I need to write a batch file that CHECKS to see if a process is running, and then either kill it or close itself depending on if it is running.

Not just once though, say I have 10 Firefox's up, I would want it to close one, and then check, close, check, etc. until they are all closed, and then close itself.

Even though I don't know the actual commands and how the errorlevels read, I would think it would look something like this:

@echo off
:START
check firefox.exe
if ERRORLEVEL ==2 goto END
if errorlevel ==1 goto KILL
:KILL
taskkill /f /im firefox.exe
goto START
:END

Any suggestions are appreciated!taskill /f /im [imagename] kills all instances of imagename. So you would only need to run it once.

Code: [Select]@echo off
REM start 10 notepads
echo Starting 10 notepads...
for /L %%N in (1,1,10) do start /MIN "" "notepad"

echo Press a key to stop them all...
pause>nul

REM kill them all
taskkill /f /im "notepad.exe"


Code: [Select]Starting 10 notepads...
Press a key to stop them all...
SUCCESS: The process "notepad.exe" with PID 2208 has been terminated.
SUCCESS: The process "notepad.exe" with PID 1308 has been terminated.
SUCCESS: The process "notepad.exe" with PID 3480 has been terminated.
SUCCESS: The process "notepad.exe" with PID 1548 has been terminated.

SUCCESS: The process "notepad.exe" with PID 3528 has been terminated.
SUCCESS: The process "notepad.exe" with PID 1340 has been terminated.:O! You're right, I forgot it did it for all instances, but still.. say I wanted it to check to see if an .exe is running, and then open it if it isn't? Kinda the opposite, but I kinda wanna know how it works both ways. Code: [Select]tasklist /fi "imagename eq notepad.exe" /fi "status eq running" | find "No tasks are running which match the specified CRITERIA">nul
if %errorlevel% equ 0 start notepad.exe
Gunna go give it a whirl!

Edit: It opened another even if the first is still running. D:Quote from: JooseyJay on July 04, 2010, 05:58:30 AM
