[Bro] redef script variable from bro command line

[Frank Meier]

Hi!

This is just a minor problem, but I would still like to understand, why
it does not work. I am trying to set the log rotation from the command 
line. It works when I use the -e flag:

# bro -r 2009-m57.00.pcap -e "redef Log::default_rotation_interval = 20min"

It does not work, if I set the variable at the command prompt:

# bro test.bro -r 2009-m57.00.pcap rotation=20min
20.0 min
10.0 min

test.bro:

global rotation = 10min &redef;
redef Log::default_rotation_interval = rotation;

event bro_init() {
	print(rotation);
	print(Log::default_rotation_interval);
}

I suppose the reason for this is the order in which variables are initialized.

Can someone please explain?

Thanks!
