1. Short for Practical Extraction and Reporting Language, Perl is an interpreted, free, open source programming language first developed by Larry Wall in 1987. It is very similar in structure to the C language. Perl is one of the more commonly used languages in writing CGI scripts and programming for Internet and web page applications. Below is an example of a Perl script that prints "Hello World!".
print "Hello World!\n";
If you're running a Linux distro, often Perl will already be installed on the computer. However, if you're using MacOS or Microsoft Windows, you'll need to download and install a Perl client. We recommend ActiveState or Strawberry for Perl, found on the links below.
