|
||||
.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.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.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
|
||||
.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
|
||||
.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
|
||||
.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
|
||||
.B \-H
|
||||
Display each thread for a multithreaded process individually.
|
||||
By default a single summary line is displayed for each process.
|
||||
.TP
|
||||
.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.
|
||||
.TP
|
||||
.B \-j
|
||||
Display the
|
||||
.IR jail (8)
|
||||
ID.
|
||||
.TP
|
||||
.B \-t
|
||||
Do not display the
|
||||
.I top
|
||||
process.
|
||||
.TP
|
||||
.BI \-m display
|
||||
Display either 'cpu' or 'io' statistics. Default is 'cpu'.
|
||||
.TP
|
||||
.B \-n
|
||||
Use \*(lqnon-interactive\*(rq mode. This is identical to \*(lqbatch\*(rq
|
||||
mode.
|
||||
.TP
|
||||
.B \-P
|
||||
Display per-cpu CPU usage statistics.
|
||||
.TP
|
||||
.B \-q
|
||||
Renice
|
||||
.I top
|
||||
to -20 so that it will run faster. This can be used when the system is
|
||||
being very sluggish to improve the possibility of discovering the problem.
|
||||
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
|
||||
.B \-v
|
||||
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.
|
||||
.TP
|
||||
.B \-w
|
||||
Display approximate swap usage for each process.
|
||||
.TP
|
||||
.B \-z
|
||||
Do not display the system idle process.
|
||||
.TP
|
||||
.BI \-d count
|
||||
Show only
|
||||
.I count
|
||||
displays, then exit. A display is considered to be one update of the
|
||||
screen. This option allows the user to select the number of displays he
|
||||
wants to see before
|
||||
.I top
|
||||
automatically exits. For intelligent terminals, no upper limit
|
||||
is set. The default is 1 for dumb terminals.
|
||||
.TP
|
||||
.BI \-s time
|
||||
Set the delay between screen updates to
|
||||
.I time
|
||||
seconds. The default delay between updates is \nD seconds.
|
||||
.TP
|
||||
.BI \-o field
|
||||
Sort the process display area on the specified field. The field name
|
||||
is the name of the column as seen in the output, but in lower case:
|
||||
\*(lqcpu\*(lq, \*(rqsize\*(lq, \*(rqres\*(lq, \*(rqtime\*(lq,
|
||||
\*(rqpri\*(lq, \*(rqthreads\*(lq, \*(lqtotal\*(lq, \*(rqread\*(lq,
|
||||
\*(rqwrite\*(lq, \*(rqfault\*(lq, \*(rqvcsw\*(lq, \*(rqivcsw\*(lq,
|
||||
\*(lqjid\*(lq, \*(rqswap\*(lq or \*(rqpid\*(lq.
|
||||
.TP
|
||||
.BI \-J jail
|
||||
Show only those processes owned by
|
||||
.IR jail .
|
||||
This may be either the
|
||||
.B jid
|
||||
or
|
||||
.B name
|
||||
of the jail.
|
||||
Use
|
||||
.B 0
|
||||
to limit to host processes.
|
||||
Using this option implies the
|
||||
.B \-j
|
||||
flag.
|
||||
.PP
|
||||
.BI \-U username
|
||||
Show only those processes owned by
|
||||
.IR username .
|
||||
This option currently only accepts usernames and will not understand
|
||||
uid numbers.
|
||||
.PP
|
||||
Both
|
||||
.I count
|
||||
and
|
||||
.I number
|
||||
fields can be specified as \*(lqinfinite\*(rq, indicating that they can
|
||||
stretch as far as possible. This is accomplished by using any proper
|
||||
prefix of the keywords
|
||||
\*(lqinfinity\*(rq,
|
||||
\*(lqmaximum\*(rq,
|
||||
or
|
||||
\*(lqall\*(rq.
|
||||
The default for
|
||||
.I count
|
||||
on an intelligent terminal is, in fact,
|
||||
.BI infinity .
|
||||
.PP
|
||||
The environment variable
|
||||
.B TOP
|
||||
is examined for options before the command line is scanned. This enables
|
||||
a user to set his or her own defaults. The number of processes to display
|
||||
can also be specified in the environment variable
|
||||
.BR TOP .
|
||||
The options
|
||||
.BR \-a ,
|
||||
.BR \-C ,
|
||||
.BR \-H ,
|
||||
.BR \-I ,
|
||||
.BR \-j ,
|
||||
.BR \-P ,
|
||||
.BR \-S ,
|
||||
.BR \-t ,
|
||||
.BR \-u ,
|
||||
.BR \-w ,
|
||||
and
|
||||
.B \-z
|
||||
