Hey Jeff,

Sorry for the confusion and thanks for the immediate response. I got it. I was exactly searching for this :)

tshark -r sim_venom_sanity_DEVICE1_PORT1_1_capture.pcap -Vx -R frame.number==2 | sed -n 's/^[0-9a-f]\s((\s[0-9a-f][0-9a-f]){1,16}).$/\1/p'

tshark -x will display a complete hex dump of the packet. Is that what you're looking for?

Sorry, I'm not sure what you mean. Do you want to only print the hex dump when it matches that particular pattern?

Or do you want to only print the hex dump of a certain field? Or of a certain protocol?
