Remember there is a command to delete the batch file itself, but I forgot it for a moment. For example: What command can be used in A.BAT to delete A.BAT itself?

@echo off
echo Before delete:
dir %0.*
echo Going for delete myself...
echo %0 | find /i ".bat"
if errorlevel 1 goto _addext
copy %0 %0.bak > nul
del %0
goto _quit:_addext
copy /y %0.bat %0.bat.bak > nul
del %0.bat:_quit

Here is the speech of Climbing quoted on 2004-11-26 13:21:37:

@echo off
echo Before delete:
dir %0.*
echo Going for delete myself...
echo %0 | find /i ".bat"
if errorlevel 1 goto _addext
copy %0 %0.bak > nul
del %0
goto _quit
:_addext
copy /y %0.bat %0.bat.bak > nul
del %0.bat
:_quit

Can just `del /q a.bat` work?

What if the batch file is not called A.bat? My batch file is for any file name (of course, the extension must be BAT). The problem the owner put forward is to let the batch file delete itself, and it is not limited that this batch file must be called A.BAT, so we need to judge what its own name is from inside the batch file.

del /q %0 can delete itself.

Re Climbing:
Modify your program slightly. Also, there is still a prompt that the batch file cannot be found, and the temporary deletion program will also leave a tail, so it is still necessary to use the system's uninstall mechanism, but the program will be complicated.
Re linson:
The del /q %0 statement cannot delete itself when the main program name is used to call the batch program in the command line.
@echo off
echo Before delete:
dir %0.*
echo Going for delete myself...
::echo %0 | find /i ".bat"
::if errorlevel 1 goto _addext
if exist %0.bat goto _addext
if not exist %0 goto _quit
copy %0 %0.bak > nul
del %0
goto _quit
:_addext
copy /y %0.bat %0.bat.bak > nul
del %0.bat
:_quit
