Howdy list,

I've been wondering about this for a while:

How do I calculate the amount of free memory my system
has at any given point in time?

My top usually looks like this:

Mem: 72M Active, 668M Inact, 165M Wired, 29M Cache, 112M Buf, 70M Free
Swap: 2048M Total, 5448K Used, 2043M Free

I understand the "70M Free" part, but should I add "668M Inact" to
that? Or is it more complicated?

Thanks!
