function if the file change matches several filter criteria like the directory, the file name or the type of the change. NET Framework class named FileSystemWatcher which suits this job perfectly.
Some time ago I wanted to sync files from a source directory to a destination directory immediately after they had changed in the source directory.
