Batch countdown but WITH showing countdown

I do know it can Batch timeout 30 etc but how to do showing countdown for

I saw here: http://www.trytoprogram.com/batch-file/shutdown-commands/ BOTTOM Page "Batch file program to shutdown, reboot, hibernate, and logoff the computer"

/t 0 is no good ever i did do /t 30 it not showing countdown

Any idea how to show the countdown like the: timeout 30 29 28 27 etc

Solution

A timer can be effected by using a for /L loop for the number of seconds, and a for /F loop executing a choice command with a /T 1 Delay with a /D default that performs no action.

Other options can be built into the For /F Choice loop to allow Cancellation of the shutdown, resetting of the countdown, or immediate shutdown:

 @Echo off
:Reset
 For /L %%i in (30 -1 1)Do (
  Cls
  Echo Shutting down in : %%i Seconds [C]ancel [S]hutdown Now [R]eset Timer
  For /F "Delims=" %%G in ('Choice /T 1 /N /C:CSRW /D W')Do (
   If %%G==R Goto :Reset
   If %%G==C Goto :Eof
   If %%G==S Shutdown /SG /T 0
  )
 )
 Shutdown /SG /T 1

EDIT:

Example of modifying the above for use as a function called from a menu.

@Echo off
:Menu
 Echo [E]xit [L]ogoff [R]estart [S]hutdown
 For /F "Delims=" %%G in ('Choice /N /C:SRLE')Do (
  If %%G==S Call :Timer "Shutdown /SG /T 1" "Shutting Down"
  If %%G==R Call :Timer "Shutdown /R /T 1" "Restarting"
  If %%G==L Call :Timer "Shutdown /L" "Logging Off"
  If %%G==E Exit /B
 )
:# On Cancel Command Selection:
Goto :Menu
:# Function With timer
:Timer [Command] [Prompt]
 For /L %%i in (30 -1 1)Do (
  Cls
  Echo %~2 in : %%i Seconds [C]ancel [R]estart Timer [N]o wait
  For /F "Delims=" %%G in ('Choice /T 1 /N /C:CRNW /D W')Do (
   If %%G==R Goto :Timer
   If %%G==C Goto :Eof
   If %%G==N %~1
  )
 )
 %~1
