Forgive my naivety here I'm just trying to learn stuff and none of this is going into any production.

I have test.cgi :

use strict;
use warnings;
print "Content-type: text/html\n\n";
print "Test";
my @ret = `./runthis.pl`;
print length(@ret);
print $ret[0];

[download]

In runthis.pl I have:

use strict;
use warnings;
print "Hellow World";

[download]

Now, locally on my machine, if I run test.cgi as test.pl from the command line this gives @ret length as 1 and shows $ret[0] as hellow world. BUT on my apache server the array shows with a length of 1 but the output hello world doesn't show.

  1. Do I need to change the STDOUT on runthis.pl? If so how?
  2. Are there better ways to run a SAFE script as a cgi on apache and get its output into a variable? (The script is just going to output string/text)

Update:

In the end this is what worked with some trial/error suggestions from the good folk here

my @ret = qx(/usr/bin/perl ./runthis.pl`);
