Thanks KYHI,

I can find everything but the switch /c on the end of flushdns.. maybe that isn't a switch and does nothing..

for example

:Files
ipconfig /flushdns /c

I think that applies to cmd.exe when starting from a Run box normally:

/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains


cmd /c ipconfig /all opens a Command Prompt window, runs ipconfig /all then closes the window so you never see anything.
cmd /k ipconfig /all opens a Command Prompt window, runs ipconfig /all then leaves the window open so you can see the output.

cmd /? will get you some good info,

Code: 
Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.

C:\Users\Derek>cmd /?
Starts a new instance of the Windows command interpreter

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
    [[/S] [/C | /K] string]

[B][COLOR="#FF0000"]/C      Carries out the command specified by string and then terminates[/COLOR][/B]
/K      Carries out the command specified by string but remains
/S      Modifies the treatment of string after /C or /K (see below)
/Q      Turns echo off
/D      Disable execution of AutoRun commands from registry (see below)
/A      Causes the output of internal commands to a pipe or file to be ANSI
/U      Causes the output of internal commands to a pipe or file to be
        Unicode
/T:fg   Sets the foreground/background colors (see COLOR /? for more info)
/E:ON   Enable command extensions (see below)
/E:OFF  Disable command extensions (see below)
/F:ON   Enable file and directory name completion characters (see below)
/F:OFF  Disable file and directory name completion characters (see below)
/V:ON   Enable delayed environment variable expansion using ! as the
        delimiter. For example, /V:ON would allow !var! to expand the
        variable var at execution time.  The var syntax expands variables
        at input time, which is quite a different thing when inside of a FOR
        loop.
Press any key to continue . . .
