tshark

I am in stuck in a situation where an interface will be captured more than one time. Like :-

$ tshark -i rpcap://1.1.1.1/lo -f "ip proto 1" -i rpcap://1.1.1.1/lo -f "ip proto 132"

or

(same filter) $ tshark -i rpcap://1.1.1.1/lo -f "ip proto 1" -i rpcap://1.1.1.1/lo -f "ip proto 1"

what will happen in both the cases ? In first case, will the capture filter gets OR'ed or AND'ed ?? In second case, will the same packets be captured two times ?

Is there any way to save Wireshark capture options? So it can be reuse after restart Wireshark. Also, if the saved file is in plain text, it's possible to use scripts generating bunch of capture settings, such with different filter setting. Does anyone know? Thanks. >>> More
