{3} dmaze% free
             total       used       free     shared    buffers     cached
Mem:         47388      46280       1108      18440       1908      13340
-/+ buffers/cache:      31032      16356
Swap:       101216       6304      94912

I think the first number on the "-/+ buffers/cache" line is the number 
you're looking for.
