BAT file that can check a date

 Keywords:  DOS BAT DATE 

---

This DOS BAT file can test to see if a particular date has occurred yet or not. This could be used to enable or disable precesses on a certain date.

  REM  Hard parts by William Allen (NgReply@mayfly13.fsnet.co.uk)

  @ECHO OFF
  IF (GOTO:)==(%1) %1%2 (Subroutine handler)

  :: ECHO the check date here in YYYY/MM/DDb format:
  :: (This demo uses 15 May 2002=2002/O5/15b)
  ECHO.2002/05/15b>%TEMP%.\_CHECK

  :: Call Subroutine to return: C=Century Y=Year MO=Month D=Day
  CALL %0 GOTO: _DTM

  :: We then append the current date in same format+"a"
  ECHO.%C%%Y%/%MO%/%D%a>>%TEMP%.\_CHECK
  FOR %%V IN (C Y MO D) DO SET %%V=
  TYPE %TEMP%.\_CHECK| find /v /n "">%TEMP%.\_CHECK

  :: If current date has passed check date, this won't invert line order
  TYPE %TEMP%.\_CHECK|sort /+4|find /v /n ""|find "[1][2]">NUL
  DEL %TEMP%.\_CHECK
  IF ERRORLEVEL 1 GOTO PASSED
  ECHO. We haven't passed your check date yet
  GOTO EOF
