DESCRIPTION
free displays the total amount of free and used physical
and swap memory in the system, as well as the shared mem
ory and buffers used by the kernel.
Options
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
