in reply to Using backticks with (mount):

But, the return for:
$error = $! if $!; print $error;
should be the message error, but if an error occurred during the process, right?

At least, this was my intention...

btw, I am looking in the perlvar, as sugested, and I couldn't solve my doubt yet.

well, thank you! =)

    In brief-

    Don't look at the value of $! in the general case. Structure your error checking to only look at $! after detecting an error by other means. Usually that means after a call fails.
