For those of you who need to get ready for your CompTIA Linux+ exam in a hurry, this book is exactly what you need. This book's got a bunch of practical tasks and focused revision to help you feel ready for your test. Every chapter is based around exam objectives and covers essential skills through step-by-step, scenario-based activities.

To start with, you will be working on recovering systems from GRUB prompts, fixing bootloader issues, and managing kernel modules. All the essential tasks, like handling file systems, logical volumes, RAID arrays and NFS mounts, are broken down into clear, easy-to-follow recipes. There'll be plenty of practice in user and group management, permissions, access control lists and troubleshooting login and authentication issues. It covers automation techniques with Bash and Python, helping you script daily operations and validate system states. There are some great practical activities that will take you through repairing repositories, managing packages and system updates, so you'll be all set to handle real-world Linux administration. Topics like networking, service management, firewall configuration and DNS troubleshooting are taught through hands-on exercises. The security section covers things like account hygiene, SELinux and AppArmor controls, and key audit tasks. It covers modern infrastructure skills too, with hands-on chapters on containers, virtualisation, Ansible, Git, and cloud-init for automated provisioning.

Every chapter ends with some practice questions that are based on the sort of stuff you might be asked in the CompTIA Linux+ exam, and the book finishes with two full mock exams to help you work out how ready you are.
