Output of "free -m" doesn't match

Question

How can I check my RAM usage? I am trying the command free -m as I saw here, I should get something like this:

              total      used       free     shared    buffers     cached
Mem:          3699       2896        802          0        247       1120
-/+ buffers/cache:       1528       2170
Swap:         1905         62       1843

But when I try this command I can't see the line: -/+ buffers/cache: 1528 2170

I always get:

               total        used        free      shared  buff/cache   available
Mem:           7903        2395         142         341        5365        4710
Swap:          6541          21        6520

So, where I can see my free and used RAM?

The updated free -m output is different from the referenced 2010 post you pointed at.

The 'Available' value is the one you want to look at; it takes into account the buffers and cache now. So in your system, you have 4710MB of memory available out of 7903MB of available memory on your system.
