top: refactor man document so as to allow translations The majority of changes in this commit are intended to enable translation of top's man page. There were three kinds of errors as seen by that po4a-updatepo program. . a valid but unrecognized request concerning no-break . an internally defined macro with a groff .de request . occasional apostrophe at the beginning of some lines With respect to the apostrophe, some have been changed to back-tic since line placement could not be assured. And other parts were re-flowed to avoid temptations to escape as \' (technically an acute accent). Of course, the opening back-tic with closing apostrophe looks odd when ASCII, but should be rendered correctly as UTF-8. It may yet be necessary to change the remaining single 'opening' quotes to back-tics as translation proceeds. Should that become necessary, I intend to reduce quote usage to the bare minimum throughout the man document. There were also some formatting changes to enhance the man2html output and then to other formats via htmldoc. And, I wish to acknowledge that my meager groff skills do not serve those programs very well at all. In other words groff yet remains mostly incomprehensible to me. Lastly a few content plus copyright updates were made. Message(s): . Unknown macro '.c2 `'.

.\" ----------------------------------------------------------------------
\*(WE \*(CL
The traditional switches `\-' and whitespace are optional.
2002-07-25 03:55:34 +05:30
.\" ----------------------------------------------------------------------
.SH DESCRIPTION
.\" ----------------------------------------------------------------------
The \*(WE program provides a dynamic real-time view of a running system.
2011-03-31 16:45:12 +05:30
It can display\fB system\fR summary information as well as a list of
\*(TT currently being managed by the Linux kernel.
2002-07-25 03:55:34 +05:30
The types of system summary information shown and the types, order and
2011-03-31 16:45:12 +05:30
size of information displayed for processes are all user configurable
and that configuration can be made persistent across restarts.
2002-07-25 03:55:34 +05:30
2002-10-24 03:18:11 +05:30
The program provides a limited interactive interface for process
manipulation as well as a much more extensive interface for personal
2011-03-31 16:45:12 +05:30
configuration \*(Em encompassing every aspect of its operation.
And while \*(WE is referred to throughout this document, you are free
2002-07-25 03:55:34 +05:30
to name the program anything you wish.
That new name, possibly an alias, will then be reflected on \*(We's
2011-03-31 16:45:12 +05:30
display and used when reading and writing a \*(CF.

.SS Operation
.\" ----------------------------------------------------------------------
When operating \*(We, the two most important keys are the help (h or ?)
key and quit (`q') key.
Alternatively, you could simply use the traditional interrupt key (^C)
2002-10-24 03:18:11 +05:30
when you're done.
When started for the first time, you'll be presented with these traditional
elements on the main \*(We screen: 1) Summary Area; 2) Fields/Columns Header;
3) Task Area.
Each of these will be explored in the sections that follow.
There is also an Input/Message line between the Summary Area and Columns
Header which needs no further explanation.
The main \*(We screen is \fIgenerally\fR quite adaptive to changes in
terminal dimensions under X-Windows.
Other \*(We screens may be less so, especially those with static text.
It ultimately depends, however, on your particular window manager and
terminal emulator.
There may be occasions when their view of terminal size and current contents
differs from \*(We's view, which is always based on operating system calls.
Following any re-size operation, if a \*(We screen is corrupted, appears
incomplete or disordered, simply typing something innocuous like a
punctuation character or cursor motion key will usually restore it.
In extreme cases, the following sequence almost certainly will:
.nf
\fIkey/cmd objective \fR
^Z \fBsuspend\fR \*(We
fg \fBresume\fR \*(We
<Left> force a screen \fBredraw\fR (if necessary)
.fi
But if the display is still corrupted, there is one more step you could try.
Insert this command after \*(We has been suspended but before resuming it.
.nf
\fIkey/cmd objective \fR
reset restore your \fBterminal settings\fR
.fi
\*(NT the width of \*(We's display will be limited to \*(WX positions.
Displaying all fields requires \*(WF characters.
Remaining screen width is usually allocated to any variable width columns
currently visible.
The variable width columns, such as COMMAND, are noted in topic
3a. DESCRIPTIONS of Fields.
Actual output width may also be influenced by the \-w switch, which is
discussed in topic 1. COMMAND\-LINE Options.
Lastly, some of \*(We's screens or functions require the use of cursor
motion keys like the standard \*(KAs plus the Home, End, PgUp and PgDn keys.
2011-03-31 16:45:12 +05:30
If your terminal or emulator does not provide those keys, the following
combinations are accepted as alternatives:
.nf
\fI key equivalent-key-combinations \fR
Up alt +\fB \\\fR or alt +\fB k \fR
Down alt +\fB /\fR or alt +\fB j \fR
Left alt +\fB <\fR or alt +\fB h \fR
Right alt +\fB >\fR or alt +\fB l \fR(lower case L)
PgUp alt +\fB Up\fR or alt + ctrl +\fB k \fR
PgDn alt +\fB Down\fR or alt + ctrl +\fB j \fR
Home alt +\fB Left\fR or alt + ctrl +\fB h \fR
End alt +\fB Right\fR or alt + ctrl +\fB l \fR
.fi
2011-03-31 16:45:12 +05:30
The \fBUp\fR and \fBDown\fR \*(KAs have special significance when prompted
for line input terminated with the <Enter> key.
Those keys, or their aliases, can be used to retrieve previous input lines
which can then be edited and re-input.
And there are four additional keys available with line oriented input.
.nf
\fI key special-significance \fR
Up recall \fBolder\fR strings for re-editing
Down recall \fBnewer\fR strings or \fBerase\fR entire line
Insert toggle between \fBinsert\fR and \fBovertype\fR modes
Delete character \fBremoved\fR at cursor, moving others left
Home jump to \fBbeginning\fR of input line
End jump to \fBend\fR of input line

