Quicky here. I'm processing logs do not necessarily know the MAC's of IP's
I'm looking to find usage for. Right now I'm doing this:
$Usage{$MAC}=0 if ( ! $Usage{$MAC} );
$Usage{$MAC}=$Usage{$MAC}+$NewUsage;
I could have swore there was a way to say something along the line of just
set $Usage{$MAC} to Zero if it's not defined. Without turning off warnings
is my goal.
Anyone know a better or cleaner way to do this?
