tshark: ":" was unexpected in this context
When I use TShark (Wireshark) 4.0.4 (v4.0.4-0-gea14d468d9ca) to filter 'frame.protocols == raw:ip:udp:data' with following cli,
"tshark -r 1.pcap -t ad -Y "frame.protocols == raw:ip:udp:data" -w 2.pcap"
the error msg appear.
tshark: ":" was unexpected in this context.
frame.protocols == raw:ip:udp:data
^
Please note that, I can use frame.protocols == "raw:ip:udp:data" to get filter result in Wireshark UI. How can I filter result result with tshark?
