unbuffered tcpdump

tcp(){ tcpdump -nUs0 -w- -iinterface $1|tcpdump -n${2-A}r- ;} usage: tcp '[primitives]' [X|XX]
Sometimes the question comes up: How to get unbuffered tcpdump output into the next program in the pipe? i.e. if your OS forces you to wait for the buffer to fill before the next program sees any of the output If you use -Uw- then you can't use -A (or -X or -XX) at the same time. When the question comes up, I've never seen anyone suggest this simple solution: chaining 2 tcpdump instances.
