Fundamentals of Linux

By: Oliver Pelz

Overview of this book

Linux is a Unix-like operating system assembled under the model of free and open source software development and distribution. Fundamentals of Linux will help you learn all the essentials of the Linux command line required to get you started. The book will start by teaching you how to work with virtualization software and install CentOS 7 Linux as a VM. Then, you will get to grips with the workings of various command line operations, such as cursor movement, commands, options, and arguments. As you make your way through the chapters, the book will not only focus on the most essential Linux commands but also give an introduction to Bash shell scripting. Finally, you will explore advanced topics, such as networking and troubleshooting your system, and you will get familiar with the advanced file permissions: ACL, setuid, and setgid. Fundamentals of Linux includes real-world tasks, use cases, and problems that, as a system administrator, you might encounter in your day-to-day activities.

To get the most out of this book

You will need a basic lab setup and at least a system with 8 GB of RAM and a dual-core processor. If you are planning to create a virtual environment, then a system with the same memory and a quad-core processor is recommended.

A VirtualBox and a VMware workstation are the best options for Windows. For Mac systems, run the testing system on parallels.

Throughout the book, we have used CentOS 7 minimal as the operating system.