The following startup defaults assume no \*(CF, thus no user customizations.
2011-03-31 16:45:12 +05:30

2002-10-24 03:18:11 +05:30

.SS Linux Memory Types
.\" ----------------------------------------------------------------------
For our purposes there are three types of memory, and one is optional.
First is \*(MP, a limited resource where code and data must
reside when executed or referenced.
Next is the optional \*(MS, where modified (dirty) memory can be saved
and later retrieved if too many demands are made on \*(MP.
Lastly we have \*(MV, a nearly unlimited resource serving the
following goals:
.nf
1. abstraction, free from physical memory addresses/limits
2. isolation, every process in a separate address space
3. sharing, a single mapping can serve multiple needs
4. flexibility, assign a virtual address to a file
.fi
Regardless of which of these forms memory may take, all are managed as
pages (typically 4096 bytes) but expressed by default in \*(We as
KiB (kibibyte).
The memory discussed under topic `2c. MEMORY Usage' deals with \*(MP
and the \*(MS for the system as a whole.
The memory reviewed in topic `3. FIELDS / Columns Display'
embraces all three memory types, but for individual processes.
For each such process, every memory page is restricted to a single
quadrant from the table below.
Both \*(MP and \*(MV can include any of the four, while the \*(MS only
includes #1 through #3.
The memory in quadrant #4, when modified, acts as its own dedicated \*(MS.
.nf
\fBPrivate\fR | \fBShared\fR
\fB1\fR | \fB2\fR
\fBAnonymous\fR . stack |
. malloc() |
. brk()/sbrk() | . POSIX shm*
. mmap(PRIVATE, ANON) | . mmap(SHARED, ANON)
-----------------------+----------------------
. mmap(PRIVATE, fd) | . mmap(SHARED, fd)
\fBFile-backed\fR . pgms/shared libs |
\fB3\fR | \fB4\fR
.fi
The following may help in interpreting process level memory values displayed
as scalable columns and discussed under topic `3a. DESCRIPTIONS of Fields'.
.nf
%MEM \- simply RES divided by total \*(MP
CODE \- the `pgms' portion of quadrant \fB3\fR
DATA \- the entire quadrant \fB1\fR portion of VIRT plus all
explicit mmap file-backed pages of quadrant \fB3\fR
RES \- anything occupying \*(MP which, beginning with
Linux-4.5, is the sum of the following three fields:
RSan \- quadrant \fB1\fR pages, which include any
former quadrant \fB3\fR pages if modified
RSfd \- quadrant \fB3\fR and quadrant \fB4\fR pages
RSsh \- quadrant \fB2\fR pages
RSlk \- subset of RES which cannot be swapped out (any quadrant)
SHR \- subset of RES (excludes \fB1\fR, includes all \fB2\fR & \fB4\fR, some \fB3\fR)
SWAP \- potentially any quadrant except \fB4\fR
USED \- simply the sum of RES and SWAP
VIRT \- everything in-use and/or reserved (all quadrants)
.fi
\*(NT Even though program images and shared libraries are considered
\fIprivate\fR to a process, they will be accounted for as \fIshared\fR
(SHR) by the kernel.

