NAME
       free - Display amount of free and used memory in the system

SYNOPSIS
       free [-b | -k | -m] [-o] [-s delay ] [-t] [-V]

DESCRIPTION
       free displays the total amount of free and used physical and swap memory in the system, as
       well as the buffers used by the kernel.  The shared memory column should be ignored; it is
       obsolete.

   Options
       The  -b switch displays the amount of memory in bytes; the -k switch (set by default) dis-
       plays 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.  If the -o option  is  not
       specified,  free subtracts buffer memory from the used memory and adds it to the free mem-
       ory reported.

       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.
