Item description for Minimal Perl: For UNIX and Linux People by Tim Maher...
A guide to a carefully designed subset of the Perl language, this book makes Perl more accessible to those having UNIX/Linux skill levels ranging from elementary to expert by capitalizing on their existing knowledge of important utilities (grep, awk), or essential concepts (filters, command substitution, looping). Dozens of detailed programming examples are shown, drawn from contemporary application areas such as system administration, networking, Web development, databases, finance, HTML, CGI, and text analysis. Broken into two parts, the first is for all who are familiar with core UNIX/Linux commands such as grep and caters to readers ranging from managers and administrative staff to advanced programmers. The second part is for developers experienced in Bourne, Korn, Bash, or POSIX Shell programming and makes Perl scripting easy to learn by showing Shell examples along with their Perl counterparts. Many Perl modules are covered including freely available pre-written code from the CPAN.

Reviews - What do customers think about Minimal Perl: For UNIX and Linux People?
Command Line Perl Feb 25, 2008
Minimal Perl focuses on translating UNIX/Linux shell commands to Perl (awk, sed, grep, and the like). It doesn't go into whole programs as much as single-use lines, which is fine for simple tasks like checking log files or filtering text files. There are a few conventional programs thrown in the book but all of them are very short. In fact, the comments generally outweigh the code. Don't take that as bad, though. Tim Maher introduces some great ideas that I haven't seen in the other Perl books I've read. It's a great reference to have on hand for simple tasks. Maher uses clear examples and clever text to get across some complex (and often difficult to read) Perl. If your looking for traditional programming book, this probably isn't for you. Stick with O'Reilly for how to write complete programs. Minimal Perl is all about quick and disposable code that's more powerful then shell commands but not the overkill of a complete program.
Great Perl Tutorial for Experience UNIX/Linux Users Jan 18, 2008
This is an excellent Perl tutorial for those who are already familiar with UNIX/Linux shell scripting and other common utilities like find, sed, grep, and awk. Perl combines the strengths of each of these tools and surpasses them in one powerful and portable scripting language. This book is well worth the time and money spent with it for those in its target audience. This book is very well written. The examples are easy to follow and well thought out. The author clearly has a deep knowledge and long experience with the material presented. He takes a very common sense and practical approach to teaching the essentials of Perl scripting without getting the reader bogged down in all the details and capabilities of the language. He seems to have done an excellent job in selecting those parts of Perl that are of the most use for the greatest number of people who need to make use of it. I highly recommend this book.
If you are a Sys Admin Oct 20, 2007
If you are an experienced Sys Admin in the Unix world and need to know enough Perl for scripting, this book is good - but its not a beginners book- the author expects you be familiar with command line Unix and scripting.
The unix way, perl style Sep 13, 2007
The cw tells you to not to use perl when traditional commands will do, but this book tosses that aside. It thoroughly covers several use cases where perl really does a better job. In addition, by switching from sed, grep, awk, and so forth completely to perl, you don't have to think as much of syntax stuff each time you run a command. One of the first things that sold me was eliminating the common stack of greps, and replacing it with a single line of perl.
The book is also well written and enjoyable. You should have some basic abilities in perl or unix/linux, but it provides a lot of introductory material that is specific to this book's idiom of minimal perl. If you have questions about the book, the publisher provides a forum to ask the author.
If you believe in the unix way, but are sometimes frustrated by whichever unix you use, or especially if you switch between unices, this book offers a way to cure that frustration.
Very Effective and Potent Jul 2, 2007
One thing I really loved about this book is that it is short and sweet, well written, clear. It covers extremely popular functionality (text search, text manipulation, column/field manipulation, file search) in Perl as it compares to the popular tools: grep, sed, awk, and find (including extended and GNU varieties). It documents how to do the equivalent in Perl, but also covers the advantages and disadvantages in doing these chores Perl. The coverage is really well written.
What really struck me personally, is that for a long time, I was baffled about why there was no simple way to extract columns or fields from fixed-width data. I used regular expression or split in Perl, which I thought was overkill. Unix has simple mechanisms using cut and awk for this, and after many hours scouring the net and published books, I couldn't find any coverage of a simple solution, until I came across this book.
If you do any automation on Unix (or even Windows) that requires extracting or manipulating text data, this book is an ultimate resource for your library. Anyone serious about Perl and/or system administration type of chores, should not pass this book up.
