.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility
|
|
displays a header line, followed by lines containing information about
|
|
all of your
|
|
processes that have controlling terminals.
|
|
If the
|
|
.Fl x
|
|
options is specified,
|
|
.Nm
|
|
will also display processes that do not have controlling terminals.
|
|
.Pp
|
|
A different set of processes can be selected for display by using any
|
|
combination of the
|
|
.Fl a , G , J , p , T , t ,
|
|
and
|
|
.Fl U
|
|
options.
|
|
If more than one of these options are given, then
|
|
.Nm
|
|
will select all processes which are matched by at least one of the
|
|
given options.
|
|
.Pp
|
|
For the processes which have been selected for display,
|
|
.Nm
|
|
will usually display one line per process.
|
|
The
|
|
.Fl H
|
|
option may result in multiple output lines (one line per thread) for
|
|
some processes.
|
|
By default all of these output lines are sorted first by controlling
|
|
terminal, then by process ID.
|
|
The
|
|
.Fl m , r , u ,
|
|
and
|
|
.Fl v
|
|
options will change the sort order.
|
|
If more than one sorting option was given, then the selected processes
|
|
will be sorted by the last sorting option which was specified.
|
|
.Pp
|
|
For the processes which have been selected for display, the information
|
|
to display is selected based on a set of keywords (see the
|
|
.Fl L , O ,
|
|
and
|
|
.Fl o
|
|
options).
|
|
The default output format includes, for each process, the process' ID,
|
|
controlling terminal, state, CPU time (including both user and system time)
|
|
and associated command.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl -libxo
|
|
Generate output via
|
|
.Xr libxo 3
|
|
in a selection of different human and machine readable formats.
|
|
See
|
|
.Xr xo_parse_args 3
|
|
for details on command line arguments.
|
|
.It Fl a
|
|
Display information about other users' processes as well as your own.
|
|
If the
|
|
.Va security.bsd.see_other_uids
|
|
sysctl is set to zero, this option is honored only if the UID of the user is 0.
|
|
.It Fl c
|
|
Change the
|
|
.Dq command
|
|
column output to just contain the executable name,
|
|
rather than the full command line.
|
|
.It Fl C
|
|
Change the way the CPU percentage is calculated by using a
|
|
.Dq raw
|
|
CPU calculation that ignores
|
|
.Dq resident
|
|
time (this normally has
|
|
no effect).
|
|
.It Fl d
|
|
Arrange processes into descendancy order and prefix each command with
|
|
indentation text showing sibling and parent/child relationships.
|
|
If either of the
|
|
.Fl m
|
|
and
|
|
.Fl r
|
|
options are also used, they control how sibling processes are sorted
|
|
relative to each other.
|
|
Note that this option has no effect if the
|
|
.Dq command
|
|
column is not the last column displayed.
|
|
.It Fl e
|
|
Display the environment as well.
|
|
.It Fl f
|
|
Show command-line and environment information about swapped out processes.
|
|
This option is honored only if the UID of the user is 0.
|
|
.It Fl G
|
|
Display information about processes which are running with the specified
|
|
real group IDs.
|
|
.It Fl H
|
|
Show all of the
|
|
.Em kernel visible
|
|
threads associated with each process.
|
|
Depending on the threading package that
|
|
is in use, this may show only the process, only the kernel scheduled entities,
|
|
or all of the process threads.
|
|
.It Fl h
|
|
Repeat the information header as often as necessary to guarantee one
|
|
header per page of information.
|
|
.It Fl j
|
|
Print information associated with the following keywords:
|
|
.Cm user , pid , ppid , pgid , sid , jobc , state , tt , time ,
|
|
and
|
|
.Cm command .
|
|
.It Fl J
|
|
Display information about processes which match the specified jail IDs.
|
|
This may be either the
|
|
.Cm jid
|
|
or
|
|
.Cm name
|
|
of the jail.
|
|
Use
|
|
.Fl J
|
|
.Sy 0
|
|
to display only host processes.
|
|
This flag implies
|
|
.Fl x
|
|
by default.
|
|
.It Fl L
|
|
List the set of keywords available for the
|
|
.Fl O
|
|
and
|
|
.Fl o
|
|
options.
