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 mem‐
       ory 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       shared memory column should be ignored; it is obsolete.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 -V displays version information.

FILES
