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The shared memory column should be ignored; it is obsolete.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

These tools are probably obsolete and unportable. The command

syntax is poorly defined. Consider using the killall, pkill,

The default signal for skill is TERM. Use -l or -L to list available signals.

Alternate signals may be specified in three ways: -9 -SIGKILL -KILL.

Alternate signals may be specified in three ways: \-9 \-SIGKILL \-KILL.

System load averages is the average number of processes that are either

in a runnable or uninterruptable state. A process in a runnable state is
|
||||
either using the CPU or waiting to use the CPU. A process in
|

uninterruptable state is waiting for some I/O access, eg waiting for
|
||||
disk. The averages are taken over the three time intervals.
|
||||
Load averages are not normalized for the number of CPUs in a system, so
|
||||
a load average of 1 means a single CPU system is loaded all the time
|
||||
