Hi,

I have multiple batch files in a folder ,i want find out if batch A is running then batch B should not run and vice versa.

Any type of help will be appriciated.

Code: [Select]@echo off
setlocal

for /f %%i in ('tasklist /nh /FI "WINDOWTITLE EQ Command Prompt - BatchA" ^| find /i "cmd.exe"') do (
if errorlevel 1 (echo BatchA is NOT running
) else (echo BatchA is Running)
)

Good luck.

Try this more better code:

Code: [Select]@echo off

for /f %%i in ('tasklist /nh /fi "WINDOWTITLE eq Command Prompt - BatchA"') do (
echo %%i | find /i "cmd.exe" > nul
if errorlevel 1 (echo BatchA is NOT running
) else echo BatchA is running)
)

Thank you very much its working for.
but if BatchA is running then it should exit from BatchB and viceversa.
so it will be very helpful if you PROVIDE me that code.

e.g.

REM Batch A
if exist batchB.lock exit
echo abcde > batchA.lock
bla bla

bla bla
del batchA.lock

REM Batch B
if exist batchA.lock exit
echo abcde > batchB.lock
bla bla

bla bla
del batchB.lock