\*(CL
2002-07-25 03:55:34 +05:30
The typically mandatory switch (`\-') and even whitespace are completely
2002-07-25 03:55:34 +05:30
optional.
.TP 5
\-\fBh\fR | \-\fBv\fR\ \ :\fIHelp/Version \fR
2011-03-31 16:45:12 +05:30
Show library version and the usage prompt, then quit.
.TP 5
\-\fBb\fR\ \ :\fIBatch-mode\fR operation \fR
Starts \*(We in Batch mode, which could be useful for sending output
from \*(We to other programs or to a file.
In this mode, \*(We will not accept input and runs until the iterations
limit you've set with the `\-n' \*(CO or until killed.
2002-07-25 03:55:34 +05:30
.TP 5
\-\fBc\fR\ \ :\fICommand-line/Program-name\fR toggle \fR
Starts \*(We with the last remembered `c' state reversed.
Thus, if \*(We was displaying command lines, now that field will show program
names, and vice versa.
\*(XC `c' \*(CI for additional information.

2002-07-25 03:55:34 +05:30
Specifies the delay between screen updates, and overrides the corresponding
value in one's personal \*(CF or the startup default.
Later this can be changed with the `d' or `s' \*(CIs.
2002-07-25 03:55:34 +05:30

top: provide the means to adjust scaled process memory This commit is an unrequested outgrowth of the earlier change dealing with summary area memory field scaling. That user selectable scaling provision is now extended to include 6 (at present) task oriented memory fields. The new companion 'e' (lower case) interactive command has been added and, like the 'E' command, it can cycle each of the currently displayed memory columns between KiB through TiB. There are, however, some differences. Where '+' indicates summary area truncation at a given radix, task memory fields are automatically scaled for their column. Thus, not all rows use the same scaling. And, while summary area field widths were not changed, the task memory columns were widened in order to offer more meaningful data when the radix was increased. The precision is automatically increased in step with each radix: MiB displays 2 decimal places, GiB 3 and TiB 4. To compliment that additional precision, both the %CPU and %MEM fields were widened by 1 column and now offer precision up to 3 decimal places. But, unique to %CPU, widening could already have occurred due to the number of processors in some massively parallel boxes. At any rate, total extra width for both memory and percentage fields could amount to twenty (precious) columns more. So for both the memory and % fields the original width (along with loss of precision) can be restored via new compiler conditionals which this commit also provides. p.s. and it will be rcfile preserved for any restarts!

top: refactor man document so as to allow translations The majority of changes in this commit are intended to enable translation of top's man page. There were three kinds of errors as seen by that po4a-updatepo program. . a valid but unrecognized request concerning no-break . an internally defined macro with a groff .de request . occasional apostrophe at the beginning of some lines With respect to the apostrophe, some have been changed to back-tic since line placement could not be assured. And other parts were re-flowed to avoid temptations to escape as \' (technically an acute accent). Of course, the opening back-tic with closing apostrophe looks odd when ASCII, but should be rendered correctly as UTF-8. It may yet be necessary to change the remaining single 'opening' quotes to back-tics as translation proceeds. Should that become necessary, I intend to reduce quote usage to the bare minimum throughout the man document. There were also some formatting changes to enhance the man2html output and then to other formats via htmldoc. And, I wish to acknowledge that my meager groff skills do not serve those programs very well at all. In other words groff yet remains mostly incomprehensible to me.

