I'm guessing you're trying to capture the output of one program and print it. you can do it with backticks:

$output=`cgi-bin/test.pl`;
[download]

which will capture the STDOUT of the test.pl, and put it in the variable $output. Another option is to use system:

system("cgi-bin/test.pl");
[download]

which will run the program, passing it the current processe's STDOUT and STDERR.
