Perl is an interpreted programming language originally developed by Larry Wall in 1987 for text manipulation and system administration tasks. It combines elements of C, shell scripting, and Unix system calls. Perl is useful for tasks like file parsing, text processing, CGI scripting, and database access. It runs on many operating systems and is freely available. The language uses scalar, array, and hash data types and includes control structures like conditionals and loops that are similar to C syntax. Perl can handle tasks like file input/output, regular expressions, and subroutines. Development is aided by its debugger and large collection of third-party modules.
