It’s a new year and already there’s another great review of my book Oracle Shell Scripting!

Gaadha wrote on Amazon

I am very happy the way this book is written. It’s very concise but covers all the major topics that an Oracle programmer needs to know.One thing that specifically interests me is that each chapter is very small..so you really feel like completing a chapter!Great Work!!!

As companies are cutting back on training and trying to do more with less I expect we’re going to start to see more interest in tech books again, especially ones like this that help you do more with less!

Well, things have been busy for me (hence the break from blogging) but interest in my Oracle Shell Scripting book remains strong! Just today this (5 star) review showed up on Amazon from Srinivas Gaddam:

Excellent presentation
If you are working on Oracle products, you know problems can get complex and the internet will have million possible solutions, but if you are looking for just one that works you should own this book.

Thanks a lot Srinivas! This comment hits on one of the reasons I wrote the book: to give a coherent but concise treatment of shell scripting for Oracle while giving plenty of usable scripts to get people started quickly!

Since the contents of variables will, well, vary it is often useful to be able to make decisions based on them. Strings and numbers can be easily compared to explicit values or other variables. Here is a simple example:

$ i=107
$ if [ $i -gt 100 ]
> then
> echo "Wow, i got all the way up to $i"
> else
> echo "i is only up to $i"
> fi
Wow, i got all the way up to 107
$ i=22
$ if [ $i -gt 100 ]
> then
> echo "Wow, i got all the way up to $i"
> else
> echo "i is only up to $i"
> fi
i is only up to 22

Here we see a simple if statement. When executed the expression within the brackets is evaluated to either true or false. If the expression is found to be true the commands after the then will be executed, otherwise the commands after the else are executed.

The expression shown here is the greater than expression (>). The symbols we typically use for greater than and less than have specific significance in the UNIX shell, so to compare values we use -gt for greater than and -lt for less than. Comparisons can also be made between strings of text. More information about comparing text and numbers can be found in my book.

My book, Oracle Shell Scripting has received another 5-star review on Amazon!

Oracle administrators of all levels will find benefit in this book. The author has put together the basics in shell scripting and OS fundamentals in aid of maintaining and monitoring scalable production Oracle environments. Each example is easy to read and follow and leaves the reader with room to explore and extrapolate on their own with little effort. A great lookup source for old timers and “must have” for newbies.

I highly recommend this book

Thanks for the great review Rat!
