How to find exact match using PSLIST and FIND in Batch/CMD

Question

I am trying to find a running process and kill it using PSLIST and PSKILL however, I'm unable to get the errorlevel to set properly. Depending on the way I do it, it gets stuck on either 0 or 1. I originally had the code working the Taskkill and Tasklist commands, but the code has to run on Windows 2000 as well as XP.

I also have notepad++ running to edit the batch file. The following code doesn't differentiate between notepad++ or notepad.exe.

@echo off

reg.exe ADD "HKCU\Software\Sysinternals\PsKill" /v EulaAccepted /t REG_DWORD /d 1 /f >NUL
reg.exe ADD "HKCU\Software\Sysinternals\PsList" /v EulaAccepted /t REG_DWORD /d 1 /f >NUL

rem just to see output of pslist
PSLIST "notepad" 2>NUL
ECHO.
ECHO. 
PSLIST "notepad" 2>NUL | FIND /I /N "notepad"
echo The error level is %errorlevel%


IF %errorlevel% EQU 0 (
    ECHO Notepad is running and will be terminated.
    ECHO.
    PSKILL "notepad.exe" 2>NUL
)
IF %errorlevel% EQU 1 (
    ECHO Notepad was not running.
    ECHO Starting Notepad now...
    ECHO.
    start "" "notepad.exe"
)

Pause
EXIT

The above code gets stuck on 0. When I change the line with FIND command to FINDSTR as PSLIST "notepad" 2>NUL | FINDSTR /I /N "notepad.exe" then it gets stuck on 1.

Is there a way to get the PSLIST and FIND or FINDSTR command to return the correct errorlevel with an exact match?

Answer 1

How about using the -e parameter of pslist?

pslist -e notepad

It will set errorlevel to 0 when found, and 1 when not found. Also it is an exact match meaning it will not identify notepad++.

try this (displays only the interesting line):

PSLIST "notepad++" 2>NUL | FINDstr /I "notepad++"
echo %errorlevel%
PSLIST "notepad" 2>NUL | FINDstr /I "notepad[^+]"
echo %errorlevel%
