tshark: Difference between -R and -Y
From: Joerg Mayer <jmayer () loplof de>

Hello,

I just found out that I don't understand what -R does.

If I run
tshark -2 -R "udp.port==53" -i wlan0
then it seems that I see all packets (arp, dns, lldp, ...)
if I instead run
tshark -2 -Y "udp.port==53" -i wlan0
I only see dns.
The manpage is not helpful either to explain what I am seeing
(snv HEAD / r54612)

Can someone please explain what is going on here?

Thanks
    Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
