I want to implement such a function: Use tasklist to list the current process list, then use find to search whether the process contains 1.exe, 2.exe, 3.exe... (hypothetically). If the list contains one of them, perform a certain operation. I want to use FOR to implement the loop but it doesn't work no matter how I try! This is how I tried:
tasklist | for %%j in (1.exe,2.exe,3.exe) do find "%%j" && goto :p

Is find not usable with for? Please help from the experts.

tasklist | findstr "1.exe 2.exe 3.exe"&&goto :p

The for loop does not accept data passed from tasklist; it is defined with in

@echo off
set 1.exe=Program defined
set 2.exe=Program defined
set 3.exe=Program defined


for /f "tokens=1" %%i in ('tasklist /NH') do (
if defined %%i echo %%i
)
pause>nul

Wow, that's so fast!
Thanks to the person on the 2nd floor!
For the 3rd floor slore, what does /NH in 'tasklist /NH' mean in your example? Also, I don't quite understand 'if defined %%i echo %%i'.
And what does 'pause>nul' mean? I'm a noob, heh. Please be more specific, thanks.

I find that the atmosphere of this forum is really good. It's really not easy to find such a good place for learning! Please give more guidance to everyone, heh heh!

TASKLIST /NH
Specifies that column headers should not be displayed in the output.
Only valid for "TABLE" and "CSV" formats.

if defined ....
The DEFINED condition, if an environment variable is defined, it gets an environment variable

pause >nul
Masks the display result and does not display it on the screen

Can the code on floor 3 find the specified process? You must have made a mistake.

@echo off

set qq.exe=腾迅QQ&set explorer.exe=外壳&set iexplore.exe=浏览器&for /f %%i in ('tasklist /NH') do if defined %%i call echo %%%%i%%%%i

pause>nul

The code on floor 3 is completely fine.

@echo off

set qq.exe=腾讯QQ&set explorer.exe=外壳&set iexplore.exe=浏览器&for /f %%i in ('tasklist /NH') do if defined %%i call echo %%%%i%%%%i

pause>nul

I misunderstood! Sorry~~
I mistakenly thought that set 1.exe = the defined program where 1.exe is 1.exe. Actually, it should be the process to be killed. And "the defined program" is just written casually...
Hmm～Learn from the experts, thank you for the guidance from the above!

There is a problem here:

@echo off
set notepad.exe=notepad.exe
set mspaint.exe=mspaint.exe
set calc.exe=calc.exe
set num=0
setlocal EnableDelayedExpansion
for /f "tokens=1" %%i in ('tasklist /NH') do (
if defined %%i (
echo kill... %%i
taskkill /f /t /im %%i
set/A num=!num!+1
)
)
echo %num% processes were terminated.
pause>nul

If the statement taskkill /f /t /im %%i is written incorrectly. Will num still accumulate, how to handle it so that it does not accumulate?

Run the code I wrote to test, and you'll know that set qq.exe=腾讯QQ isn't just written casually.

In call echo %%%%i%%%%i:

For set, %%%%i%% shows the value when set, and %%i shows the name when set.

For for, %%i shows the value of the variable, and %%%%i%% shows the value of the variable named by the value of %%i.

When variable delay is enabled, call echo %%%%i%%%%i is written as echo !%%i!%%i, which is more obvious.

The running results are as follows:

Shell explorer.exe
Tencent QQQQ.exe
Browser iexplore.exe
Browser iexplore.exe
Browser iexplore.exe

If the taskkill /f /t /im %%i statement is wrong. The num will still accumulate. How to handle it so that it doesn't accumulate?

Any batch processing is calculated based on it being correct...
The wrong result is also different, not necessarily accumulating, and may not even run.
You can use if to detect the error %ERRORLEVEL%
