.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility prints a summary of the current activity on the system,
|
||||||
|
including what each user is doing.
|
||||||
|
The first line displays the current time of day, how long the system has
|
||||||
|
been running, the number of users logged into the system, and the load
|
||||||
|
averages.
|
||||||
|
The load average numbers give the number of jobs in the run queue averaged
|
||||||
|
over 1, 5, and 15 minutes.
|
||||||
|
.Pp
|
||||||
|
The fields output are the user's login name, the name of the terminal the
|
||||||
|
user is on, the host from which the user is logged in, the time the user
|
||||||
|
logged on, the time since the user last typed anything,
|
||||||
|
and the name and arguments of the current process.
|
||||||
|
.Pp
|
||||||
|
The options are as follows:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl h
|
||||||
|
Suppress the heading.
|
||||||
|
.It Fl i
|
||||||
|
Output is sorted by idle time.
|
||||||
|
.It Fl M
|
||||||
|
Extract values associated with the name list from the specified
|
||||||
|
core instead of the default
|
||||||
|
.Dq /dev/kmem .
|
||||||
|
.It Fl N
|
||||||
|
Extract the name list from the specified system instead of the
|
||||||
|
default
|
||||||
|
.Dq /netbsd .
|
||||||
|
.It Fl n
|
||||||
|
Show network addresses as numbers (normally
|
||||||
|
.Nm
|
||||||
|
interprets addresses and attempts to display them symbolically).
|
||||||
|
.It Fl w
|
||||||
|
Show wide output without truncating any fields.

The

|
command appeared in

.Bx 3.0 .
|
||||||
|
.Sh BUGS
|
||||||
|
The notion of the
|
||||||
|
.Dq current process
|
||||||
|
is muddy.
|
||||||
|
The current algorithm is ``the highest numbered process on the terminal
|
||||||
|
that is not ignoring interrupts, or, if there is none, the highest numbered
|
||||||
|
process on the terminal''.
|
||||||
|
This fails, for example, in critical sections of programs like the shell
|
||||||
|
and editor, or when faulty programs running in the background fork and fail
|
||||||
|
to ignore interrupts.
|
||||||
|
(In cases where no process can be found,
|
||||||
|
.Nm
|
||||||
|
prints
|
||||||
|
.Dq \- . )
|
||||||
|
.Pp
|
||||||
|
Background processes are not shown, even though they account for
|
||||||
|
much of the load on the system.
|
||||||
|
.Pp
|
||||||
|
Sometimes processes, typically those in the background, are printed with
|
||||||
|
null or garbaged arguments.
|
||||||
|
In these cases, the name of the command is printed in parentheses.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility does not know about the new conventions for detection of background
|
||||||
|
jobs.
|
||||||
|
It will sometimes find a background job instead of the right one.
