Hi all,

I want to use tshark -T and -e to extract data from PCAP file. Some of the data are ipv4 data, some are ipv6 data.

I'm using this line now:

tshark -r test.pcap -T fields -e frame.number -e eth.src -e eth.dst -e ip.src -e ipv6.src -e ip.dst -e ipv6.dst -e frame.len -E header=y -E separator=, > test1.csv

then there would be empty fields in test1.csv, since the ipv4 data won't have ipv6.src and ipv6.dst.

Is there a way to select ip.src or ipv6.src, like -e "ip.src or ipv6.src"

Nothing like -e "field_1 or field_2" exists for a generic case, but in your particular one, -e _ws.col.Source should output either ip.src or ipv6.src, depending on their presence in the frame. I have no clue which one is output if both are present in the same frame, though.
