Introduction to CGI/Perl Please use speaker notes for additional information!
First.cgi 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 (#). #!/usr/bin/perl #first.cgi print "Content-type: text/html\n\n"; #generate HTML print "<HTML>\n"; print "<HEAD><TITLE>First Script</TITLE></HEAD>\n"; print "<BODY><H1 ALIGN=CENTER>Hello World!</H1></BODY>\n"; print "</HTML>\n"; 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.
First.cgi The -c switch tells the perl interpreter to check the syntax of the script.
First.cgi You can see the HTML script that was generated as a result of using the -w switch with perl.
First.cgi Note that first.cgi is in the director C:\perl\bin which also contains the perl executable.
First.cgi Now I have uploaded first.cgi to my host and stored it in the directory named cgi-bin.
First.cgi This is the first.cgi script that I uploaded in the previous slide.
First.cgi Note that it says: http://www.pgrocer.net/cgi-bin/first.cgi
First.cgi Note that the source is the same code that was put into the script. #!/usr/bin/perl #first.cgi print "Content-type: text/html\n\n"; #generate HTML print "<HTML>\n"; print "<HEAD><TITLE>First Script</TITLE></HEAD>\n"; print "<BODY><H1 ALIGN=CENTER>Hello World!</H1></BODY>\n"; print "</HTML>\n";
