Generically speaking, you can feed the STDIN of a child process like so:

open my $fh, '|command' or die "Can't run command: $!";
print $fh "input for command\n";
print $fh "more input for command\n";
close $fh;

More specific to your situation, years ago, I wrote a simple script to copy STDIN to a file, then set up Lighttp to run that script as a CGI. Then I opened a HTML file, with the form I needed to fill, in a web browser, filled in the form and submitted. I then edited (a copy of) the resulting file to create a template. with thta, I could use a script to test my target CGI by inserting various values into the template and feeding the result to the CGI script similarly to my code snippet above.
