   The following adds day-of-week to the default output of DIR in   
   my Windows 7.  Some additional arguments, e.g. /L, can be used.   
   ISO 8601 date/times have been assumed; other formats may work.   
   Adjustments may be needed if the OS is localised foreign.   
      
   // PLUS-DOW.JS Add day-of-week to output of DIR, piped I/O   
   // (c) JRS 2018-08-20+   
   // PLUS-DOW.BAT holds :   
   //  @DIR /o:d %* | CSCRIPT //nologo C:\UTYS\PLUS-DOW.JS   
      
   function AddDoW(match) { return match + " " +   
       new Date(match.replace(/-/g, "/")).toString().substring(0, 3) }   
      
   var stdin = WScript.StdIn   
   var stdout = WScript.StdOut   
   var Str, RE = /(\d\d.+:\d\d )/   
      
   while (!stdin.AtEndOfStream) {   
     Str = stdin.ReadLine()   
     if (RE.test(Str)) {   
       Str = Str.replace(RE, AddDoW)   
       stdout.WriteLine("  " + Str) } }   
      
   // End.  E&OE.
