Can I use stdout in the script called form system()?

[NONAKA A. <an...@mi...>]

Hi,

I am trying to write my webmin module and have a question about perl
programming.

I have a test.cgi like below.

$ cat test.cgi

#!/usr/bin/perl
print "Content-type: text/html; Charset=iso-8859-1\n\n";

$| = 1;
print "foo<br>";
system("echo bar");
print "baz<br>";

If I run this script from shell, I works fine. But if run this script from
my web browser through Webmin, perl system() function will fail with
errno=13 and "bar" is not echoed.

If I change this test.cgi script like

system("echo bar > /dev/null");

system() will return 0.

I seems to me that I cannot use stdout in the script called from system()
under miniserv.pl.

Q1. Is this a bug?

Q2. Are there any work around? I want to write something to stdout  in the
script called from system(). Unfortunately , the script is not written in
perl.

Thanks in advance,
