(Ebook) Minimal Perl: For UNIX and Linux People by Tim Maher ISBN 9781932394504, 1932394508

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.Perl is a complex language that can be difficult to master. Perl advocates boast that "There's More Than One Way To Do It", but do you really want to learn several ways of saying the same thing to a computer?To make Perl more accessible, Dr. Tim Maher has over the years designed and taught an essential subset of the language that is smaller, yet practical and powerful. With this engaging book you can now benefit from "Mininal Perl" even if all you know about Unix is grep.In Minimal Perl, you will learn how to write simple Perl commands (many just one-liners) that go far beyond the limitations of Unix utilities, and those of Linux, MacOS/X, etc. And you'll acquire the more advanced Perl skills used in scripts by capitalizing on your knowledge of related Shell resources. Sprinkled throughout are many Unix-specific Perl tips.what's inside• A simpler, yet still powerful Perl• Development of concise commands and flexible scripts• How to package custom software in reusable modules• How to exploit CPAN modules to avoid reinventing the wheel• Language features in tabular summaries• 100+ reusable programs for: system administration, web development (HTML, CGI, Forms), networking, databases, finance, text analysis, and more
