Memory : free–m/-h

• actual memory consumption: used-buffers-cached namely total-free-buffers-cached
  • actual available Memory: Buffers+cached+free

• -buffers/cache Memory:( equal to used-buffers-cached of line 1 )
  • +buffers/cache Memory : + ( equals 1 lines of free + buffers + cached)

The visible -buffers/cache reflects the memory that is actually eaten by the program, and +buffers/cache reflects the total amount of memory that can be appropriated .
