Wireshark experts,
Probably a dump question but is there a concept of display filter without using wireshark GUI? Meaning that I'm capturing traffic using dumpcap using some capture filter. Is there a way to filter further (like a display filter) without loading the .pcap file in the wireshark? I'm interested in locating a byte series (e.g. 04 02 FF 01 32)in the capture files. I know how to do this in wireshark but am wondering if there is a way to do this using someother tool so that I can use some kind of script to determine if the capture files contain this series intead of load each capture file in wireshark and applying the display filter. I also tried using tshark's option of saving the capture file in ascii format and looking for a series but it breaks down if the bytes are spread across multiple lines.
TIA,
Sean
