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 memory in the system, as well as the buffers used by the kernel.  The
       shared memory column should be ignored; it is obsolete.

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.

FILES

       /proc/meminfo
	      memory information
