how run snort in quiet and deamon mode

[s m]

hello guys

i have a freebsd8.2 and wanna run snort on it. my snort version is
2.9.3.1. i want to run snort in deamon mode and quietly. man page says
that "D" flag is for running snort in deamon mode and "q" flag is to
run it quietly(do not show startup message). my problem is, these two
flag can not work together. when i run "snort -q -D" or "snort -D -q",
snort run in deamon mode but some startup messages are shown. when i
run "snort -q" no message is shown.

i know it is so simple issue but i do not know how to do that. any
hints or comments are appreciated.
