 .SH DESCRIPTION
 \fBfree\fP 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 The shared memory column should be ignored; it is obsolete.
 .SS OPTIONS
 .TP
-\fB\-b\fR
+\fB\-b, \-\-bytes\fR
 Display the amount of memory in bytes.
 .TP
-\fB\-c\fR \fIcount\fR
-Display the result \fIcount\fR times.  Requires the \fB\-s\fR option.
-.TP
-\fB\-g\fR
-Display the amount of memory in gigabytes.
-.TP
-\fB\-k\fR
+\fB\-k, \-\-kilo\fR
 Display the amount of memory in kilobytes. This is the default.
 .TP
-\fB\-l\fR
-Show detailed low and high memory statistics.
-.TP
-\fB\-m\fR
+\fB\-m, \-\-mega\fR
 Display the amount of memory in megabytes.
 .TP
-\fB\-o\fR
+\fB\-g, \-\-giga\fR
+Display the amount of memory in gigabytes.
+.TP
+\fB\-\-tera
+Display the amount of memory in terabytes.
+.TP
+\fB\-h, \-\-human\fP
+Show all output fields automatically scaled to shortest three
+digit unit and display the units of print out. Following units
+are used.
+
+.nf
+  B = bytes
+  K = kilos
+  M = megas
+  G = gigas
+  T = teras
+.fi

+Display the result \fIcount\fR times.  Requires the \fB\-s\fR option.
+.TP
+\fB\-l, \-\-lohi\fR
+Show detailed low and high memory statistics.
+.TP
+\fB\-o, \-\-old\fR
 Display the output in old format, the only difference being this option
 will disable the display of the "buffer adjusted" line.
 .TP
-\fB\-s\fR
+\fB\-s, \-\-seconds\fR \fISECONDS\fR
 Continuously display the result \fIdelay\fP seconds apart. You
 may actually specify any floating point number for \fIdelay\fP, 
 .BR usleep (3)
 is used for microsecond resolution delay times.
 .TP
-\fB\-t\fR
+\fB\-\-si\fP
+Use power of 1000 not 1024.
+.TP
