The Perl Reference Guide

The Perl Reference Guide

This free Perl book contains a concise description of all Perl statements, functions, variables and lots of other useful information. The purpose of the Reference Guide is to aid in the use of Perl, to look up the syntax of specific functions, statements and the meaning of built-in variables.


It is not a self-contained user guide – basic knowledge of the Perl language is required. It is not complete – some of the more obscure variants of perl constructs have been left out. But all functions and variables are mentioned in at least one way they can be used.
