use wireshark print output on cli

[balu KUMAR <balu_so () yahoo co in>]

Hi,

I have good hands on wireshark GUI. But now I want to use wireshark from command line, when capturefile and filter sent 
to wireshart it displays info on gui but I am trying to get output on cli.
My requirement is to get infor from wifi packets information elements. For example, I want to find packets with dtim 
period as 3 in beacons or TIM values or wmm paramets in data packets. This filters can be configured using CLI but out 
put opens in GUI. but I required it on stdout (cli). 
If we go for tcpdump or tshark I didn't get filters for those fields, these tools allows only type, subtyes and few 
other not all supported by wireshark.
I did search for cli output for wireshark but didn't find it. Can you please help me on this.
