I want to know how much memory I've got free on my system.

The free command gives me something like this:

             total       used       free     shared    buffers     cached
Mem:       2064832    2046196      18636          0     146892    1736968
-/+ buffers/cache:     162336    1902496
Swap:      2040244      12180    2028064

It would make sense to me that the kernel is sucking up most of my memory
into a bunch of unused buffers and that I actually have a lot more than 18
megs of free memory.  Is this the correct interpretation of these numbers?
What is the best way to get a good idea of how much memory I actually have
free on my system.
