On Windows, how can I find which process is listening on a given port and kill it? For example, I want to find and kill the process listening on
We can do this using the Windows command line. Run
cmd.exe as an administrator and enter the following command:
netstat -ano | findstr :8080
In the first part of this command, we invoke
netstat, a utility for viewing network connections.
-ashows all connections and listening ports.
-nshows IP addresses and port numbers numerically.
-oshows the process ID for each connection or listening port.
This will show all current TCP connections on our system. In the second part of the command, we pipe this output into
findstr to find and display the line showing information about the process listening on TCP port 8080. Our output should resemble the following:
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 2660 TCP [::]:8080 [::]:0 LISTENING 2660
The final number on both lines is the process ID (PID) of the process using port 8080. Using this PID, we can end the process with
taskkill /PID 2660 /F
/PID flag indicates that we’re locating the task to kill by PID, and the
/F flag will forcefully end the task. After running this command, we should see the following output:
SUCCESS: The process with PID 2660 has been terminated.
If we rerun the
netstat command above, we should now get empty output.
A quicker way to do this, with only a single command, is to use the NPM package
kill-port. With NPM installed, just run the following command:
npx kill-port 8080
