Perl: not just for Web programming

Perl is sometimes perceived as a language limited to Web programming. However, Perl is a general-purpose programming language with many strengths, the biggest being in the area of string and data processing. Since most programs process strings or data or both, Perl works well for most programming, including system programming. It gives you access to C library functions for fine-grained control of files, processes, and network sockets, while at the same time handling the onerous details of low-level memory management and offering powerful built-in data structures. Perl also has advantages over other languages. It is much faster to write in than C, which makes it good for rapid prototyping. Perl can replace Unix shell scripting languages on Unix systems when you need to write a program quickly to do a small task. It is faster than most other scripting languages because it is compiled instead of interpreted. The author takes a quick trip through Perl and looks at some tiny but powerful code samples
