I have a capture file, want to use tshark to filter packets and write a new file.

When I use

tshark -r all.cap -w filtered.cap -R udp contains "100"

'I'm getting

tshark Read filters were specified both with "-R" and with additional command-line arguments

Platform is XP with SP2. What I'm doing wrong?
