How to Kill a Specific Port (8080)on Windows, Linux, and macOS

  Sometimes, you might encounter a situation where a program or process is using a specific port that you need to use for another application. In such cases, you can kill the process that's using the port to free it up. In this blog post, we'll see how to kill a specific port on Windows, Linux, and macOS.

Windows:

  1. Open the Command Prompt as an administrator.
  2. Type the following command to find the process that's using the port: netstat -ano | findstr :<port number> Replace <port number> with the actual port number you want to kill.
  3. Note down the PID (Process ID) of the process.
  4. Type the following command to kill the process: taskkill /PID <PID> /F Replace <PID> with the actual process ID you noted down in the previous step.

Linux:

  1. Open the Terminal.
  2. Type the following command to find the process that's using the port: sudo lsof -i:<port number> Replace <port number> with the actual port number you want to kill.
  3. Note down the PID (Process ID) of the process.
  4. Type the following command to kill the process: sudo kill <PID> Replace <PID> with the actual process ID you noted down in the previous step.

macOS:

  1. Open the Terminal.
  2. Type the following command to find the process that's using the port: sudo lsof -i :<port number> Replace <port number> with the actual port number you want to kill.
  3. Note down the PID (Process ID) of the process.
  4. Type the following command to kill the process: sudo kill <PID> Replace <PID> with the actual process ID you noted down in the previous step.

Conclusion: Killing a specific port on Windows, Linux, and macOS is easy once you know the process ID of the program that's using the port. Use the above commands to free up the port for other applications.

Windows 


netstat -ano | findstr :<port number>
taskkill /PID <PID> /F
Linux 

sudo lsof -i:<port number>
sudo kill <PID>
macOS 


sudo lsof -i :<port number>
sudo kill <PID>
