Basic feature of language is its rich opportunities to work with text, including work with regular expressions, built-in syntax. Pearl has inherited many features of the C language, AWK, scripting languages shells UNIX. Perl is also famous for a huge collection of additional modules of CPAN, located at http://www.cpan.org . Language name is an abbreviation which stands for Practical Extraction and Report Language - «practical language for data retrieval and reporting." Originally abbreviation five characters in this form coincides exactly with the English word pearl («Pearl"). But then it became known that such language exists (PEARL (English)), and the letter «a» removed.
The main advantages are the support for different language paradigms (procedural, object-oriented and functional programming styles), control of memory (without garbage collection, based on cycles), built-in word processing, as well as a large collection of third-party modules.
