Sorry, I should have been more specific. The starting session lines all end with something like:

20090409 000122 - BD0 - Order 123 starting session with client 12 port 34
20090409 000123 - EF0 - Order 234 starting session with client 347 port 38
...

And both the client and port are dynamic values.

Yeah, I'm getting errors -- I'm running this under cygwin, so I don't have easy access to nawk.
