tcpshark is a tcpdump-like utility, with an extra feature: it stores the process id, the command and the arguments as a trailer for each Ethernet frame. For now, only TCP and UDP Ethernet packets are supported.

Tested on recent versions of Linux, Mac and Windows.

libpcap or equivelant (npcap for Windows) is required.

The trailer can be parsed via the lua script tcpshark.lua, which can be added to wireshark's plugin system, or directly injected in each run via -X option in wireshark (look below for examples). There's also an excellent video on loading custom dissectors for Wireshark here:
