Command line:-     wireshark -i  \Device\NPF_{52EFAA93-34C5-4F7E-80AE-638A48E3F1BD} -k -f  UDP

but I want something like

Command line:-     wireshark -i  \Device\NPF_{52EFAA93-34C5-4F7E-80AE-638A48E3F1BD} -k -f  UDP contains my_protocol

so that only my_protocol gets sniffed.

Can you show us the command-line you are using?

A pcap filter? You mean a capture file? The pcap/capture filter syntax does not provide a 'contains' keyword, so it's not possible. You can only use 'contains' in the display filter syntax, which is unique to wireshark (and tshark, etc.)

yes i am using 'contains' keyword, and i am giving name of my protocol which is a string.....
i am running it on Windows and i used 'udp contains my_protocol' also but its not working.......

i need to give filter expressions defined by pcap, but i am not getting any documentation of it.

You're really using the "contains" keyword? That's for strings and
binary strings.

The spaces in your filter are probably confusing the shell when you
invoke wireshark/tshark from the command-line. Are you running on
Unix? Use single quotes around your filter:

tshark ............ 'udp contains xxx'
