Subject: Check comand status in ruby

Hello,

How can I check comand status in Ruby ?
In perl I'm usually using something like that:

$cmd="mv $srcdir/$file $dstdir/$dstfile > /dev/null 2>&1";
$result=system($cmd);
$status=$result >> 8;
if ($status eq '0') {
  &Logit("Ok");
}
else {
  &Logit("Not Ok");
  &Logit("$!");
}

I have tried this code in Ruby but it does not working
as I wish:

IO.popen("/usr/bin/cd /tmp") { |process|
  result = process.gets
  if (result == nil)
    logToScreen "Ok"
  else
    logToScreen "Not Ok"
  end
}

Many thanx !
