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

SYNOPSIS
       free [-b | -k | -m] [-o] [-s delay ] [-t] [-l] [-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  The shared memory column should be ignored; it is obsolete.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) 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.  If the -o option is not specified, free subtracts buffer
       memory from the used memory and adds it to the free memory 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 -l switch shows detailed low and high memory statistics.

       The -V switch displays version information.
