Perl is unique, open-source language. Initially used for quick, disposable "macros" on UNIX systems, Perl has been ported to nearly every existing version of UNIX. It has been also been ported to 32-bit Windows several years ago, making Perl one of the few "compile-free", cross-platform languages available.
Since over two million people now develop in Perl, applications now are not only simple batch commands, but encompass web-based CGI development and mission-critical deployments.
I hope you all enjoy Perl as much as I do. It is an extremely powerful language full of capability. Don't forget, as you begin to think you have mastered Perl, you will find that there is even more yet to learn.
