Assorted NT/2000/XP/.. CMD.EXE Script Tricks
From the html version of the tscmd.zip 1cmdfaq.txt file
To the Description and the Index
 

This page is edited from the 1cmdfaq.txt faq-file contained in my tscmd.zip command line interface (CLI) collection. That zipped file has much additional material, including a number of detached .cmd script files. It is recommended that you also get the zipped version as a companion.

Please see "The Description and the Index page" for the conditions of usage and other such information.



52} How can I enter a password into a variable without echoing it?

This is a task that is best done with the help of Visual Basic program which the actual CMD script creates. Note that the resultant password variable is made available to the CMD script since this is a CMD, not a VBS FAQ.

  @echo off & setlocal enableextensions
  :: Build a Visual Basic Script
  set vbs_=%temp%\tmp$$$.vbs
  set skip=
  findstr "'%skip%VBS" "%~f0" > "%vbs_%"
  ::
  :: Prompting without linefeed as in Item #15

  echo.|set /p="Password: "
  :: Run the script with Microsoft Windows Script Host Version 5.6
  for /f "tokens=* delims=" %%a in ('
    cscript //nologo "%vbs_%"') do set MyPass1=%%a
  ::
  echo.
  echo.|set /p="Retype  : "
  for /f "tokens=* delims=" %%a in ('
    cscript //nologo "%vbs_%"') do set MyPass2=%%a
  ::
  :: Clean up

  for %%f in ("%vbs_%") do if exist %%f del %%f
  ::
  :: Demonstrate the result

  echo.
  if "%MyPass1%"=="%MyPass2%" (
    echo The entered password was %MyPass1%
    ) else (
    echo No match)
  endlocal & goto :EOF
  '
  'The Visual Basic Script

  Set WshPass = WScript.CreateObject("ScriptPW.Password") 'VBS
  Password=WshPass.GetPassWord() 'VBS
  WScript.Echo PassWord 'VBS

The output would be someting like
  C:\_D\TEST>cmdfaq
  Password:
  Retype  :
  The entered password was whatever

You might find also item #182 of interest.
