However, if you're running a Python script that takes a long time to complete (like over 48 hours!), you may find yourself in a situation where you can't keep your computer or SSH connection active throughout the execution time. The Problem You may have a Python script that processes a large dataset, conducts a lengthy computation, or performs an automation task. The issue arises when you try to run this script on your Virtual Private Server (VPS). Logging out or losing your SSH connection can interrupt the script, leading to incomplete tasks and wasted time. The Solution: Using nohup Fortunately, there is a simple and effective way to run your Python script in the background on your VPS using the nohup command. The nohup (no hang up) command allows your processes to continue running even after you have logged out of your SSH session. Here’s how you can do it: Step-by-Step Instructions Access Your VPS: First, log in to your VPS using SSH. You can use a command like this in your terminal: [[See Video to Reveal this Text or Code Snippet]] Make sure to replace user and your_vps_ip with your actual username and VPS IP address.
