Thanks to everyone for the kind words and encouragement. It's been very gratifying. Now I have a good number of suggestions, and a handful of bugs to fix!

Thanks for the suggestion, I'll put that on my todo list!

Cool thanks for the work! I'll try it out once the formula is released :) (Note: I am a different person)

I tried to brew install it as well. Would definitely like to see this formula available.

hi isostatic - sorry for the trouble :( I had hoped that compiling it would be quick and reliable. By default termshark will be installed in ~/go/bin/ - though it sounds like you have it compiled, it's just not running. Send me a message if you like and I'll see if I can get it working for you. There are also pre-compiled binaries at https://github.com/gcla/termshark/releases

As an old fart I expect to type "./configure; make", however it did seem to compile.

It runs, just doesn't look like it's reading anything from "sudo ./termshark -i eno1 icmp". Works fine when reading a pcap file, works fine when launching from a root session (rather than via sudo)
