It's OK, you used system. My backticks were met with revulsion. :-)

    I'll see your revulsion and raise you a silent bug. The above used system without separating the arguments, or checking return value. The perldoc shows better practice. If you're writing immutable code on your own box, you can obviously shove it all into one string but it's not a habit to cultivate.

    my @args = qw( perl ); system(@args) == 0 or die "system @args failed: $?"
