No such functionality exist today in tshark (it's a one-file-only-kinda-guy). The way I do what you want is:

mkdir tmp
for file in $(ls -1 *.pcap)
do
   tshark -r $file -w tmp/$file -R "!tcp.port==25)"
done
mergecap -w out.cap tmp/*
rm -rf tmp

Of course this can be optimized by saving this in a script which would do some error-checking to, etc.

Cheers,
