Use backticks to get output from an executed program. Check $? for the error returned.

A pipe would work in this case, but backticks are probably simpler.

    Update: I got confused between $? and $!. Sorry
    Hi

    I suspect that we can not rely on $? alone.
    From this perlmonks post
    $! having a non-false value is not an indication anything is wrong.

    BR,
