Hi all, I would like to print the captured packet to standard oupout with epoch time formation. The command I used is: tshark -i 1 -n -f "udp port 8080" -t e -T fields -e frame.time -e XXXXXX > /tmp/my_tshark_data.$(date +%F-%T) The parameter "-t e" seems not to take effect. What should I do? Thanks in advance Best Regards, Ian
