Use CGI.pm!! 
use strict;
use CGI;

my $CGI = new CGI;

print $CGI->header, $CGI->start_html, $CGI->pre;

foreach my $name ($CGI->param) {
    print "$name = ", $CGI->param($name), "\n";
}

UPDATE: (an explanation)

When a form is submitted to a Perl script that uses CGI.pm, the form variables are magically available via the param() method.

The param() method works two ways: when called with no args, it returns a list of the available form variables. When called with a single argument(the name of the form variable you want the value of) it returns the value of that variable.

The big gotcha is dealing with multiple-valued variables, then param() will return a list of the values. Change the line inside the for loop to this: 

    my $value = join(",", $CGI->param($name)) || ''; 
    print  "$name = $value\n";

if you want to handle multiple-valued variables. Otherwise the script will only print the last assigned value. Jeff
