Hi Jeffs,
Did you use the option -w outfile?
See tshark -h or the manpage:
http://www.wireshark.org/docs/man-pages/tshark.html
-w <outfile> | -
Write raw packet data to outfile or to the standard output if outfile
is '-'.
NOTE: -w provides raw packet data, not text. If you want text output
you need to redirect stdout (e.g. using '>'), don't use the -w option for
this.
Best regards
Joke
