2018-05-07 09:40:33 +0000 commented answer Tshark output incomplete in real time

yup Figured out same , last buffer it around 4kb.

2018-05-07 09:39:50 +0000 marked best answer Tshark output incomplete in real time

I ran following Commands :-

1) cat demo.cap | tshark -Tek -r - >> > outputs 8742 packets.

But when i try to tail the file....

2) tail -f -c +0 demo.cap | tshark -Tek -r - >> outputs 8672 packets.

3) tail -f -c +0 demo.cap | tshark -Tek -l -r - >> outputs 8672 packets.

On wireshark UI i get 8742 packets.

Interestingly if I use a capture of libcap format then and use -i instead of -r,

4) tail -f -c +0 demo.cap | tshark -Tek -i - > >> outputs 8742 packets.

it's apparent that, all packets are not seen, I realized Tshark might be buffering its output, but -l is not helping either. can anyone explain where else to look?
