FREE(1)			      Linux User's Manual		       FREE(1)

NAME
       free - display information about	free and used memory on	the system

SYNOPSIS
       free [-b|-k|-m|-g] [-l] [-o] [-t] [-s delay ] [-c count ]

DESCRIPTION
       free(1)	displays the total amount of free and used physical memory and
       swap space in the system, as well as the	buffers	and cache consumed  by
       the kernel.

OPTIONS
       Normal invocation of free(1) does not require any options.  The output,
       however,	can be fine-tuned by specifying	one or more of	the  following
       flags:

       -b, --bytes
	      Display output in	bytes.

       -k, --kb
	      Display output in	kilobytes (KB).	 This is the default.

       -m, --mb
	      Display output in	megabytes (MB).

       -g, --gb
	      Display output in	gigabytes (GB).

       -l, --lowhigh
	      Display detailed information about low vs. high memory usage.

       -o, --old
	      Use old format.  Specifically, do	not display -/+	buffers/cache.

       -t, --total
	      Display total summary for	physical memory	+ swap space.

       -c n, --count=n
	      Display statistics n times, then exit.  Used in conjunction with
	      the -s flag.  Default is to display only	once,  unless  -s  was
	      specified, in which case default is to repeat until interrupted.

       -s n, --repeat=n
	      Repeat, pausing every n seconds in-between.

       -V, --version
	      Display version information and exit.

       --help Display usage information	and exit
