Step-by-Step Guide to Identifying and Terminating Processes on Specific Ports

Introduction

This markdown provides a step-by-step guide to identify and terminate processes running on a specific port, catering to both Unix-based and Windows systems.

Handling Processes on a Port

Suppose you encounter an OSError: [Errno 98] Address already in use error while trying to run an application that requires port 8000. This commonly happens when another process is already using the same port.

Method 1: Using curl to Test the Port

One way to check if a process is using port 8000 is by attempting to access it:

curl 127.0.0.1:8000
