![]() ![]() The neat thing is that because I do know Windows PowerShell so well, I can compensate. OK, so maybe I am not the world’s greatest computer user, but I know Windows PowerShell really well. Use Windows PowerShell to find files by date ![]() After spending 15 minutes attempting to browse and search for these files, I finally gave up. In fact, I spent each day teaching the class, the evenings with friends, and the nights writing new labs for the coming day’s class. When the Scripting Wife and I were in Montreal, Canada last October, I remember writing some additional Windows PowerShell labs for the class. However, one thing I have not figured out used to be very easy in the Windows 95 days by using the old-fashioned Find utility-that is to find a file by date. I modified the indexing to include the full contents of my Windows PowerShell script files, and it works great. At times, I will ask her to find something that I have wasted 15 minutes seeking, and she can find it almost immediately.Ī case-in-point is Windows Search. In my office, often the Scripting Wife sits beside me and does whatever she does. In fact, when it comes to finding things on the Internet, the Scripting Wife often is faster than I am. I am not the best computer user in the world. Microsoft Scripting Guy, Ed Wilson, is here. Save my name, email, and website in this browser for the next time I comment.Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to find files modified by month and year. Your email address will not be published. That’s all about PowerShell get last modified file in directory. The method you choose depends on your personal preferences. The script will run indefinitely until it is manually stopped by pressing Ctrl+ C.Ĭonsidering the above solutions, multiple methods exist for getting the last modified file in a directory using PowerShell. 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: Read more → Using the FileSystemWatcher Class ![]()
