Detect if a process exists and take a predefined action.

tasklist /nh>d:\tddown~1\1.txt find /i "QQ.exe" d:\tddown~1\1.txt if ERRORLEVEL 1 (echo qq.exe does not exist) else (echo qq.ex exists)------------Second-----------
tasklist /nh|find /i "QQa.exe" if ERRORLEVEL 1 (echo qqa.exe does not exist) else (echo qqa.exe exists)



Check if there is a QQ.EXE process on the computer, and if so, automatically end it
http://www.cn-dos.net/forum/viewthread.php?tid=37918

a) First, use tasklist to input the process list to find, let find find the qq.exe process. If found, then perform the following end operation; if not found, exit the bat

@echo off tasklist|find /i "qq.exe" ||exit taskkill /im qq.exe /f

b) Put the process list in document A and then use the FIND search code:

@echo off tasklist>C:\a.txt find "QQ.exe" C:\a.txt&&taskkill /f /im "QQ.exe"

c) If it is not a cyclic monitoring, directly taskkill... Anyway, the final purpose is to not have the QQ process.


Automatically detect the process list every 20 seconds and automatically close notepad.exe.

@echo off :1 tasklist | find "notepad.exe" >>c:\notepad.luowei if exist c:\notepad.luowei taskkill /f /im notepad.exe ping 127.1 -n 20 >nul 2>nul goto 1


Detect explorer.exe process
http://www.cn-dos.net/forum/viewthread.php?tid=36526
Detect the explorer.exe process. If this process is found, exit; if not, copy one from the E drive to the system directory and then run it.
My system often can't enter, and I find that the explorer.exe file is deleted by the virus.

tasklist|find /i "explorer.exe"||copy /y e:\drivers\explorer.exe %systemroot%\&&start /b explorer.exe


Detect the running of a process every 30 seconds, and if it does not exist, restart the computer.
http://www.cn-dos.net/forum/viewthread.php?tid=31759

@echo off rem Restart should use -r tasklist|findstr /i "explorer.exe" ||shutdown -r -t 50 rem Bamboo said that the first message of ping does not need to wait, so the delay of 30 seconds should use -n 31 ping 127.1 -n 31 >nul 2>nul rem No need to use a loop, just call yourself call %0


Script to detect whether a process of the system exists. If it does not exist, automatically shut down.
http://www.cn-dos.net/forum/viewthread.php?tid=22861

tasklist >tasklist.txt rem Process name such as smss.exe find /i tasklist.txt "process name" if errorlevel 1 ((del /q tasklist.txt)&(goto end)) if errorlevel 0 ((del /q tasklist.txt)&(echo There is the process you want)&pause&exit) :end shutdown -s -t 1

But this only detects once when this bat runs, not real-time monitoring

Use Goto statement to do monitoring

:start tasklist >tasklist.txt find /i tasklist.txt "Explorer.exe" if errorlevel 1 ((del /q tasklist.txt)&(goto end)) if errorlevel 0 ((goto start)) :end shutdown -s -t 50

In this way, if the Explorer.exe process exists, it is an infinite loop.
Until the Explorer.exe process ends, the shutdown command is executed.
But this has a disadvantage of 100% CPU


Detect multiple specific processes
http://www.cn-dos.net/forum/viewthread.php?tid=27743
I want to implement such a function: list the current process list with tasklist, then use find to search whether the process contains 1.exe, 2.exe, 3.exe... (assuming). If one of them is in the list, perform a certain operation. I want to use FOR to implement the loop but can't get it to work. This is how I tried:
tasklist | for %%j in (1.exe,2.exe,3.exe) do find "%%j" && goto :p
Can't find use for? Please give pointers.
---------
tasklist | findstr "1.exe 2.exe 3.exe"&&goto :p
for will not accept the data passed from tasklist, it is defined by in
---------
@echo off set 1.exe=defined program set 2.exe=defined program set 3.exe=defined program for /f "tokens=1" %%i in ('tasklist /NH') do ( if defined %%i echo %%i ) pause>nul ---------


Detection and exit process problem
http://www.cn-dos.net/forum/viewthread.php?tid=25357
Processes A and B exist. If A does not exist, exit B. Detect every N seconds in a loop. After exiting B, exit the program

tasklist|findstr /i "A.exe" ||(taskkill /im B.exe /t /f&exit)

List the currently running processes, can customize the description content, manually close the process.
Can be improved to automatically judge and process the process.http://www.cn-dos.net/forum/viewthread.php?tid=27405

Learned something, thanks.

Good stuff, but, really don't want people with bad intentions to see this post

Newcomer reporting, come in and learn~

This thing is powerful, a bit scary

Learning

This thing is pretty good....
Get it down and learn it slowly...

Add a little something for the thread starter:
For starting explorer.exe, it is recommended to use "start explorer.exe"
Otherwise, the batch window cannot be automatically closed

This post is very practical, support the original poster.

Learning.

Can't understand it, it's like天书
