This tutorial/reference aims to provides one complete, organized guide for UNIX programmers and users who want to learn Perl as quickly, and as easily, as possible. It assumes some basic programming experience, and some experience with UNIX shell languages, but does not assume that readers are C language experts or systems gurus. It demonstrates each function and new point with concise sample programs and output; concludes each chapter with simple C, shell, or awk scripts that compare to the Perl statements just covered; and features an actual application of Perl that incorporates all concepts presented.
