This is a simple utility to update the last write time on a file. Kind of like the 'touch' command on Unix.

Imports System.Runtime.InteropServices
Module touch
    Sub Main()
        If Command.Trim.Length = 0 Then
            Console.WriteLine("wintouch: Updates last modified time on selected file.")
            Console.WriteLine("Usage: wintouch ")
            Console.WriteLine()
        Else
            Try
                If System.IO.File.Exists(Command) Then
                    System.IO.File.SetLastWriteTime(Command, Now)
                    Console.WriteLine("wintouch: File touched successfully.")
                    Console.WriteLine()
                    System.Threading.Thread.Sleep(1000)
                Else
                    Console.WriteLine("wintouch: File does not exist: " & Command())
                    Console.WriteLine()
                End If
            Catch ex As Exception
                Console.WriteLine("wintouch: There was an error touching the selected file.")
                Console.WriteLine("Usage: wintouch ")
                Console.WriteLine("Error: " & ex.Message)
                Console.WriteLine()
            End Try
        End If
    End Sub
End Module
