CGI/Perl

CGI programs deliver a broad spectrum of content on the web starting from the mail-forms and counter programs to the most complex database scripts that generate entire websites on-the-fly.

Perl is a simple web language, easy to learn, yet powerful enough to accomplish the most difficult tasks. Widely available, Perl is an interpreted Language. You don not need to compile the script and run it. The Perl interpreter handles everything. This characteristic of Perl lets you to copy you script with little or no changes to any machine with a Perl interpreter. The only drawback of it is that you won’t discover any bugs in your script until you run it.

In CGI/Perl programming, you can use a text editor on your local machine and upload the finished scripts to the Unix Server. CGI/Perl files must be ordinary texts. CGI must be uploaded as text, and not as binary. Uploading it as binary would come across with a lot of control characters at the end of the lines, and these would break the script.

Perl Scripts, along with Unix commands and file names are all case sensitive. A programmer must keep this in his mind while he write Perl Scripts.
