First Steps with Linux

Linux becomes easier to understand when its commands are taught as parts of a working system, not as a list to memorize. First Steps with Linux builds that wider view, starting with the terminal and filesystem before moving into the everyday tasks of managing users, software, storage, processes, and networks.

Across six parts and sixteen chapters, the book develops from introductory concepts into practical command-line administration. Its coverage spans common Linux families, including Ubuntu and Fedora, so readers can see how core ideas carry across different environments.

Start with the Linux foundations

The opening chapters introduce Linux, distributions, system architecture, and the role of the command line. They also explain ways to get started using virtual machines, WSL, Vagrant, live media, or a browser-based environment. From there, readers practice navigating directories, handling files, using links, and finding help through command documentation and man pages.

Build confidence with access and administration

Permissions, ownership, users, and groups form a substantial part of the book. Alongside familiar tools such as chmod, chown, and sudo, it introduces advanced access controls, including ACLs and filesystem attributes. Software-management chapters compare tools such as apt, dpkg, dnf, and RPM, while storage chapters progress through filesystems and mounts to swap, LVM, RAID, NFS, autofs, and quotas.

Make the command line work harder

Text-processing chapters explore editors, searching, filtering, redirection, and regular expressions. The book also covers creating and handling archives with tar, working with compression formats, and using tools such as gzip and zip. These topics help connect individual commands into useful ways of working with files and system information.

Processes, scheduling, and networking

Later chapters examine processes, services, resource use, and open files, then turn to automating tasks with cron, at, batch, and systemd timers. The networking section covers interfaces, IP addresses, connectivity checks, SSH, file transfer, and Linux routing concepts including routing tables, metrics, and policy-based routing.

A structured route into practical Linux

The chapter-by-chapter progression makes this a useful starting point for readers new to Linux and a broad refresher for anyone strengthening command-line and administration skills. Rather than treating Linux as a collection of unrelated commands, it shows how foundational tools and system tasks fit together.
