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shared memory column should be ignored; it is obsolete.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.
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.
