Taking Bash to the next level

Linux system admin is something I do as part of my job. I've been able to acquire the basics and get the job done, but I knew that there were better ways to get the job done. Nothing like having an expert to help learn the ins and outs.

This book allowed me to take it to the next level. There are many excellent examples on how to get it done, as well as advice on things that should not be done.

There is a good mix of newbie info as well as useful tips for the seasoned veteran. There's usually more than one way to get the job done, and this book showed me some new, better ways to accomplish the task at hand.

If you're working with bash, you'll find something useful in this book.

These O'Reilly Cookbooks should be on every sysadmin's shelf. The Bash Cookbook is no different. Incredibly useful book. I didn't read it cover to cover but have gone back to it at least 15-20 times to pull out nuggets of info. The real-world, practical examples and solutions offered in this book provide the sysadmin with a virtual swiss army knife when working with bash.

Book was so useful, I bought two extra copies and sent them to coworkers.

What I've been waiting for!

This book is indeed a "Cookbook"; nice examples on how to do lots of stuff. It is nicely categorized and the explanations/discussions are easy to follow. The authors seem to have lots of experience, and are honest enough to even explain when NOT to use bash; when for example perl would do better.

Highly recommended if you want to get stuff done using bash.

Good collection of recipes. Covers bash 3.2

Currently this is the only book that specifically covers bash 3.2, the version that contain new and interesting features like =~ operator for "normal" regular expression matching.

The main advantage of the book that it really covers a lot of ground and provides system administrators and users with a lot of good and difficult to find tips about customizing of the environment and making yourself more productive.

Chapters 5-6 which provide good overview of new features introduced in version 3.x including "normal" regular expressions pattern matching ( operator =~) and C-style for loop. One problem with shells traditionally use two completely obsolete notations for regular expressions (basic regular expression often known as DOS-style regular expressions plus quite perverse prefix notation ). Bash 3.2 did not fixes this problem as this is a problem of Unix in general (Unix can be called an Os that uses a dozen of different definitions of regular expressions :-) that but at least added a normal regular expression notion to the list.

After chapters 5 and 6 I recommend reading chapters 9, 17 and 19 and then the rest. While chapters are of very uneven quality, usually you can find at least one useful tip in each.

The spectrum of bash related tips and useful mini-scripts is quote substantial. The authors cover classic things like customizing prompt quite well. The book is not only about bash it covers a lot of ground including use of classic Unix utilities in scripting (most notably grep, find, sort, and date) along with related topics such as use of pipes and I/O redirection.

Of course for such a complex topic there are some shortcomings. It's a pretty difficult task to write a good cookbook but authors did an excellent job and provided many very valuable tips that can help to improve both system administrators and power users productivity.

One of the problems for a cookbook is a good organization and specifically a good starting chapter and here authors failed. Some chapters are half-baked. The Chapter about version control is badly written and very superficial. The authors just mention a couple of system without any details. And in this topic the devil is in details.

Some bash features are explained superficially. For example bash has horrible implementation of pushd/popd/dirs troika and it not that easy to use them productively. One notable deficiency is that there is no way to suppress duplicates which in essence make this feature almost unusable. The authors treatment looks like a baseless advertizing of a poorly implemented feature.

But I hope that the authors will improve the book in the next edition and I am reluctant to downgrade the book based on those flaws. After all, this is a cookbook and it should be judged by the best recipes not the worst.

The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards.

"bash Cookbook" teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them.
