Well I agree with Richard, OK proc filesystem gathers statistics ( anybody knows after
how much
time it polls for stat ).
In man of top, there is no reference to /proc/meminfo while in free it is
there...because man proc
also says that it
is giving you a visual aid for /dev/kmem(kernel data-structures).
Man of top only talks about a configuration file /etc/toprc
man of top describes it as :
top provides an ongoing look at processor activity in real time. It
displays a listing
of the most CPU-intensive
tasks on the system, and can provide an interactive interface for manipulating
processes.
It can sort the tasks by
CPU usage, memory usage and runtime. can be better configured than the
standard top
from the procps suite.
Most features can either be selected by an interactive command or by
specifying the feature
in the personal or
system-wide configuration file. See below for more information.
while description of free is :
free displays the total amount of free and used physical and swap memory in
the system, as
well as the shared memory and buffers used by the kernel.
I think now that top is doing for the processor ( related to tasks and processes )
while free goes
for memory works.
comments welcomed....I know I am too much on to the man pages.
