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

       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       shared memory column should be ignored; it is obsolete.

       -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 disable 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.
