I need to filter a certain packets from a set up capture files (100 files) and write them to a 
.pcap capture fle.

I'm not sure how to do this (but I hope there's an easy way).

Does this work?  [for each file] "tethereal -r ... -R ... -F ... -w- >> foo.pcap"

or must I write a separate output file from tethereal for each input file and use mergecap ?

or what ?


TIA