top: provide the means to adjust scaled process memory This commit is an unrequested outgrowth of the earlier change dealing with summary area memory field scaling. That user selectable scaling provision is now extended to include 6 (at present) task oriented memory fields. The new companion 'e' (lower case) interactive command has been added and, like the 'E' command, it can cycle each of the currently displayed memory columns between KiB through TiB. There are, however, some differences. Where '+' indicates summary area truncation at a given radix, task memory fields are automatically scaled for their column. Thus, not all rows use the same scaling. And, while summary area field widths were not changed, the task memory columns were widened in order to offer more meaningful data when the radix was increased. The precision is automatically increased in step with each radix: MiB displays 2 decimal places, GiB 3 and TiB 4. To compliment that additional precision, both the %CPU and %MEM fields were widened by 1 column and now offer precision up to 3 decimal places. But, unique to %CPU, widening could already have occurred due to the number of processors in some massively parallel boxes. At any rate, total extra width for both memory and percentage fields could amount to twenty (precious) columns more. So for both the memory and % fields the original width (along with loss of precision) can be restored via new compiler conditionals which this commit also provides. p.s. and it will be rcfile preserved for any restarts!

top: refactor man document so as to allow translations The majority of changes in this commit are intended to enable translation of top's man page. There were three kinds of errors as seen by that po4a-updatepo program. . a valid but unrecognized request concerning no-break . an internally defined macro with a groff .de request . occasional apostrophe at the beginning of some lines With respect to the apostrophe, some have been changed to back-tic since line placement could not be assured. And other parts were re-flowed to avoid temptations to escape as \' (technically an acute accent). Of course, the opening back-tic with closing apostrophe looks odd when ASCII, but should be rendered correctly as UTF-8. It may yet be necessary to change the remaining single 'opening' quotes to back-tics as translation proceeds. Should that become necessary, I intend to reduce quote usage to the bare minimum throughout the man document. There were also some formatting changes to enhance the man2html output and then to other formats via htmldoc. And, I wish to acknowledge that my meager groff skills do not serve those programs very well at all. In other words groff yet remains mostly incomprehensible to me. Lastly a few content plus copyright updates were made. Message(s): . Unknown macro '.c2 `'. Remove it from the document, or refer to the Locale::Po4a::Man manpage to see how po4a can handle new macros. . This page defines a new macro with '.de'. Since po4a is not a real groff parser, this is not supported. . Unknown macro ''real time' scheduling priority.'.

top: refactor man document so as to allow translations The majority of changes in this commit are intended to enable translation of top's man page. There were three kinds of errors as seen by that po4a-updatepo program. . a valid but unrecognized request concerning no-break . an internally defined macro with a groff .de request . occasional apostrophe at the beginning of some lines With respect to the apostrophe, some have been changed to back-tic since line placement could not be assured. And other parts were re-flowed to avoid temptations to escape as \' (technically an acute accent). Of course, the opening back-tic with closing apostrophe looks odd when ASCII, but should be rendered correctly as UTF-8. It may yet be necessary to change the remaining single 'opening' quotes to back-tics as translation proceeds. Should that become necessary, I intend to reduce quote usage to the bare minimum throughout the man document. There were also some formatting changes to enhance the man2html output and then to other formats via htmldoc. And, I wish to acknowledge that my meager groff skills do not serve those programs very well at all. In other words groff yet remains mostly incomprehensible to me. Lastly a few content plus copyright updates were made. Message(s): . Unknown macro '.c2 `'.

top: refactor man document so as to allow translations The majority of changes in this commit are intended to enable translation of top's man page. There were three kinds of errors as seen by that po4a-updatepo program. . a valid but unrecognized request concerning no-break . an internally defined macro with a groff .de request . occasional apostrophe at the beginning of some lines With respect to the apostrophe, some have been changed to back-tic since line placement could not be assured. And other parts were re-flowed to avoid temptations to escape as \' (technically an acute accent). Of course, the opening back-tic with closing apostrophe looks odd when ASCII, but should be rendered correctly as UTF-8. It may yet be necessary to change the remaining single 'opening' quotes to back-tics as translation proceeds. Should that become necessary, I intend to reduce quote usage to the bare minimum throughout the man document. There were also some formatting changes to enhance the man2html output and then to other formats via htmldoc.

