What means LWP column in the "top" command? Number of threads?
Peter Hanke
One of the output columns are labelled "LWP" .
What does that column mean? Is this the number of threads inside the process?

I don't have that. How did you get it?

Wikipedia says it means light weight process,

"LightWeight Process id" http://www.unixtop.org/man.shtml
It is the thread id for the thread within the process, in a multi-threaded
process.
"The display of individual threads can be toggled with the synonymous
commands t and H. Information about state, priority, CPU time and per-
cent CPU are shown for each individual thread. Other information is
identical for all threads in the same process. In this display the
column LWP replaces NLWP and shows the lightweight process id. The
column names LWP and NLWP are consistent with ps(1)."

Press the slash key, '/', and search for "columns".

At any given moment, an arrow must be either where it is or where it is
not. But obviously it cannot be where it is not. And if it is where
it is, that is equivalent to saying that it is at rest.
