This book is a comprehensive introduction to the use and programming of the UNIX operating system. It focuses on the complete range of UNIX topics including shells and files, networks and the Internet, filters, programming, standard editors and system administration. The text introduces UNIX in three phases. The first section is a tutorial orientation to the UNIX environment. The examples are meant to be simple and assume no prior knowledge. In the second part, readers move into essential uses of UNIX to accomplish everyday tasks. Finally, the book wraps up with advanced topics and overviews of specific applications, giving readers a core level of understanding to successfully work in the UNIX environment. * Task-oriented presentation of UNIX commands and a Command Reference section * Detailed presentation of how to use UNIX filters, regular expressions and AWK programs * Coverage of shell configuration, scripts and features for the major UNIX shells * Documentation of UNIX communications tools, including e-mail, news, Internet tools and remote access operations

C differs from most programming languages in its use of pointers, functions, and files. For those learning C, pointers are the greatest source of confusion. The primary aim of this book is to provide working models of how pointers are used in C. Pointers are used differently with every programming feature and Introductory C, Second Edition, emphasizes how each new programming feature relates to the use of pointers to provide a thorough understanding of the applications throughout C. Introductory C, Second Edition, offers a detailed explanation of Arrays in C over several chapters, describing strings, arrays of structures, multi-dimensional arrays, and arrays of pointers. The underlying implementation of arrays using pointersis described in detail with such features as pointers to elements, pointers to arrays, and pointers to pointers. File access methods using text and binary files are also given thorough coverage: character, line, formatted text files, and record binary files are described, and the implementation of file access functions is described in detail. This book will be of great use to programmers at all levels. Key Features * Includes three new chapters introducing C++, including coverage of classes, objects, constructors, overloading, inheritance, and derivation * Contains a floppy disk with source code from examples in the book

Unix has becomes the foremost operating systems platform for network servers and workstations. Many of the tools used currently for Internet access were designed originally on Unix. Unix Networking Clearly Explained focuses on the Unix tools used for network and Internet access. The book covers the essentials of electronic mail as well as popular Unix mailers such as mailx, elm, pine, and mh. Detailed configuration features are addressed for each mailer. The various Unix newsreaders are covered in depth including trn, tin, and nn. The book also covers Internet tools as archie, telnet, ftp, Web browsers, and Gopher. While not intended as a unix primer for system administration Unix Networking Clearly Explained will introduce the basics of network administration. The focus of this book is on the end-user client software, rather than the technicalities of network administration. The aim of the book is to help users make use of all the Unix tools available on their local networks and the Internet. The content will introduce the reader to the complete range of unix networking capabilities so that a computing professional new to Unix will understand the basics before moving into the more complex area of Unix system administration.

This book examines Red Hat Enterprise Linux 7 for the desktop user and administrator (covers RHEL 7.4). Though administrative tools are covered, the emphasis is on what a user would need to know to perform tasks. The focus here is on what users face when using Red Hat Enterprise Linux 7, covering topics like applications, the GNOME and KDE desktops, shell commands, and the administration and network tools. Desktops are examined in detail, including configuration options. Administration topics are also covered including user management, software management, repositories, services, systemd, system monitoring, shell configuration, encryption, network connections, shared resources, authentication, SELinux, firewalls, shell configuration, backups, and printers.

The "Ubuntu 16.04 LTS Desktop: Applications and Administration" covers the Ubuntu 16.04 LTS (Xenial Xerus) release, focusing on applications and administrative tools. The emphasis here is on what users will face when using Ubuntu, covering topics like installation, applications, software management, desktops, shell commands, network connections, and system administration tasks. The Ubuntu Desktop (Unity), Kubuntu, Ubuntu Mate, and Ubuntu GNOME desktops are examined in detail. 16.04 introduces several new features, as well as numerous smaller modifications. It is a long-term support release. The Ubuntu desktop with the Unity interface is examined in detail. Unity uses a launcher and a dash to manage access to applications and devices.
