This article shares with you about how batch processing implements process port viewing. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Just save the following code as port_bat.bat and run it.

The code is as follows:

@ echo off

Color a

Title XP Port-process query

Setlocal enabledelayedexpansion

Echo ╔-- ╗

The port opened locally by echo and the processes that use it

Echo ╚-- ╝

Echo--

Echo port number process name

ECHO TCP protocol:

Use the netstat command to find out the port that uses the TCP protocol to communicate, and divide the result

:: pass the second parameter (IP plus port) to% I and the fifth parameter (PID number) to% j

For / F "usebackq skip=4 tokens=2,5"% I in (`"netstat-ano-p TCP"`) do (

Call: Assoc% I TCP% j

Echo! TCP_Port!! TCP_Proc_Name!

)

ECHO UDP protocol:

For / F "usebackq skip=4 tokens=2,4"% I in (`"netstat-ano-p UDP"`) do (

Call: Assoc% I UDP% j

Echo! UDP_Port!! UDP_Proc_Name!

)

Echo press any key to exit

Pause > nul

: Assoc

:: split% 1 (the first parameter) and pass the second parameter to% e. In this program,% 1 is the% I above (in the form: IP: Port number)

For / F "tokens=2 delims=:" e in ("1") do (

Set 2_Port=%%e

)

:: query the process whose PID is equal to% 3 (the third parameter) and pass the result to the variable? _ Proc_Name,? Stands for UDP or TCP

For / F "skip=2 usebackq delims=, tokens=1" an in (`"Tasklist / FI" PID eq 3 "/ FO CSV"`) do (

::% ~ a means to remove the quotation marks outside% a, because the result of the above command is enclosed in parentheses.

Set 2_Proc_Name=%%~a

)
