If standard output is an intelligent terminal (see below) then
|
|

as many processes as will fit on the terminal screen are displayed

by default. Otherwise, a good number of them are shown (around 20).

|
|
Raw cpu percentage is used to rank the processes. If
|
|
|
|
.I number
|
|
|

is given, then the top

.PP

.I Top
|
|
|
|
makes a distinction between terminals that support advanced capabilities
|
|
|
|
and those that do not. This
|
|
|
|
distinction affects the choice of defaults for certain options. In the
|
|
|
|
remainder of this document, an \*(lqintelligent\*(rq terminal is one that
|
|
|
|
supports cursor addressing, clear screen, and clear to end of line.
|
|
|
|
Conversely, a \*(lqdumb\*(rq terminal is one that does not support such
|
|
|
|
features. If the output of
|
|
|
|
.I top
|
|
|
|
is redirected to a file, it acts as if it were being run on a dumb
|
|
|
|
terminal.

.TP

2006-04-19 11:47:51 +00:00
|
|
|
.B \-C
|
|
|
|
Toggle CPU display mode.
|
|
|
|
By default top displays the weighted CPU percentage in the WCPU column
|
|
|
|
(this is the same value that
|
|
|
|
.IR ps (1)
|
|
|
|
displays as CPU).
|
|
|
|
Each time
|
|
|
|
.B \-C
|
|
|
|
flag is passed it toggles between \*(lqraw cpu\*(rq mode
|
|
|
|
and \*(lqweighted cpu\*(rq mode, showing the \*(lqCPU\*(rq or
|
|
|
|
the \*(lqWCPU\*(rq column respectively.
|
|
|
|
.TP
|
1997-03-23 18:51:21 +00:00
|
|
|
.B \-S
|
|
|
|
Show system processes in the display. Normally, system processes such as
|
|
|
|
the pager and the swapper are not shown. This option makes them visible.
|
|
|
|
.TP
|
2007-04-14 10:16:52 +00:00
|
|
|
.B \-a
|
|
|
|
Display command names derived from the argv[] vector, rather than real
|
|
|
|
executable name. It's useful when you want to watch applications, that
|
|
|
|
puts their status information there. If the real name differs from argv[0],
|
|
|
|
it will be displayed in parenthesis.
|
|
|
|
.TP
|
1997-03-23 18:51:21 +00:00
|
|
|
.B \-b
|
|
|
|
Use \*(lqbatch\*(rq mode. In this mode, all input from the terminal is
|
|
|
|
ignored. Interrupt characters (such as ^C and ^\e) still have an effect.
|
|
|
|
This is the default on a dumb terminal, or when the output is not a terminal.
|
|
|
|
.TP
|
2011-05-31 15:41:10 +00:00
|
|
|
.B \-H
|
|
|

Display each thread for a multithreaded process individually.
|
|
|
|
By default a single summary line is displayed for each process.

.TP
|
1997-03-23 18:51:21 +00:00
|
|
|
.B \-i
|
|
|
|
Use \*(lqinteractive\*(rq mode. In this mode, any input is immediately
|
|
|
|
read for processing. See the section on \*(lqInteractive Mode\*(rq
|
|
|
|
for an explanation of
|
|
|
|
which keys perform what functions. After the command is processed, the
|
|
|
|
screen will immediately be updated, even if the command was not
|
|
|
|
understood. This mode is the default when standard output is an
|
|
|
|
intelligent terminal.
|
|
|
|
.TP
|
|
|
|
.B \-I
|
|

Do not display idle processes.
|

By default, top displays both active and idle processes.

1997-03-23 18:51:21 +00:00
|

This option can only be used by root.
|
|
|
|
.TP
|
|
|
|
.B \-u
|
|
|
|
Do not take the time to map uid numbers to usernames. Normally,
|
|
|
|
.I top
|
|
|
|
will read as much of the file \*(lq/etc/passwd\*(rq as is necessary to map
|
|
|
|
all the user id numbers it encounters into login names. This option
|
|
|
|
disables all that, while possibly decreasing execution time. The uid
|
|
|
|
numbers are displayed instead of the names.

.TP

Write version number information to stderr then exit immediately.

No other processing takes place when this option is used. To see current

revision information while top is running, use the help command \*(lq?\*(rq.

wants to see before
|

.I top

.SH "INTERACTIVE MODE"
|
|
|
|
When
|
|
|
|

|

|
|
|
|
terminal and acts upon them accordingly. In this mode, the terminal is
|
|
|
|
put in \*(lqCBREAK\*(rq, so that a character will be
|
|
|
|
processed as soon as it is typed. Almost always, a key will be
|
|
|
|
pressed when
|
|
|
|
.I top
|
|
|
|
is between displays; that is, while it is waiting for
|
|
|
|
.I time
|
|
|
|
seconds to elapse. If this is the case, the command will be
|
|
|
|
processed and the display will be updated immediately thereafter
|
|
|
|
(reflecting any changes that the command may have specified). This
|
|
|
|
happens even if the command was incorrect. If a key is pressed while
|
|
|
|
.I top
|
|
|
|
is in the middle of updating the display, it will finish the update and
|
|
|
|
then process the command. Some commands require additional information,
|
|
|
|
and the user will be prompted accordingly. While typing this information
|
|
|
|
in, the user's erase and kill keys (as set up by the command
|
|
|
|
.IR stty )
|
|
|

are recognized, and a newline terminates the input.

