Andrew Roberts has done an exceptional job. His tutorials cover topics both for the absolute beginner and the medium experienced user. This is a must read! Actually, I found out about the above tutorials by this post, which contains an example of a book in LaTeX. Very interesting information.

The University of Georgia has set up a guide, small in size, but with content of high quality, which can help someone that knows the basics of programming to get started quickly. Of course, there are many other free online high quality guides, but this one can be perfectly used as a quick reference. Unfortunately, the author is not stated in that page, so I assume that it’s the result of some excellent team work.

Here are the contents:

  • General structure of awk scripts
  • Elementary awk programming
    • Elementary examples
  • Advanced awk programming
    • Advanced examples
  • Important things which will bite you

This is not his only tutorial though. His web site contains high quality information about awk, bash, regex, csh etc. I highly recommend it.

Most of these tutorials were written form 1989 – to 1995 for The Sun Observor. The tutorials may still refer to information as “last month” and next month.” The tutorials were planned to be put into a book, but Carpal Tunnel Syndrome make the book difficult to finish in the time frame the editor wanted.
These tutorials are Solaris-specific, and contained a lot of references to OpenWindows. Times have changed, but I hope the basic information will still be helpful.

Although these howtos have been written for Solaris, I, as a Linux user have benefited from them. I have referred back to them a gazillion of times. This is excellent work! Thanks, Bruce Barnett.

This is an excellent document that covers all aspects of the Red Hat Package Management system, not only providing general RPM usage information, but also includes in depth reference to RPM package creation and other advanced topics.

You should definitely read this one.

It can, besides many other things, substitute, append, remove characters or groups of characters or whole lines in a text file or the console output. You may find it difficult to use, but here is an excellent web page that will help you get going:

Bruce Barnett writes in his article:

Sed is the ultimate stream editor. If that sounds strange, picture a stream flowing through a pipe. Okay, you can’t see a stream if it’s inside a pipe. That’s what I get for attempting a flowing analogy. You want literature, read James Joyce.

Anyhow, sed is a marvelous utility. Unfortunately, most people never learn its real power. The language is very simple, but the documentation is terrible. The Solaris on-line manual pages for sed are five pages long, and two of those pages describe the 34 different errors you can get. A program that spends as much space documenting the errors than it does documenting the language has a serious learning curve.

Do not fret! It is not your fault you don’t understand sed. I will cover sed completely. But I will describe the features in the order that I learned them. I didn’t learn everything at once. You don’t need to either.

Read on…
