Capture Packets with Tshark tshark -i wlan0 -w capture-output.pcap Read a Pcap with Tshark tshark -r capture-output.pcap HTTP Analysis with Tshark Specified in the corresponding Arch Linux package.Use these as the basis for starting to build extraction commands.The syntax for capturing and reading a pcap is very similar to tcpdump.
