Perl may refer to any of the following:
1. 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 is already installed on the computer. However, if you're using macOS or Microsoft Windows, you need to download and install a Perl client. We recommend ActiveState or Strawberry for Perl, available from the links below.
