Free eBook “GNU/Linux Basic” from Free Technology Academy. The aim of this book is to initiate you into the world of GNU/Linux. It covers the basics of the free software, how to use and modify GNU/Linux to suit your needs, and how to find your way in this new world more easily.
Nonetheless, this document is not an essential reference guide for administrators and/or users; there are already hundreds of manuals, how-to guides and other reference works numbering thousands of pages that serve this purpose. Our aim here is to help you take your first steps in this as-yet uncharted territory for too many users and administrators, and to explain how to tackle and resolve potential problems by yourself.