The `=' equality operator requires only a partial match and that
can reduce your `if\-value' input requirements.
The `>' or `<' relational operators always employ string comparisons,
even with numeric fields.
They are designed to work with a field's default \fIjustification\fR and
with homogeneous data.
When some field's numeric amounts have been subjected to \fIscaling\fR
while others have not, that data is no longer homogeneous.

If you establish a relational filter and you \fBhave\fR changed the
default Numeric or Character \fIjustification\fR, that filter is likely to fail.
When a relational filter is applied to a memory field and you \fBhave not\fR
changed the \fIscaling\fR, it may produce misleading results.
This happens, for example, because `100.0m' (MiB) would appear greater
than `1.000g' (GiB) when compared as strings.
If your filtered results appear suspect, simply altering justification or
scaling may yet achieve the desired objective.
See the `j', `J' and `e' \*(CIs for additional information.

These examples illustrate how Other Filtering can be creatively
applied to achieve almost any desired result.
Single quotes are sometimes shown to delimit the spaces which are part of
a filter or to represent a request for status (^O) accurately.
But if you used them with if-values in real life, no matches would be found.
Assuming field \fBnTH\fR is displayed, the first filter will result in
only multi-threaded processes being shown.
It also reminds us that a trailing space is part of every displayed field.
The second filter achieves the exact same results with less typing.
.nf
!nTH=` 1 ' ( ' for clarity only )
nTH>1 ( same with less i/p )
.fi
With Forest View mode active and the \fBCOMMAND\fR column in view, this
filter effectively collapses child processes so that just 3 levels are shown.
.nf
!COMMAND=` `- ' ( ' for clarity only )
.fi
The final two filters appear as in response to the status request key (^O).
In reality, each filter would have required separate input.
The \fBPR\fR example shows the two concurrent filters necessary to display
tasks with priorities of 20 or more, since some might be negative.
Then by exploiting trailing spaces, the \fBnMin\fR series of filters could
achieve the failed `9999' objective discussed above.
.nf
`PR>20' + `!PR=-' ( 2 for right result )
`!nMin=0 ' + `!nMin=1 ' + `!nMin=2 ' + `!nMin=3 ' ...

