.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The shared memory column should be ignored; it is obsolete.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
The \fB-b\fP switch displays the amount of memory in bytes; the
\fB-k\fP switch (set by default) displays it in kilobytes; the \fB-m\fP
switch displays it in megabytes.
.PP
The \fB-t\fP switch displays a line containing the totals.
.PP
The \fB-o\fP switch disables the display of a "buffer adjusted" line.
If the -o option is not specified, \fBfree\fP subtracts buffer memory
from the used memory and adds it to the free memory reported.
.PP
The \fB-s\fP switch activates continuous polling \fIdelay\fP seconds apart. You
.SS OPTIONS
.TP
\fB\-b\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
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
Display the amount of memory in megabytes.
.TP
\fB\-o\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
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.
.PP
The \fB\-V\fP displays version information.
.TP
\fB\-t\fR
Display a line showing the column totals.
.TP
\fB\-V\fR
Display version information.
