Subject: Variable empty or not

Hi all,

I am doing some evaluating on a variable,
$Fw_Ip = %x[/usr/bin/plink -pw xxxxxx xxxx@xxxxxx "command" |grep
INACTIVE]

Now I want to do something depending on if the $Fw_Ip is empty or not.

if ($Fw_Ip != nil)
puts "Active"
else
puts "Inactive"
end

I guess that the variable is not empty so it will always return True but
if I  puts $Fw_Ip it is empty.

Suggestions on how to solve it would be much appreciated.
