Our goal is to cover the basics of Ubuntu (su as installation and working with the desktop) as well as guide you through some of the most popular applications. We designed this guide to be simple to follow with step-by-step instructions and plenty of screenshots, allowing you to discover the potential of your new Ubuntu system even if you are a novice computer user or are migrating from another operating system for the first time. Please bear in mind that this guide is still very mu a work in progress and always will be. It is wrien specifically for Ubuntu . , and al- though we have aimed to not limit our instructions to this version it is un- avoidable that some things will ange over the life of Ubuntu. Whenever a new version of Ubuntu is released, we will incorporate any anges into our guide, and make a new version available at http://www.ubuntu-manual.org. Geing Started with Ubuntu . is not intended to be a comprehensive Ubuntu instruction manual. It is more like a qui-start guide that will get you doing the things you need to do with your computer quily and easily, without geing bogged down in tenical details. If you are aer more detail, there are excellent resources available at http:// help.ubuntu.com. Ubuntu’s built-in system documentation is also very useful for accessing help on specific topics, and can be found by cliing System ‣ Help and Support in Ubuntu. If something isn’t covered here, ances are More information about Ubuntu’s online you will find the information you are looking for in one of those locations. and system documentation can be found in Chapter : Learning More. We will try our best to include links to more detailed help wherever we can. Ubuntu philosophy e term “Ubuntu” is a traditional African concept that originated from the Bantu languages of southern Africa. It can be described as a way of connect- ing with others—living in a global community where your actions affect all of humanity. Ubuntu is more than just an operating system: it is a community of people that come together voluntarily to collaborate on an international soware project that aims to deliver the best possible user experience. The Ubuntu promise ‣ Ubuntu will always be free of arge, along with its regular enterprise releases and security updates. . ‣ Ubuntu comes with full commercial support from Canonical and hundreds of companies from across the world. ‣ Ubuntu provides the best translations and accessibility features that the free soware community has to offer. ‣ Ubuntu core applications are all free and open source. We want you to use free and open source soware, improve it, and pass it on. A brief history of Ubuntu Ubuntu was conceived in by Mark Shuleworth, a successful South African entrepreneur, and his company Canonical. Shuleworth recognized Canonical is the company that provides the power of Linux and Open Source, but was also aware of weaknesses that financial and technical support for Ubuntu. They have employees based around the prevented mainstream use. world who work on developing and im- Shuleworth set out with clear intentions to address these weaknesses proving the operating system, as well as reviewing work submied by volunteer con- and create a system that was easy to use, completely free (see Chapter : tributors.

With the Debian system as a base, Shuleworth began to build Ubuntu. Using his own funds at first, installation s were pressed and shipped worldwide at no cost to the end user. Ubuntu spread quily, the size of the community rapidly increased, and it soon became the most popular Debian-based Linux distribution available. Now with more people working on the project than ever before, Ubuntu continues to see improvement to its core features and hardware support, and has gained the aention of large organizations worldwide. For example, in Dell began a collaboration with Canonical to sell computers with Ubuntu pre-installed. Additionally, in the Fren Police began to transition their entire computer infrastructure to a variant of Ubuntu—a process whi has reportedly saved them “millions of Euro” in licensing fees for Microso Windows. By the year , the Fren Police anticipates that all of their computers will be running Ubuntu. Canonical profits from this arrangement by providing tenical support and custom-built soware. While large organizations oen find it useful to pay for support services, For information on Ubuntu Server Edition, Shuleworth has promised that the Ubuntu desktop system will always be and how you can use it in your company, visit http://www.ubuntu.com/products/ free.

Ubuntu is built on the foundation of Linux, whi is a member of the Unix family. Unix is one of the oldest types of operating systems and has provided reliability and security in professional applications for almost half a century. Many servers around the world that store data for popular websites (su as YouTube and Google) run some variant of a Unix system. Linux was designed from the ground up with security and hardware com- Whilst modern graphical desktop envi- patibility in mind, and is currently one of the most popular Unix-based op- ronments have generally replaced early command line–based operating systems, erating system.

You will no doubt notice many similarities to both Microso Windows and Mac , as well as some things that work very differently. Users coming from Mac are more likely to notice similarities due to the fact that both Mac and Ubuntu originated from Unix.