are actually toggles. A second specification of any of these options
|
||||
will negate the first. Thus a user who has the environment variable
|
||||
.B TOP
|
||||
set to \*(lq\-I\*(rq may use the command \*(lqtop \-I\*(rq to see idle processes.
|
||||
.SH "INTERACTIVE MODE"
|
||||
When
|
||||
.I top
|
||||
is running in \*(lqinteractive mode\*(rq, it reads commands from the
|
||||
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.
|
||||
.PP
|
||||
These commands are currently recognized (^L refers to control-L):
|
||||
.TP
|
||||
.B ^L
|
||||
Redraw the screen.
|
||||
.IP "\fBh\fP\ or\ \fB?\fP"
|
||||
Display a summary of the commands (help screen). Version information
|
||||
is included in this display.
|
||||
.TP
|
||||
.B q
|
||||
Quit
|
||||
.IR top.
|
||||
.TP
|
||||
.B d
|
||||
Change the number of displays to show (prompt for new number).
|
||||
Remember that the next display counts as one, so typing
|
||||
.B d1
|
||||
will make
|
||||
.I top
|
||||
show one final display and then immediately exit.
|
||||
.TP
|
||||
.B m
|
||||
Toggle the display between 'cpu' and 'io' modes.
|
||||
.TP
|
||||
.B n or #
|
||||
Change the number of processes to display (prompt for new number).
|
||||
.TP
|
||||
.B s
|
||||
Change the number of seconds to delay between displays
|
||||
(prompt for new number).
|
||||
.TP
|
||||
.B S
|
||||
Toggle the display of system processes.
|
||||
.TP
|
||||
.B a
|
||||
Toggle the display of process titles.
|
||||
.TP
|
||||
.B k
|
||||
Send a signal (\*(lqkill\*(rq by default) to a list of processes. This
|
||||
acts similarly to the command
|
||||
.IR kill (1)).
|
||||
.TP
|
||||
.B r
|
||||
Change the priority (the \*(lqnice\*(rq) of a list of processes.
|
||||
This acts similarly to the command
|
||||
.IR renice (8)).
|
||||
.TP
|
||||
.B u
|
||||
Display only processes owned by a specific set of usernames (prompt for
|
||||
username). If the username specified is simply \*(lq+\*(rq or \*(lq-\*(rq,
|
||||
then processes belonging to all users will be displayed. Usernames can be added
|
||||
to and removed from the set by prepending them with \*(lq+\*(rq and
|
||||
\*(lq-\*(rq, respectively.
|
||||
.TP
|
||||
.B o
|
||||
Change the order in which the display is sorted. This command is not
|
||||
available on all systems. The sort key names vary from system to system
|
||||
but usually include: \*(lqcpu\*(rq, \*(lqres\*(rq, \*(lqsize\*(rq,
|
||||
\*(lqtime\*(rq. The default is cpu.
|
||||
.TP
|
||||
.B e
|
||||
Display a list of system errors (if any) generated by the last
|
||||
.BR k ill
|
||||
or
|
||||
.BR r enice
|
||||
command.
|
||||
.TP
|
||||
.B H
|
||||
Toggle the display of threads.
|
||||
.TP
|
||||
.B i
|
||||

|
||||
.BR I )
|
||||
Toggle the display of idle processes.
|
||||
.TP
|
||||
.B j
|
||||
Toggle the display of
|
||||
.IR jail (8)
|
||||
ID.
|
||||
.TP
|
||||
.B J
|
||||
Display only processes owned by a specific jail (prompt for jail).
|
||||
If the jail specified is simply \*(lq+\*(rq, then processes belonging
|
||||
to all jails and the host will be displayed.
|
||||
This will also enable the display of JID.
|
||||
.TP
|
||||
.B P
|
||||
Toggle the display of per-CPU statistics.
|
||||
.TP
|
||||

.I top
|
||||
process.
|

.B w
|
||||
Toggle the display of swap usage.
|
||||
.TP
|
||||
.B z
|

Toggle the display of the system idle process.
|
||||
.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).
|
||||
It also includes information about physical and virtual memory allocation.
|
||||
.PP
|
||||
The remainder of the screen displays information about individual
|
||||
processes. This display is similar in spirit to
|
||||
.IR ps (1)
|
||||
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
|
||||
.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),
|
||||
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),
|
||||
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),
|
||||
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
|
||||
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.
