DESCRIPTION
free displays the total amount of free and used physical and swap
memory in the system, as well as the shared memory and buffers used by
the kernel.
The -b switch displays the amount of memory in bytes; the
-k switch (set by default) displays it in kilobytes; the -m
switch displays it in megabytes.
The -t switch displays a line containing the totals.
The -o switch disables the display of a "buffer adjusted" line. Unless
specified free subtracts/adds buffer memory from/to the used/free memory

The -s switch activates continuous polling delay seconds apart. You
may actually specify any floating point number for delay,
usleep (3)
is used for microsecond resolution delay times.
The -V displays version information.
