If you mean the UN*X "split", note that you'd need one with an option
such as "-b" that allows it to split binary files such as libpcap files,
*and* that none of the resulting files will be readable except for the
first, and that one will probably get an error when reading the last
packet as it will almost certainly have been split.  You'd have to have
whoever's reading the file glue the files back together with "cat".
