Effortlessly Execute a Shell Script in Linux from a Java Program

Running shell scripts directly from a Java application can streamline your workflow and expand your application's capabilities. Whether you're automating routine tasks or integrating complex operations, this guide will show you how to execute a shell script in Linux from your Java program.

Prerequisites

Before diving into the implementation, ensure you have the following:

Java Development Kit (JDK) installed on your system.

Basic knowledge of bash scripting in Linux.

Shell script you want to execute.

Understanding the Basic Concept

Java provides the ProcessBuilder class, which allows you to start and manage separate processes. By leveraging ProcessBuilder, you can invoke a shell script from within your Java application.

Step-by-Step Implementation

Here's a simple way to execute a shell script from a Java program.

Step 1: Create Your Shell Script
