       free - Display amount of free and used memory in(1,8) the system

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

       free  displays the total amount of free and used physical and swap mem-
       ory in(1,8) the system, as well as the buffers  used  by  the  kernel.   The
       shared memory column should be ignored; it is obsolete.

       The  -b  switch(1,n)  displays  the amount of memory in(1,8) bytes; the -k switch(1,n)
       (set(7,n,1 builtins) by default) displays it in(1,8) kilobytes; the -m switch(1,n) displays it in(1,8)

       The -t switch(1,n) displays a line containing the totals.

       The -o switch(1,n) 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(1,n) 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(1,3,5) information.
