1.10.2 Package-specific documentation

Most of the important software packages in the UNIX and Linux world are maintained by individuals or by third parties such as the Internet Systems Consortium and the Apache Software Foundation. These groups write their own documentation. The quality runs the gamut from embarrassing to spectacular, but jewels such as Version Control with Subversion from svnbook.red-bean.com make the hunt worthwhile.

1.10.2 specialized documentation for software packages

Most of the important software packages in the UNIX and Linux world are maintained by individuals or third parties, such as the Internet Software Alliance (Internet Systems Consortium) and the Apache Software Foundation (Apache Software Foundation). These organizations typically document the packages they distribute. The quality of the document ranges from embarrassing to just looking, but because of treasures like svnbook.red-bean.com 's "Version Control with Subversion", it's worth taking the time to find.

UNIX vendors and Linux distributors always include the appropriate man pages in their packages. Unfortunately, they tend to skimp on other documentation, mostly because there really isn't a standard place to put it (check / usr/share/doc). It's often useful to check the original source of the software to see if additional materials are available.

UNIX vendors and Linux publishers always bring man man pages into their software. Unfortunately, they don't pay enough attention to other documents, mostly because there really isn't a standard place to save the document (see / usr/share/doc). It is often useful to check the origin of the software to see if there are more materials.

Supplemental documents include white papers (technical reports), design rationales, and book- or pamphlet-length treatments of particular topics. These supplemental materials are not limited to describing just one command, so they can adopt a tutorial or procedural approach. Many pieces of software have both a man page and an article. For example, the man page for vi tells you about the command-line arguments that vi understands, but you have to go to the in-depth treatment to learn how to actually edit a file.

Supplementary materials include white papers (technical reports), design specifications and books or pamphlets on topics. These supplementary materials are not limited to introducing a command, so they can be in the form of tutorials or disciplines. Many software have both man manuals and introductory articles. For example, vi's manual only tells users about the command-line arguments that vi can support, and users need to learn more about how to actually edit a file.

Books

The best resources for system administrators in the printed realm (aside from this book: -) are the O'Reilly series of books. The series began with UNIX in a Nutshell over 20 years ago and now includes a separate volume on just about every important UNIX and Linux subsystem and command. The series also includes books on the Internet, Windows, and other non-UNIX topics. All the books are reasonably priced, timely, and focused.

1.10.3 Books

Among the printed materials, the best source for system administrators is the O'Reilly series of books (except this one). Starting with UNIX in a Nutshell (UNIX Concise tutorials) 20 years ago, this series now has a separate book for each UNIX and Linux subsystem and command. This series of books also includes an introduction to topics other than Internet, Windows and other UNIX. All of these books are reasonably priced, timely and targeted.

Tim O'Reilly has become quite interested in the open source movement and runs a conference, OSCON, on this topic as well as conferences on other trendy techie topics. OSCON occurs twice yearly, once in the United States and once in Europe. See oreilly.com for more information.

RFCs and other Internet documents

The Request for Comments document series describes the protocols and procedures used on the Internet. Most of these documents are relatively detailed and technical, but some are written as overviews. They are absolutely authoritative, and many are quite useful for system administrators. See page 449 for a more complete description of these documents.

1.10.4 RFC and other Internet documents

RFC's series of documents describes the protocols and procedures used on Internet. Most of these documents are quite detailed and technical, but some RFC are written only as an overview. They are all absolutely authoritative, and many RFC are quite useful to system administrators. Refer to page 449 for a more complete description of these documents.

The Linux Documentation Project

Linux systems have another major source of reference information: the Linux Documentation Project at tldp.org. This site hosts a huge array of user-contributed documentation ranging from FAQs to full-length guides. The LDP also centralizes efforts to translate Linux-related documents into additional languages.

1.10.5 LDP

There is another major reference resource for the Linux system: the Linux filing project, located at tldp.org. The site holds a large number of user-contributed documents, ranging from FAQ to full-length guides. LDP also focuses on translating Linux-related documents into other languages.

Unfortunately, many of the LDP documents are not well maintained. Since Linuxyears are a lot like dog-years in their relation to real time, untended documents are apt to go out of date quickly. Always check the time stamp on a HOWTO or guide and weigh its credibility accordingly.

Unfortunately, many LDP documents are not well maintained right now. Because Linux's concept of time is much shorter than real time, unattended documents tend to become obsolete quickly. Be sure to check the timestamp on the HOWTO or guide and estimate its credibility accordingly.

1.11 OTHER SOURCES OF INFORMATION

The sources discussed in the previous section are generally the most reliable, but they're hardly the last word in UNIX and Linux documentation. Countless blogs, discussion forums, and news feeds are available on the Internet.

1.11 other information resources

The resources discussed in the previous sections are generally the most reliable, but they are rarely the only documents in the UNIX and Linux world. Internet is full of countless blogs, forums and new seeds.

It should go without saying, but Google is a system administrator's best friend. Unless you're looking up the details of a specific command or file format, Google should be the first resource you consult for any sysadmin question. Make it a habit; if nothing else, you'll avoid the delay and humiliation of having your questions in an on-line forum answered with a link to Google When stuck, Google.

But there is no doubt that Google is the best friend of system administrators. Unless you are looking up details of a particular command or file format, Google should be the preferred resource for consulting any system management issues. If not, get into the habit of checking Google so that you can avoid asking questions on online forums and being answered with a link to Google, resulting in time delay and loss of face. Ask Google if you don't make a decision.

We can't enumerate every useful collection of UNIX and Linux information on the Internet, but a few of the most significant ones are shown in Table 1.5.

Another fun and useful resource is Bruce Hamilton's "Rosetta Stone" page at bhami.com/rosetta.html. It contains pointers to the commands and tools used for various system administration tasks on many different operating systems.
