How to check and correct user input when he omit t

Question

I have this batch to kill some process typed of course by the user and it works 5/5 when the user for example typed Calc.exe with the extension, but my issue now is to improve this batch in order to add automatically with this program if the user has omitted to add extension .exe like Calc without extension .exe will not work.

@Echo off & cls
Mode con cols=72 lines=7
Set TmpFile=TmpFile.txt
Set Resultat=KillResult.txt
If Exist %TmpFile% Del %TmpFile%
If Exist %Resultat% Del %Resultat%

cls & color 0B
echo.
echo                Quel(s) processus voulez-vous fermer ?
echo.
set/p "process=Entrer le(s) nom(s) de(s) processus> "
cls & color 0C
Title Killing "%process%" ...
echo.
echo                       Killing "%process%" ...
echo.
echo %date% *** %time% >> %TmpFile%
For %%a in (%process%) Do Call :KillProcess %%a
Cmd /U /C Type %TmpFile% > %Resultat%
Start %Resultat%
echo.
Goto :Main
::*********************************************************************************************
:KillProcess
Taskkill /IM "%~1" /F >> %TmpFile% 2>&1
echo ***************************************************************************** >> %TmpFile% 
::*********************************************************************************************

So i'm focusing on this piece of code but no success ! this my little try :

:KillProcess
Set str=%~1
set str=%str:~-4%
echo.%str%
pause
if %str%==".exe" (Taskkill /IM "%~1" /F >> %TmpFile% 2>&1) || (Taskkill /IM "%~1.exe" /F >> %TmpFile% 2>&1)

So how to do that in batch ?

Thank you !

Answer 1

Something like

:loopMain
set /p "process=Entrer le(s) nom(s) de(s) processus> "
if "%process:.exe=%"=="%process%" goto :loopMain

or

:loopMain
set /p "process=Entrer le(s) nom(s) de(s) processus> "
if /I not "%process:~-4%"==".exe" goto :loopMain

or set "process=%process%.exe" instead of goto :loopMain.

Similar approach in case of multiple names typed in: check an correct user's input in a simple for %%a in (%process%) do ... loop.

Answer 3

If your files have never any other extension than .exe, you can use "%~n1.exe" to get the filename with .exe.

%~n1 is just the filename without extension. Than add .exe, and put quotes around it in case the filename contains a space.

But this will fail if your executable is example.program.exe, and the user entered example.program. In this case the result of "%~n1.exe" will be "example.exe". To avoid that, you have to check if the extension is .exe. You can use %~x1 to get just the extension.
