The use of grep -v will work as long as the tcpdump output is limited
to one line per packet. However, some of the tcpdump options produce
multiple lines per packet. Those will appear to be jumbled as the
initial line for the packet will not be included but the following
lines will. The best approach to using tcpdump in these situations
is to use the -w option to write the raw data to a file. Then use
the -r to read it back in and filter using the tcpdump filters which
do include the not function. That way if you don't get what you
need, you can try again on the same data.
