4.0 out of 5 stars A fairly painless, helpful introduction to UNIX scripting, May 24, 2003

This review is from: Unix Shell Programming (3rd Edition) (Paperback)

"UNIX Shell Programming, 3rd Ed" (USP3E) is probably the book to buy if you're a beginning UNIX user with dreams of writing shell scripts. The book does a good job of explaining many of the key concepts needed to get real work done on UNIX systems. While readers with advanced backgrounds will prefer a book like "Mastering UNIX Shell Scripting" by Randal Michael, USP3E will please most UNIX scripting newbies.

USP3E begins with a review of the basics -- working with files and directories, redirecting input/output, pipes, and the shell itself. Chapter four's discussion of regular expressions is generally useful, although "saving matched characters" on p. 64 was confusing. This made the "command substitution" material on p. 129 unclear. Chapter six was devoted to the use of different sorts of quotes, which seems excessive until one realizes the significant differences between using single and double quotation marks in scripts. Attention to detail like this, along with generous inclusion of sample scripts, helped this book earn a strong rating.

While the book includes examples of using sed, awk is not mentioned. Sed could have received more coverage as well. While the authors direct interested readers to other books, perhaps a future edition might include chapters devoted to sed and awk? While the publisher's site doesn't mention a source for errata, it is available by contacting the authors.

Overall, I liked this book. It is up-to-date and compares favorably to the other books I consider reading to learn more about UNIX shell scripting. Armed with the knowledge gained from USP3E, readers should be equipped to automate some routine tasks. They will also be able to progress to more advanced shell scripting resources.

5.0 out of 5 stars Dated, but fantastic, May 31, 2001

This review is from: UNIX Shell Programming, Revised Edition (Paperback)

I am a perl and C programmer, and I am very familiar with the shells outlined in this book. So the material was not particularly "new" for me. I can see how it would be difficult to understand for a user who was new to shell programming.

If the intended audience is the intermediate unix user who knows something of programming, this book gets a full 5 star, my seal-of-approval rating. Terrific.

One thing it is lacking is a brief mention of perl or of awk. In many cases, it is simpler to write:

date | awk '{ print $2 }'

instead of:

date | cut -d' ' -f2

or, at least from the standpoint of understandability and readability. but the book doesnt claim to be a manual for awk, and oreilly has an excellent book on the subject.

I continually recommend this book to people, and where ever I go, I find this book on the bookshelves of successful people.

4.0 out of 5 stars First and only shell programming book I own, May 22, 1998

By 

Doug Alcorn ([e-mail]) (South Carolina) - See all my reviews

This review is from: UNIX Shell Programming, Revised Edition (Paperback)

I bought this book when it was originally published back in 1990. I started with little programming experience, and no shell programming experience. It brought me up to speed quickly. I no longer write many shell scripts; however, I still use it as a desk reference when I do. For any UNIX system administrator, this book (or one just like it) is essential.

BTW, I have been looking for a better book all these years and haven't found one. It's not that I think this book is perfect, rather there just aren't many good books on this subject.
