free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by  the  kernel.  The  information  is  gathered by parsing /proc/meminfo. The dis‐
       played columns are:

       total  Total installed memory (MemTotal and SwapTotal in /proc/meminfo)

       used   Used memory (calculated as total - free - buffers - cache)

       free   Unused memory (MemFree and SwapFree in /proc/meminfo)

       shared Memory used (mostly) by tmpfs (Shmem in /proc/meminfo)

       buffers
              Memory used by kernel buffers (Buffers in /proc/meminfo)

       cache  Memory used by the page cache and slabs (Cached and SReclaimable
              in /proc/meminfo)

       buff/cache
              Sum of buffers and cache

       available
              Estimation  of  how  much  memory  is available for starting new
              applications, without swapping. Unlike the data provided by  the
              cache  or  free fields, this field takes into account page cache
              and also that not all reclaimable memory slabs will be reclaimed
              due to items being in use (MemAvailable in /proc/meminfo, avail‐
              able on kernels 3.14, emulated on kernels 2.6.27+, otherwise the
              same as free)
