Sample usage:
``
sudo tshark -f 'host 192.168.1.102
``
This produces simple one liners for each request.

What you likely want is the `-V` option which fully disassembles each frame much as you can do in the <GUI> <Wireshark>:
``
sudo tshark -V -f 'host 192.168.1.102
``

Capture by instead:
``
sudo wireshark -f http -k
sudo wireshark -f icmp -k
``

Filter by both protocol and host:
``
sudo wireshark -f 'host 192.168.1.102 and icmp' -k
``

For <application layer> capture filtering, the best you can do is by port:
``
sudo wireshark -f 'tcp port 80'
``
There is an `http` filter but only for as a <wireshark display filter>
