The huge, enthusiastic Ubuntu community has swept up thousands and thousands of new Ubuntu Linux users. If you are one of them, you will probably soon find yourself wanting to dig beneath the surface of Ubuntu’s applications and graphical tools. You’ll want to become a power user. Becoming a power user with any Linux system means being able to work from the command line. Few graphical interfaces will provide you with the options and flexibility you get with commands that address the same features. Ubuntu Linux Toolbox provides you with more than 1000 specific command lines to help you dig deeply into Linux. Whether you are a systems administrator or desktop user, the book will show you commands to create file systems, troubleshoot networks, lock down security, and dig out almost anything you care to know about your Linux system. This book’s focus for your Linux command-line journey is Ubuntu, the communitybased Linux distribution sponsored by Canonical Ltd., and the Debian GNU/Linux system on which it is based. Tapping into the skills needed to run those systems can help you to work with your own Linux systems and to learn what you need as a Linux professional.

Since its inaugural release in 2004, Ubuntu (www.ubuntu.com) has become the most popular and, arguably, best loved of the Linux distributions. From its name, which translates to humanity toward others, to its focus on support for many languages and special needs, Ubuntu has reflected its ideals of spreading free software beyond the standard Linux target markets of geeks and corporate servers. The Ubuntu project does everything it can to help ease new users into using its Linuxbased Ubuntu operating system. Ubuntu live CDs let a new user try out Ubuntu before installing it. If the user likes Ubuntu, a single click can start an Ubuntu install to hard disk. And because Ubuntu is based on Debian GNU/Linux, Ubuntu has been able to make massive amounts of software from the Debian software repositories available free to Ubuntu users.