.SS 6c. ADDING INSPECT Entries
.\" ----------------------------------------------------------------------
To exploit the `Y' \*(CI, you must add entries at the\fB end\fR of the
\*(We personal \*(CF.
Such entries simply reflect a file to be read or command/pipeline to be
executed whose results will then be displayed in a separate scrollable,
searchable window.
If you don't know the location or name of your \*(We rcfile, use the `W'
\*(CI to rewrite it and note those details.
Inspect entries can be added with a redirected echo or by editing the \*(CF.
Redirecting an echo risks overwriting the rcfile should it replace (>)
rather than append (>>) to that file.
Conversely, when using an editor care must be taken not to corrupt existing
lines, some of which will contain unprintable data or unusual characters.
Those Inspect entries beginning with a `#' character are ignored, regardless
of content.
Otherwise they consist of the following 3 elements, each of which\fI must\fR
be separated by a tab character (thus 2 `\\t' total):
.nf
.type: literal `file' or `pipe'
.name: selection shown on the Inspect screen
.fmts: string representing a path or command
.fi
The two types of Inspect entries are\fI not\fR interchangeable.
Those designated `\fBfile\fR' will be accessed using fopen and
must reference a single file in the `.fmts' element.
Entries specifying `\fBpipe\fR' will employ popen, their `.fmts' element
could contain many pipelined commands and, none can be interactive.
If the file or pipeline represented in your `.fmts' deals with the specific PID
input or accepted when prompted, then the format string must also contain
the `\fB%d\fR' specifier, as these examples illustrate.
.nf
.fmts= /proc/\fI%d\fR/numa_maps
.fmts= lsof -P -p\fI %d\fR
.fi
For `\fBpipe\fR' type entries only, you may also wish to redirect stderr to
stdout for a more comprehensive result.
Thus the format string becomes:
.nf
.fmts= pmap -x %d\fI 2>&1\fR
.fi
Here are examples of both types of Inspect entries as they might appear
in the rcfile.
The first entry will be ignored due to the initial `#' character.
For clarity, the pseudo tab depictions (^I) are surrounded by an
extra space but the actual tabs would not be.
.nf
# pipe ^I Sockets ^I lsof -n -P -i 2>&1
pipe ^I Open Files ^I lsof -P -p %d 2>&1
file ^I NUMA Info ^I /proc/%d/numa_maps
pipe ^I Log ^I tail -n100 /var/log/syslog | sort -Mr
.fi
Except for the commented entry above, these next examples show what could
be echoed to achieve similar results, assuming the rcfile name was `.toprc'.
However, due to the embedded tab characters, each of these lines should be
preceded by `\fB/bin/echo \-e\fR', not just a simple an `echo', to
enable backslash interpretation regardless of which shell you use.
.nf
"pipe\\tOpen Files\\tlsof -P -p %d 2>&1" >> ~/.toprc
"file\\tNUMA Info\\t/proc/%d/numa_maps" >> ~/.toprc
"pipe\\tLog\\ttail -n200 /var/log/syslog | sort -Mr" >> ~/.toprc
.fi
\fBCaution\fR:
If any inspect entry you create produces output with unprintable characters
they will be displayed in either the ^C notation or hexadecimal <FF> form,
depending on their value.
This applies to tab characters as well, which will show as `^I'.
If you want a truer representation, any embedded tabs should be expanded.
.nf
# next would have contained `\\t' ...
# file ^I <your_name> ^I /proc/%d/status
# but this will eliminate embedded `\\t' ...
pipe ^I <your_name> ^I cat /proc/%d/status | expand \-
.fi
The above example takes what could have been a `file' entry but employs
a `pipe' instead so as to expand the embedded tabs.
\*(NT While `\fBpipe\fR' type entries have been discussed in terms of pipelines
and commands, there is nothing to prevent you from including \fI shell scripts\fR
as well.
Perhaps even newly created scripts designed specifically for the `Y' \*(CI.
Lastly, as the number of your Inspect entries grows over time, the `Options:'
row will be truncated when screen width is exceeded.
That does not affect operation other than to make some selections invisible.
However, if some choices are lost to truncation but you want to see more options,
there is an easy solution hinted at below.
.nf
Inspection Pause at pid ...
Use: left/right then <Enter> ...
Options: help 1 2 3 4 5 6 7 8 9 10 11 ...
.fi
The entries in the \*(We rcfile would have a number for the `.name' element and
the `help' entry would identify a shell script you've written explaining what
those numbered selections actually mean.
In that way, many more choices can be made visible.

top: refactor man document so as to allow translations The majority of changes in this commit are intended to enable translation of top's man page. There were three kinds of errors as seen by that po4a-updatepo program. . a valid but unrecognized request concerning no-break . an internally defined macro with a groff .de request . occasional apostrophe at the beginning of some lines With respect to the apostrophe, some have been changed to back-tic since line placement could not be assured. And other parts were re-flowed to avoid temptations to escape as \' (technically an acute accent). Of course, the opening back-tic with closing apostrophe looks odd when ASCII, but should be rendered correctly as UTF-8. It may yet be necessary to change the remaining single 'opening' quotes to back-tics as translation proceeds. Should that become necessary, I intend to reduce quote usage to the bare minimum throughout the man document.

Start \*(We and make COMMAND the last (rightmost) column displayed.
If necessary, use the `c' \*(CT to display command lines and ensure
that forest view mode is active with the `V' \*(CT.
Then use the up/down arrow keys to position the display so that some
truncated command lines are shown (`+' in last position).
You may have to resize your xterm to produce truncation.
Lastly, use the `j' \*(CT to make the COMMAND column right justified.
Now use the right arrow key to reach the COMMAND column.
Continuing with the right arrow key, watch closely the direction
of travel for the command lines being shown.
.br
some lines travel left, while others travel right
eventually all lines will Switcheroo, and move right
