Practical Linux with Raspberry Pi OS : Quick Start

Quickly start programming with Linux while learning the Raspberry Pi OS―the Linux distribution designed specifically for low-cost Raspberry Pis. This short guide reviews Linux commands, GUI, and shell scripting in a holistic manner by diving into both advanced and day-to-day tasks using the Raspberry Pi OS.You'll comfortably work with the Linux command prompt, and explore the RPi OS GUI and all its base applications. Then move into writing your own programs with shell-programming and using high-level languages such as C, C++, and Python 3. You’ll also study hardware and GPIO programming. Use Python 3 for GPIO programming to drive LEDs and pushbuttons.Examples are written in Shell, C, C++, and Python 3. Graphical output is displayed in helpful screenshots that capture just what you’ll see when working in this environment. All code examples are well tested on actual Raspberry Pi boards. After reading this book and following the examples, you’ll be able to write programs for demonstration in your academic/industrial research work, business environment, or just your circle of friends for fun! **What You'll Learn** * Navigate the core aspects of Linux and programming on a Linux platform * Install Raspberry Pi OS on a Raspberry Pi * Program in Shell, C, C++, and Python * Redirect Io and work with the crontab **Who This Book Is For** Linux enthusiasts, software engineers, researchers, business analysts, and managers working with the low-cost Raspberry Pi.