.SH "THE DISPLAY"
|
|
|
|
The actual display varies depending on the specific variant of Unix
|
|
|
|
that the machine is running. This description may not exactly match
|
|
|
|
what is seen by top running on this particular machine. Differences
|
|
|
|
are listed at the end of this manual entry.
|
|
|
|
.PP
|
|
|
|
The top few lines of the display show general information
|
|
|
|
about the state of the system, including
|
|
|
|
the last process id assigned to a process (on most systems),
|
|
|
|
the three load averages,
|
|
|
|
the current time,
|
|
|
|
the number of existing processes,
|
|
|
|
the number of processes in each state
|
|
|
|
(sleeping, running, starting, zombies, and stopped),
|
|
|
|
and a percentage of time spent in each of the processor states
|
|
|
|
(user, nice, system, and idle).
|
1997-09-13 16:01:53 +00:00
|
|

It also includes information about physical and virtual memory allocation.
|
1997-03-23 18:51:21 +00:00

.PP
|
|
|
|
The remainder of the screen displays information about individual
|
|
|
|
processes. This display is similar in spirit to
|
|
|
|
.IR ps (1)
|
2007-04-17 03:12:39 +00:00
|
|
|
but it is not exactly the same. PID is the process id,
|
|
|
|
JID, when displayed, is the
|
|
|
|
.IR jail (8)
|
|
|
|
ID corresponding to the process,
|
|
|
|
USERNAME is the name of the process's owner (if
|
1997-03-23 18:51:21 +00:00
|
|
|
.B \-u
|
|
|
|
is specified, a UID column will be substituted for USERNAME),
|
|
|
|
PRI is the current priority of the process,
|
|
|
|
NICE is the nice amount (in the range \-20 to 20),
|
|
|
|
SIZE is the total size of the process (text, data, and stack),
|
2016-09-05 08:27:04 +00:00
|
|
|
RES is the current amount of resident memory,
|
|
|
|
SWAP is the approximate amount of swap, if enabled
|
|
|
|
(SIZE, RES and SWAP are given in kilobytes),
|
2006-05-16 15:27:43 +00:00
|
|
|
STATE is the current state (one of \*(lqSTART\*(rq, \*(lqRUN\*(rq
|
|
|
|
(shown as \*(lqCPUn\*(rq on SMP systems), \*(lqSLEEP\*(rq, \*(lqSTOP\*(rq,
|
|
|
|
\*(lqZOMB\*(rq, \*(lqWAIT\*(rq, \*(lqLOCK\*(rq or the event on which the
|
|
|
|
process waits),
|
|
|
|
C is the processor number on which the process is executing
|
|
|
|
(visible only on SMP systems),
|
1997-03-23 18:51:21 +00:00
|
|
|
TIME is the number of system and user cpu seconds that the process has used,
|
|
|
|
WCPU, when displayed, is the weighted cpu percentage (this is the same
|
|
|
|
value that
|
|
|
|
.IR ps (1)
|
|
|
|
displays as CPU),
|
|
|
|
CPU is the raw percentage and is the field that is sorted to determine
|
|
|
|
the order of the processes, and
|
|
|
|
COMMAND is the name of the command that the process is currently running
|
|
|
|
(if the process is swapped out, this column is marked \*(lq<swapped>\*(rq).
|
|
|
|
.SH NOTES
|
2011-05-31 15:41:10 +00:00
|
|
|
If a process is in the \*(lqSLEEP\*(rq or \*(lqLOCK\*(rq state,
|
|
|
|
the state column will report the name of the event or lock on which the
|
|
|
|
process is waiting.
|
|
|
|
Lock names are prefixed with an asterisk \*(lq*\*(rq while sleep events
|
|
|
|
are not.

.SH BUGS
|
|
|
|
Don't shoot me, but the default for
|
|
|
|
.B \-I
|
|
|
|
has changed once again. So many people were confused by the fact that
|
|
|
|
.I top
|
|
|
|
wasn't showing them all the processes that I have decided to make the
|
|
|
|
default behavior show idle processes, just like it did in version 2.
|
|
|
|
But to appease folks who can't stand that behavior, I have added the
|
|
|
|
ability to set \*(lqdefault\*(rq options in the environment variable
|
|
|
|
.B TOP
|
|
|
|
(see the OPTIONS section). Those who want the behavior that version
|
|
|
|
3.0 had need only set the environment variable
|
|
|
|
.B TOP
|
|
|
|
to \*(lq\-I\*(rq.
|
|
|
|
.PP
|
|
|
|
The command name for swapped processes should be tracked down, but this
|
|
|
|
would make the program run slower.
|
|
|
|
.PP
|
|
|
|
As with
|
|
|
|
.IR ps (1),
|
|
|
|
things can change while
|
|
|
|
.I top
|
|
|
|
is collecting information for an update. The picture it gives is only a
|
|
|
|
close approximation to reality.
