need help on picking a right book

hi,

I'm searching for a perfect book to learn awk programming, i started with sed&awk book, but i think this book might be outdated as it is written way back in 97 and also it doesn't have many examples. So, I thought of getting some advice from the experts here. Pls suggest me some books.

And , BTW im workign on KORN shell.

Thanks!

The sed & awk book by Doughtery and Robbins is the standard text.

awk and sed have been around for more than 20 years. They don't change all that much. If you are on linux there are some new flags for sed like -i. GNU coretutils always seems to provide a few extra bells and whistles.
