I prefer the --quiet option, so will go with that (principle of least surprise). In the case of debdiff, I'm not sure what the exit code would mean: would it mean that the file lists are different, that the control files are different, that there was some difference or what? Given the nature of debdiff, one would usually expect some sort of difference. Julian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
