The reason for the massive file size was my haste in running out of the
office on Friday and forgetting to kill the tcpdump process before the
weekend began.
Sounds like you may want a Perl script to automate managing your
tcpdumps.
99% of the time I use tcpdump for less than one minute to
Check out Tie::File on CPAN. This Perl module treats every line in a
file as an array element, and the array element is loaded into memory
when it's being requested. In other words: This will work great with
huge files such as these, as not the entire file is loaded into memory
at once.

Hi all,
I've got a 28GB tcpdump capture file that I need to (hopefully) break
down into a series of 100,000k lines or so, hopefully without the need
of reading the entire file all at once.
I need to run a few Perl processes on the data in the file, but AFAICT,
doing so on the entire original
