While doing a CGI file that mount's and umount's devices in a linux computer, I tried to use:

$example = `mount`;
$example = $! if $!;

print $example;
[download]

But the answer to the "print $example;" was an "illegal check" message!
I looked really hard, but I didn't find the error, or something that would cause the error message.

My major doubt is that the "cgi" is working errr... "properly", but the error message insists to appear!
So, i did the test:

$example = `mount`;
$error = $! if $!;

print $example;
print $error;
[download]

And the "print $example;" returned the expected answer, but the "print $error;" returned the same "illegal check" message.

If anyone could help me to solve this problem, I'ld be really gratefull!
Thanks a lot!
