how to extract data from pcap file
<p>I have a few pcap files, I can see the memcache protocol in wireshark and its corresponding data, but when I use tshark to batch export data, it only shows one character(0x0b), why? </p>

<p>the command I use: tshark -Y "memcache contains set" -r input.pcap -T fields -e memcache.value 
Thank you! 
BTW, memcache key works fine. And I can't share the files here as they are confidential. </p>
