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The shared memory column should be ignored; it is obsolete.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