[PATCH 1/2] logger: warn when --file and command line message are combined

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When --file is combined with command line arguments the later has
silently been ignored.  This commit makes user to be aware the logger
will not use command line arguments when --file is specified.
