NAME
        free  - Display amount of free and used memory in the sys­
        tem
 
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 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
        from/to the used/free memory reports (respectively!).
 
        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.
