How to query netstat to find PID for specific local address in Windows 7?

Question

I frequently start server on local address [::]:8080. To terminate server I need PID fetched from netstat -aon.

To terminate this server I do taskkill /F /PID <found pid>

I want to create windows batch file that can find PID and apply it in call taskkill /F /PID <found pid>

How can I create such batch file?

Thanks!

Answer 1

On my PC there could be a UDP or TCP connection and they require slightly different code:
Test this to see if one of the taskkill commands looks right and remove echo to enable the taskkill command.

@echo off
for /f "tokens=5" %%a in ('netstat -aon ^|find " [::]:8080 " ^|find /i " TCP " ') do echo taskkill /F /PID %%a

for /f "tokens=4" %%a in ('netstat -aon ^|find " [::]:8080 " ^|find /i " UDP " ') do echo taskkill /F /PID %%a

Answer 2

@echo off

    setlocal enableextensions

    set "port=8080"

    for /f "tokens=1,4,5" %%a in (
        'netstat -aon ^| findstr /r /c:"[TU][CD]P[^[]*\[::\]:%port%"'
    ) do if "%%a"=="UDP" (taskkill /F /PID %%b) else (taskkill /f /PID %%c)

    endlocal

Use findstr to retrieve only the needed record, tokenize it using the for command to get the PID column (4th for UDP, 5th for TCP) and kill the task
