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

SYNOPSIS
       free [options]

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 represents either the MemShared value (2.4 series
       kernels) or the Shmem value (2.6 series kernels and later)  taken  from
       the  /proc/meminfo  file.  The  value is zero if none of the entries is
       exported by the kernel.

OPTIONS
       -b, --bytes
	      Display the amount of memory in bytes.

       -k, --kilo
	      Display the amount of memory in kilobytes.  This is the default.

       -m, --mega
	      Display the amount of memory in megabytes.

       -g, --giga
	      Display the amount of memory in gigabytes.

       --tera Display the amount of memory in terabytes.

       -h, --human
	      Show all output fields automatically scaled  to  shortest	 three
	      digit  unit and display the units of print out.  Following units
	      are used.

		B = bytes
		K = kilos
		M = megas
		G = gigas
		T = teras

	      If unit is missing, and you have petabyte of RAM	or  swap,  the
	      number  is  in  terabytes	 and columns might not be aligned with
	      header.

       -c, --count count
	      Display the result count times.  Requires the -s option.

       -l, --lohi
	      Show detailed low and high memory statistics.

       -o, --old
	      Display the output in old format, the only difference being this
	      option will disable the display of the "buffer adjusted" line.

       -s, --seconds seconds
	      Continuously  display  the  result delay seconds apart.  You may
	      actually specify any floating point number for delay,  usleep(3)
	      is used for microsecond resolution delay times.

       --si   Use power of 1000 not 1024.

       -t, --total
	      Display a line showing the column totals.

       --help Print help.

       -V, --version
	      Display version information.
