Basic tshark usage
$ tshark -r file.pcap -T fields -e data.data -Y "icmp && ip.src == 192.168.1.7"
$ tshark -r file.pcapng -T fields -e dns.qry.name -Y "ip.addr == 18.217.1.57 && dns"
-r: file
-Y: filter
-e: extract certain fields
-T: format of text output (required for -e; fields option outputs only the field value)
