The Most Complete, Easy-to-Understand, and Useful Guide to Ubuntu Linux Desktops and Servers

Ubuntu Linux is a state-of-the-art operating system, and you need a book that’s just as advanced.

Best-selling author Mark Sobell begins by walking you through every feature and technique you need to know, from installing Ubuntu–using the DVD included with the book–to working with GNOME, Samba, exim4, Apache, DNS, NIS, firestarter, and iptables. Sobell’s exceptionally clear explanations demystify everything from system security to Windows file/printer sharing.

Sobell presents full chapters on using Ubuntu from the command line and GUI; thorough system administration and security guidance; and up-to-the-minute, step-by-step instructions for setting up networks and every major type of Internet server. Along the way, you’ll learn both the “hows” and the “whys” of Ubuntu. Sobell knows every Linux nook and cranny: He’s taught hundreds of thousands of readers and never forgets what it’s like to be new to Linux. Whether you’re a user, administrator, or programmer, this book gives you all you need–and more.

Learning the bash Shell

The first thing users of the Linux operating system come face to face with is the shell. "Shell" is the UNIX term for a user interface to the system — something that lets you communicate with the computer via the keyboard and display. Bash, the Free Software Foundation's "Bourne Again Shell," is the default shell for Linux, the popular free UNIX-like operating system. It's also a replacement for the standard UNIX Bourne shell, which serves both as a user interface and as a programming language. Like the FSF's other tools, bash is more than a mere replacement: it extends the Bourne shell in many ways. Features include command line editing, key bindings, integrated programming features, command completion, control structures (especially the select construct, which enables you to create menus easily), and new ways to customize your environment.

Whether you want to use bash for its user interface or its programming features you will find Learning the bash Shell a valuable guide. The book covers all of bash's features, both for interactive use and programming. If you are new to shell programming, Learning the bash Shell provides an excellent introduction, covering everything from the most basic to the most advanced features, like signal handling and command line processing. If you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. The book is full of examples of shell commands and programs that are designed to be useful in your everyday life as a user, not just to illustrate the feature being explained. All of these examples are freely available to you online on the Internet.
