![]() ![]() The script enters an infinite loop and periodically sleeps for 5 seconds, allowing the FileSystemWatcher to continue monitoring for file changes. If a file is found and its FullName is not equal to the value of $lastModifiedFile, the script block sets the $lastModifiedFile variable to the FullName of the found file and writes a message to the console indicating the name of the last modified file.įinally, the Register-ObjectEvent cmdlet is used to register the $changedAction script block as the action to be executed when the FileSystemWatcher detects a change in the monitored directory. The Select-Object cmdlet selects the first item in the sorted list. The $changedAction script block retrieves the most recently modified file in the directory using the Get-ChildItem cmdlet and sorting by the LastWriteTime property in descending order. The code then initializes a $lastModifiedFile variable to $null and defines a $changedAction script block that will be executed when a file change event is detected. The EnableRaisingEvents property is set to $true to enable the watcher to raise events when a change is detected. In addition, the $watcher.IncludeSubdirectories property is set to $false, which means that the watcher will only monitor the specified directory and not its subdirectories. The code creates a new instance of the System.IO.FileSystemWatcher class and sets its properties to monitor the C:\Test1 directory for any changes to any file using the *.* filter. Pause the script using Start-Sleep for a specified time (5 seconds) and continue monitoring the directory for changes.If the file meets the conditions in step 12, update the last modified file variable and write the file’s full name to the console.Check if the selected file is not null and if its full name is different from the last modified file.Sort the list of files by their LastWriteTime property in descending order.Use the Get-ChildItem cmdlet to retrieve the most recently modified file in the specified directory.Enter an infinite loop to keep the script running and waiting for events.Register the watcher object to listen for the Changed event and run the script block when the event occurs.Enable the watcher to raise events when changes occur in the specified directory.Set the IncludeSubdirectories property of the watcher to monitor only the specified directory, not the subdirectories.Set the Filter property of the watcher to monitor changes to all files in the directory.Set the Path property of the watcher to the directory( C:\Test1) to be monitored.Use New-Object to create a System.IO.FileSystemWatcher object to monitor a directory for file changes.To get last modified file in directory in PowerShell, use the FileSystemWatcher Class: By using the -newermt and ! options, you can easily search for files based on their modification time, making it a valuable tool for administrators and power users.Read more → Using the FileSystemWatcher Class ![]() In conclusion, the find command is a versatile and powerful tool that can be used to find files modified between two dates in Linux. You can also use the -exec option to run a command on each file found, such as copying the files to a different directory. For example, you can use the -ls option to list the details of each file found, including the size, permissions, and modification time. The find command also has a variety of other options that can be used to further refine your search. Note that the find command is case-sensitive, so be sure to use the correct capitalization when specifying the date. For example, if you wanted to find all files in the current directory and its subdirectories modified between January 1, 2023, and December 31, 2021, you would run the following command: find. Using these components, you can easily search for files modified between two dates. Again, the date must be in the format YYYY-MM-DD.
