Make STDERR readable as STDOUT
Hi all. I am trying to use backticks in Perl to put STDERR into a string. The code is...

Code:
$readkey_test = `perl -MTerm::ReadKey -e 1`;
print $readkey_test;

if ($readkey_test =~ m/[[:print]]/)
{
	print "ReadKey not installed...\n";
}
else
{
	print "ReadKey installed...\n";
}

If it comes up with an error, then it will return "ReadKey not installed", but if it comes up with no output whatsoever, then it will return "ReadKey installed". That's what it's supposed to do anyway...

I've tried putting 2>&1 at the end to turn STDERR into STDOUT but no dice...

Any ideas?

Maybe it wrote /dev/tty.
