What part are you actually struggling with - and why a batch file? — BugFinder, Oct 30 '17 at 08:46
send a message to that specific port and see if it can receive — Rahul, Oct 30 '17 at 08:47
Needed a batch file as i'm using it in an alert system, so that i will be notified if port is not listening — Tanuja kurkute, Oct 31 '17 at 12:29

Thanks i did with findstr netstat -o -n -a | findstr 8086 if %ERRORLEVEL% equ 0 goto FOUND echo port not found goto FIN :FOUND echo port found :FIN Note: When an item is not found FINDSTR will return an %ERRORLEVEL% > 0 if item is found FINDSTR will return an %ERRORLEVEL% = 0 – Tanuja kurkute Oct 31 '17 at 12:32

Also as a one-liner which is useful sometimes netstat -nao | findstr "LISTENING" | findstr "0:8086" >nul 2>nul && (echo Port 8086 is open) || (echo Port 8086 is closed && exit 1) Note the "exit 1" which returns an %ERRORLEVEL% > 0 – posix99 Jun 27 '18 at 13:12

netstat -o -n -a | findstr 8086

if %ERRORLEVEL% equ 0 goto FOUND

echo port not found

goto FIN

:FOUND

echo port found

:FIN

Note: When an item is not found FINDSTR will return an %ERRORLEVEL% > 0 if item is found FINDSTR will return an %ERRORLEVEL% = 0
