If Apache web server has installed in your system, you can run Perl/CGI script successfully. Create a html file and perl script using following steps.

Step 1: Creating a web page add.html

Open your console and type:

$ sudo gedit /var/www/add.html

Copy the lines below in the file and save it.

Addition of two numbers.

Step 2: Creating a perl script add.pl

Open your console and type:

$ sudo gedit /usr/lib/cgi-bin/add.pl
$ sudo chmod a+x /usr/lib/cgi-bin/add.pl

The command chmod a+x is used to allow permission to run the script. Without using this command your program will not run. !!!

Copy the lines below in the file and save it.

#!/usr/bin/perl -w
use CGI;
CGI::ReadParse();
$numb1 = $in{’n1′};
chomp($numb1);
$numb2 = $in{’n2′};
chomp($numb2);
$numb3=$numb1+$numb2;
CGI::PrintHeader();
print “content-type:text/html\n\n”;
print “\n”;
print “Addition of two numbers\n”;
print “\n”;
print “

Addition of $numb1 and $numb2 is $numb3.\n”;
print “\n”;
print “\n”;

Step 3: Running the program

Open web browser and hit address http://localhost/add.html to run the Perl/CGI program.
