不用ping .用%time% 比较精确

1. @echo off
   
2. set /a t=10,t1=0
   
3. :begin
   
4. set t0=%t1%
   
5. set tt=%time%
   
6. set t1=%tt:~6,2%
   
7. if %t1% neq %t0% (set/p=%t% <nul&set/a t-=1)
   
8. if %t% lss 0 (goto :eof)
   
9. goto :begin

我写的可能比较白一点

echo off
set a=10 9 8 7 6 5 4 3 2 1
for %%i in (%a%) do echo %%i
pause>nul.

@echo off
set a=11
:res
set /a a-=1
ping -n 2 127.0.0.1>nul>nul
cls
echo %a%
if %a% gtr 0 goto res
pause

新手，初来乍到，请多指教！
