Oracle Shell Scripting: First Review on Amazon.com

Last week my book, Oracle Shell Scripting: Linux and UNIX Programming for Oracle got its first review on Amazon.com:

Here’s Mike Bennett’s complete review from Amazon:

I’m a veteran Oracle Database Administrator and most of my work is on Unix systems so I wasn’t sure how much information in this book would be useful to me. I was pleasantly surprised to find what a wide range of scripting tips and techniques this manual provides. I was impressed by the fact that the author didn’t just describe HOW to do something, but also explained WHY a particular approach was taken. I also like the fact that the scripts given aren’t just contrived samples, but are practical and useful as given. This information will definitely help simplify some of my routine tasks and provide me with timely information about the environments and systems I work with. The author also pointed out how to go beyond what was provided in the book by suggesting ways the examples might be modified. I’ve already taken advantage of that with a script I helped one of my clients develop.

Thanks to Mike for the great review! I’m glad he found the book useful and I hope others do as well. If you have my book I welcome your feedback and encourage you to post your own review on Amazon!

When to use shell scripts

With my new book “Oracle Shell Scripting” now on shelves you may be wondering what shell scripting can do for you. Below is an excerpt from the book that touches on when you may want to think about scripting. While the book is geared toward Oracle users much of the content would apply to shell scripting regardless of the use.

When to script

A shell script can be written to do anything you would do at the command line. So when do you want to write a shell script? When is it a bad idea? Well, here are a few guidelines I use.

Shell scripts can yield the biggest return on regular tasks that are performed more-or-less the same way each time. If every day you log into a system and remove some files out of a directory, backup a database or check a log file for a specific string of characters you should automate these tasks. Chances are you can make them run automatically and save yourself the hassle all together.

Shell scripts aren’t just for automation though. In some cases a script saves us time in a different way by allowing us to run a simple command instead of a very complicated one.

One of the most powerful features of the shell and shell scripting is the ability to affect several files and even multiple servers with a single script. Loops and commands like find make shell scripting ideal for managing large numbers of files in a single step.

In general there is little point in writing a shell script to do something once. The exception to this is occasionally something needs to be run at a time when you would rather not have to be around to run it yourself. In this case you may decide to bundle those commands into a shell script and schedule it to run without you involved. Be careful with this type of script and always be thinking “what if something goes wrong?” because sooner or later it will and if you’re not around to fix it you could get in some hot water.
