Perl in a Nutshell

Written By pcbolong on Sunday, November 6, 2011 | 5:51 AM

Computer languages differ not so much in what they make possible, but in what they make easy. Perl is designed to make the easy jobs easy, without making the hard jobs impossible. Perl makes it easy to manipulate numbers, text, files, directories, computers, networks, and programs. It also makes it easy to develop, modify, and debug your own programs portably, on any modern operating system. Perl is especially popular with systems programmers and web developers, but it also appeals to a much broader audience. Originally designed for text processing, it has grown into a sophisticated, general-purpose programming language with a rich software development environment complete with debuggers, profilers, cross-referencers, compilers, interpreters, libraries, syntax-directed editors, and all the rest of the trappings of a "real" programming language. There are many reasons for Perl's success. For starters, Perl is freely available and freely redistributable. But that's not enough to explain the Perl phenomenon, since many other freeware packages fail to thrive. Perl is not just free; it's also fun. People feel like they can be creative in Perl, because they have freedom of expression.
