Is this output untruncated?

You would only notice this with du if the nfs directory is unmounted. Unmount it and ls -al /usr/mountpoint should only give you an empty dir. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
