Perl is a language for getting your job done.Of course, if your job is programming, you can get your job done with any "complete" computer language, theoretically speaking. But we know from experience that computer languages differ not so much in what they make possible, but in what they make easy.

At one extreme, the so-called "fourth generation languages" make it easy to do some things, but nearly impossible to do other things. At the other extreme, certain well known, "industrial-strength" languages make it equally difficult to do almost everything. Perl is different. In a nutshell, Perl is designed to make the easy jobs easy, without making the hard jobs impossible.

And what are these "easy jobs" that ought to be easy? The ones you do every day, of course. You want a language that makes it easy to manipulate numbers and text, files and directories, computers and networks, and especially programs. It should be easy to run external programs and scan their output for interesting tidbits. It should be easy to send those same tidbits off to other programs that can do special things with them. It should be easy to develop, modify, and debug your own programs too. And, of course, it should be easy to compile and run your programs, and do it portably, on any modern operating system.

Perl does all that, and a whole lot more.
