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

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

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	The shared memory column should be ignored; it is
       obsolete.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     Display the amount of memory in bytes.

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

       -g     Display the amount of memory in gigabytes.

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

       -l     Show detailed low and high memory statistics.

       -m     Display the amount of memory in megabytes.

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

       -s     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.

       -t     Display a line showing the column totals.

       -V     Display version information.
