Actually, you do risk data loss by copying and then truncating. It is possible for the daemon to write additional data to the log between the time your copy completed and the truncation occurs. If you are dealing with log files, use 'logrotate' to manage the rotation of them. Ideally, though, the daemon will close and reopen the log file when rotation is performed (ie when signalled by logrotate). -D -- If your life is a hard drive, Christ can be your backup. www: http://dman13.dyndns.org/~dman/ jabber: dman@dman13.dyndns.org
