5.0 out of 5 stars 2 cute little guys that will work hard for you
I've had this book for 3-4 years now and find it to be mu handiest refernce. I even use ot more than my vi book.
The raw power of sed and awk will humble even the proudest VB programmer and this book will help you get the most out of both the "Aho, Weinberg and Kernigan" and the "stream editor".
The first chapter section is entitled "May...

3.0 out of 5 stars The best (only?) book to learn these tools from A to Z
I had to do some text processing and I wanted to learn sed & awk so I picked this book that is, to my knowledge, the only book completely dedicated to these tools. The chapter on 'advanced' sed programming is very scary because when using 'advanced' sed features, the syntax is cryptic. It is nice to know that these features are there but I want to stay away from them and...

5.0 out of 5 stars This book has saved my bacon, May 30 2000

This review is from: sed & awk (Paperback)
Say what you will about the depth of this book. I am here to tell you that on more than one occasion this book has saved my bacon. Several times in different environments I needed to use sed to correct data in flat files. Once I used sed to change the format and numbers when we wanted to match accounting numbers to a different system. I haven't used that much awk. However there has been occasion to transfer awk programs from one Unix to a different Unix flavor. I found that the regular awk in this book was newer than the newawk in the other system. I Still keep the book handy incase I get squeezed for time and have to manipulate files. However I am learning more and more to appreciate PERL on those occasions.

4.0 out of 5 stars Great introduction, mediocre reference, May 12 2000

This review is from: sed & awk (Paperback)
I was very interested in learning sed and awk, and so picked up this book. Like most O'Reilly titles, it is an excellent piece of work. I learned a great deal and was able to get started and pump out some useful code after spending some time with this book. However, I soon found that when it came to tackling some very difficult tasks with sed and awk, this book didn't seem to serve me very well as a reference. I have a feeling that sed and awk are not the sort of thing that one could learn with just one book; there are so many applications for these tools that one must choose what one wishes to do, and find the right books to supplement this excellent text.

4.0 out of 5 stars Powerful tools for text manipulation, April 15 2000
This review is from: sed & awk (Paperback)
Unix has earned itself quite a reputation for its potent tools, used for batch editing of text files (like program output). Sed and Awk are two of these tools. Sed is a direct descendent of Ed, the original Unix line editor, which employs regular expressions, a powerful method for description of patterns in text, for operations like substitute, append or delete. Awk is a complete scripting language with programming structures like conditionals, loops, functions etc., developed in 1970's by Alfred Aho, Brian Kernighan and Peter Weinberger (hence A-W-K). The trio has also written a book on Awk.

Dale Dougherty (in the 2nd edition with Arnold Robbins, maintainer of GNU Awk and author of several more books on Awk programming language) have made a good job in making a thoroughly readable tutorial on Sed and Awk. However, it remains a mystery to me how they succeeded to fill no less than 407 pages with it. Mind you, Sed and Awk are not really some big monsters. There exist something like two dozens of operators in Sed (most of them you will probably never use), and the syntax of Awk mimics those of C programming language, so it is likely that you know it already. Once you grok the idea of regular expressions, you should become a proficient user of Awk in about 30 minutes.

In conclusion, go buy the book if your need to manipulate text files on Unix and you think you need a lengthy tutorial with a gentle learning curve. Otherwise, short references on Awk and Sed, like the ones in "Unix Power Tools" and a bunch of examples showing some tricks you might not think of, will probably be more useful. In addition, it is good to know that during the nineties, much of the focus has drifted from Awk to Perl, so you might consider a book on Perl as well.

5.0 out of 5 stars A Must !, Jan. 13 2000
This review is from: sed & awk (Paperback)
This book from the GREAT O'reilly Collection is a must for anyone who wants to master 'sed' and 'awk', a POWERFUL set of Unix tools, which are too often ignored or under-utilized. Written in plain english, this book will satisfy the advanced and the novice users. Greatly recommended !

3.0 out of 5 stars Good tutorial, problematic reference, May 25 1999
This review is from: sed & awk (Paperback)
I suppose if the proof of the teaching is in the learning, the authors' idea (in this edition) of interlacing their discussions of Sed and Awk throughout the volume is vindicated, because I am learning easily from the book. Yet this organization detracts seriously from its reference value, especially when one uses the index.
You can look up a feature which you need to review, turn to one of the listed pages, begin reading, and then realize that you have no idea which program is being described. While the approach is an interesting experiment, I question whether its benefits are worth such drawbacks. If the authors decide to continue the approach in later edition, a simple device such as different type faces of page references in the index (e.g. Roman for Awk, the more elaborate package, and Italic for Sed) would help relieve this problem.

4.0 out of 5 stars A must have for the wannabe UNIX wizard, April 23 1999
By A Customer
This review is from: sed & awk (Paperback)
This is a good book. Although I find some of the information that I need. There seems to be a fair amount that's concealed by the books approach to each topic.

5.0 out of 5 stars A necessity for every Unix System Administrator, Nov. 10 1998
By A Customer
This review is from: sed & awk (Paperback)
This is a well written technical book. It will lead you from the very basic to the most advance concept of sed & awk. It will first build a good foundation by explaining the basics of reg. exps. then gradually teach you how to apply it using the editors.

4.0 out of 5 stars Great book for beginners., Sept. 17 1998
By A Customer
This review is from: sed & awk (Paperback)
Just finished it. Great book for beginners, tends to focus a bit on the non-programmer. However, it is revealing, showing you how to automatically edit things you usually do manually. Could have used some exercises, and some special problems at the end of each chapter, so you could practice what you learned in that chapter. Great book otherwise.
