The Perl Programming Language - www.perl.org

Perl is a powerful text processing language known for its regular expression capabilities and practical extraction capabilities that revolutionized text processing on Unix systems. The language has influenced many modern programming languages and continues to be widely used for system administration scripting and bioinformatics where text processing is essential. Perl motto is There Is More Than One Way To Do It reflecting its philosophy of providing multiple approaches to solving problems. While Perl has been largely superseded by languages like Python for many tasks it remains important in legacy systems and sysadmin automation.
