Book Description

For people who create and modify text files, sed and awk are power tools for editing. Most of the things that you can do with these programs can be done interactively with a text editor. However, using sed and awk can save many hours of repetitive work in achieving the same result.

To master sed and awk you must thoroughly understand UNIX regular expressions, and understand the syntax of sed and awk commands. This handbook treats regular expressions as a foundation for learning about sed and awk and contains a comprehensive treatment of sed and awk syntax. It emphasizes the kinds of practical problems that sed and awk can help users to solve, with many useful example scripts and programs.

Contents include:

  • A tutorial showing basic operations of sed and awk
  • Regular expression syntax and examples
  • Basic and advanced sed commands
  • Features of awk (plus gawk and nawk)
  • Common programming constructs
  • Advanced topics
  • User-contributed scripts

5.0 out of 5 stars Easy. Organized. To the point. 19 Oct 1999
By A Customer - Published on Amazon.com
Format:Paperback
I grabbed this old edition from my co-worker and found it very well written. I am sure the new (2nd) edition is even better and up to date.

3.0 out of 5 stars Somewhat useful 24 Feb 2013
By William Maloney - Published on Amazon.com
Format:Paperback|Verified Purchase
I bought a used copy, which turned out to have been printed in 1992. Operating system references are to UNIX, as Linux was a virtually-unknown infant at the time; references to various software utilities is similarly dated. The 2nd edition might be somewhat better; it's listed as a 1997 edition, so it may actually be aware of Linux. Even so, I would be skeptical of spending the dough on a pig in a poke.

Dated material aside, I found the book difficult to use, even though I've been learning programming languages since 1982 -- including that early, primitive BASIC, 8086 assembly, Pascal, C, C++, Perl, HTML, Java, VB, and others. The flow of its materials presentation doesn't seem to build naturally from ground zero. Perhaps if I'd learned programming on a UNIX machine, the references in this book would be clearer.

So, heads up if you're looking to learn sed and awk. This book can probably be of some help (especially if you're a UNIX geek), but you may well need to augment it with a lot of on-line or other research.
5.0 out of 5 stars Great book and sed and awk. 14 Jan 2014

This book explains sed and awk well and gives useful code examples to help understand how to write sed and awk scripts.
5.0 out of 5 stars This book has saved my bacon 27 Jan 2013
By bernie - Published on Amazon.com
Format:Paperback
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.

3.0 out of 5 stars Great book but did I really need the previous owners stick notes? 30 Nov 2013
By dark rain - Published on Amazon.com
Format:Paperback|Verified Purchase
exactly what I needed (despite the age) but I wonder if the seller actually looks at their products.
Besides a few pencil marks there was several postit notes in the books with scribbles of this and that.
You would think that these would av been removed.
