Perl - Introduction
Practical Extraction and Reporting Language (PERL) is an open source server side programming language extensively used for web scripts and to process data passed via the Common Gateway Interface from HTML forms etc. Perl scripts are not embedded within HTML pages and do not download to the web browser but reside on the server. They execute by being triggered from commands within HTML pages or other scripts and may produce HTML output that does download to the web browser.
Perl is also commonly used to extract information from files. In fact, this is what perl was originally developed for. Perl was "born" in 1987 when it was released to usenet's alt.comp.sources by Larry Wall.
