This is the shebank line. It contains the sharp symbol (#) followed by the bang symbol (!) and then the location of the Perl interpreter on the system that you are using.
Perl comments begin with the sharp symbol (#).
The print function specifies that the type is text/html because this code sends an HTML document.
The rest of the prints are sending the HTML which will be run.
The -c switch tells the perl interpreter to check the syntax of the script.

You can see the HTML script that was generated as a result of using the -w switch with perl.

Note that first.cgi is in the director C:\perl\bin which also contains the perl executable.

Now I have uploaded first.cgi to my host and stored it in the directory named cgi-bin.
First.cgiFirst.cgi
This is the first.cgi script that I uploaded in the previous slide.

Note that the source is the same code that was put into the script.
