O'Reilly publishers offer several excellent books on Linux systems. Many of their books can also be read online. For more information check out the following links:
-
O'Reilly Publisher of the iconic "animal books" for software developers, O'Reilly is the information source of choice for technologists, now also delivering the knowledge of expert early adopters to everyday computer users.

The Free Software Foundation (GNU) has a large selection of documentation. Here we point out the gcc, gdb, and make manuals see http://www.fsf.org/. There are more recent on-line versions available at, which can normally be found on the project pages.
There are many other publishers/authors who have some excellent books on Linux and embedded Linux. Here are a few which we have found useful, and a good addition to anyone's desk reference.
-
Bruce Perens also has quite a good series on Linux topics
-
Linkers and Loader is good for people interested in low level ELF/ldso details. It's available for free, or you can buy it via Amazon
The Linux Documentation Project (LDP) create and distribute the canonical set of free GNU/Linux documentation. While GNU/Linux applications and utilities may come with their own documentation, LDP documentation fills in the numerous gaps.
The hundreds of existing LDP documents present both overviews and details of: the GNU/Linux Operating System, System Administration, Hardware, Networks, Servers, GUIs, Programming, Language Support, etc. Not every important topic is currently covered so LDP is always seeking new authors to fill in the gaps.
The LDP publishes various types of documentation:
- HOWTOs - subject-specific help
- Guides - longer, in-depth books
- FAQs - Frequently Asked Questions
- man pages - help on individual commands
- Linux Gazette - online magazine
Another important source of information is the man (for manual) page system which is an online documentation system that comes with the typical Linux distribution. For example, let's say you want to find out about shell scripting with the bash shell. Then you merely enter at the command line: man bash and you'll get a a document about bash displayed on the console. The typical Linux distribution also comes with documentation in other directories such as:
$ /usr/doc
$ /usr/src/linux/Documentation
$ /usr/X11R6/lib/X11/doc
An embedded Linux system must save space so some or all of this documentation may be unavailable on the embedded system itself, but some may be available elsewhere e.g. On a CD that came with the embedded version.
There are also paper-based and web-based journals. Here we mention two that come in both media and are very good:
- http://www.linuxdevices.com/ - Information on various embedded devices which run Linux
- http://www.weird-solutions.com/ - Free DHCP and TFTP server programs for Windows
- adi>blackfin - information on Analog Devices' Blackfin processor device family
- http://www.linuxquestions.org/ - a friendly and active Linux Community, which can help you out with your basic questions
- http://kernelnewbies.org/ - answers to your basic questions
- http://www.linuxforums.org/forum/ - Linux forums - another places to try for basic help and understanding
- http://www.linuxhelp.net/ - Linux help - yet another place to try
