Perl stands for Practical Extraction and Report Language. Larry Wall, designer of Perl, regularly maintains and updates this Unix tool for writing programs. Perl has the power and flexibility of a high-level programming language, it does not need a special compiler and linker, and Perl is the scripting language that is used for CGI scripts.

Perl Functions
Perl Functions fall into two major areas: list operators and named unary operators. These differ in their precedence relationship with a following comma. List operators take more than one argument, while unary operators can never take more than one argument. This page contains about 100 Perl functions arranged by category, including functions for real @ARRAYs, functions for real %HASHes, input and output functions and functions for fixed length data or records.
