dir>nul 2>nul
Here, 2 refers to redirecting the standard error output to nul. I know, heh heh

Very careful, learned. Thank you!!!!!!!!!!!!

I've always been unable to understand, but finally got it. Thanks to the people before floor 33, especially lxmlxm!

It can be understood as >NUL shields the correct return information
2>NUL shields the information of wrong return

Learn another trick, thanks

Well written! Bits and pieces of learning...

Oh!
Suddenly see the light! ! ! !

If there are still any questions, take a look at this batch processing @echo off&mode con cols=80 lines=13&title,【%~n0】&setlocal,EnableDelayedExpansion&color 02
set a=To***:
set b=Distance doesn't mean separation, no contact doesn't mean forgetting, no phone calls don't mean neglect. Happy birthday to you, Merry Christmas, Happy New Year, always happy...
set c= ------ by ***
set d= 2007-3-16
echo/&echo\
for %%i in (a b c d) do (
set/p= <nul
for /l %%a in (0,1,100) do (
if not "!%%i:~%%a,1!"=="" (
if %%a==24 echo.&echo;
set/p= !%%i:~%%a,1!<nul
ping 127.1 -n 1 >nul
)
)
echo;&echo;
)
for /l %%i in (0x1,0x1,0x9) do (
set /a b=%%i ">>" 1
::call :modify %%i
set a=%%i
color !a!!b!
ping 127.1 -n 2 >nul)
ping 127.1 -n 3 >nul
goto :print
:end
echo.&echo.
ping 127.0.0.1 -n 7 >nul 2>nul
goto :eof

:print
cls&color 04&echo\&echo\&echo\&for /f "delims=" %%a in ('more +38 %0') do echo %%a
mshta vbscript:CreateObject("SAPI.SpVoice").Speak("Happy birthday to you!")(Window.close)
goto :end



iiiiiiiiiiiiiiiiiii Wish ***:

mshta vbscript:CreateObject("SAPI.SpVoice").Speak("Happy birthday to you!")(Window.close)

This sentence can make the batch processing sound, wonderful!

Learned something again today, not in vain. Hehe!

The speech rate is too fast, and the pronunciation is not quite right. It cannot pronounce pinyin,

Can the above deficiencies be solved?

Hope the expert can tell!

Learned something! Thanks to the expert!