|
|
.It Fl l
|
|
Display information associated with the following keywords:
|
|
.Cm uid , pid , ppid , cpu , pri , nice , vsz , rss , mwchan , state ,
|
|
.Cm tt , time ,
|
|
and
|
|
.Cm command .
|
|
.It Fl M
|
|
Extract values associated with the name list from the specified core
|
|
instead of the currently running system.
|
|
.It Fl m
|
|
Sort by memory usage, instead of the combination of controlling
|
|
terminal and process ID.
|
|
.It Fl N
|
|
Extract the name list from the specified system instead of the default,
|
|
which is the kernel image the system has booted from.
|
|
.It Fl O
|
|
Add the information associated with the space or comma separated list
|
|
of keywords specified, after the process ID,
|
|
in the default information
|
|
display.
|
|
Keywords may be appended with an equals
|
|
.Pq Ql =
|
|
sign and a string.
|
|
This causes the printed header to use the specified string instead of
|
|
the standard header.
|
|
.It Fl o
|
|
Display information associated with the space or comma separated
|
|
list of keywords specified.
|
|
The last keyword in the list may be appended with an equals
|
|
.Pq Ql =
|
|
sign and a string that spans the rest of the argument, and can contain
|
|
space and comma characters.
|
|
This causes the printed header to use the specified string instead of
|
|
the standard header.
|
|
Multiple keywords may also be given in the form of more than one
|
|
.Fl o
|
|
option.
|
|
So the header texts for multiple keywords can be changed.
|
|
If all keywords have empty header texts, no header line is written.
|
|
.It Fl p
|
|
Display information about processes which match the specified process IDs.
|
|
.It Fl r
|
|
Sort by current CPU usage, instead of the combination of controlling
|
|
terminal and process ID.
|
|
.It Fl S
|
|
Change the way the process times, namely cputime, systime, and usertime,
|
|
are calculated by summing all exited children to their parent process.
|
|
.It Fl T
|
|
Display information about processes attached to the device associated
|
|
with the standard input.
|
|
.It Fl t
|
|
Display information about processes attached to the specified terminal
|
|
devices.
|
|
Full pathnames, as well as abbreviations (see explanation of the
|
|
.Cm tt
|
|
keyword) can be specified.
|
|
.It Fl U
|
|
Display the processes belonging to the specified usernames.
|
|
.It Fl u
|
|
Display information associated with the following keywords:
|
|
.Cm user , pid , %cpu , %mem , vsz , rss , tt , state , start , time ,
|
|
and
|
|
.Cm command .
|
|
The
|
|
.Fl u
|
|
option implies the
|
|
.Fl r
|
|
option.
|
|
.It Fl v
|
|
Display information associated with the following keywords:
|
|
.Cm pid , state , time , sl , re , pagein , vsz , rss , lim , tsiz ,
|
|
.Cm %cpu , %mem ,
|
|
and
|
|
.Cm command .
|
|
The
|
|
.Fl v
|
|
option implies the
|
|
.Fl m
|
|
option.
|
|
.It Fl w
|
|
Use 132 columns to display information, instead of the default which
|
|
is your window size.
|
|
If the
|
|
.Fl w
|
|
option is specified more than once,
|
|
.Nm
|
|
will use as many columns as necessary without regard for your window size.
|
|
Note that this option has no effect if the
|
|
.Dq command
|
|
column is not the last column displayed.
|
|
.It Fl X
|
|
When displaying processes matched by other options, skip any processes
|
|
which do not have a controlling terminal.
|
|
This is the default behaviour.
|
|
.It Fl x
|
|
When displaying processes matched by other options, include processes
|
|
which do not have a controlling terminal.
|
|
This is the opposite of the
|
|
.Fl X
|
|
option.
|
|
If both
|
|
.Fl X
|
|
and
|
|
.Fl x
|
|
are specified in the same command, then
|
|
.Nm
|
|
will use the one which was specified last.
|
|
.It Fl Z
|
|
Add
|
|
.Xr mac 4
|
|
label to the list of keywords for which
|
|
.Nm
|
|
will display information.
|
|
.El
|
|
.Pp
|
|
A complete list of the available keywords are listed below.
|
|
Some of these keywords are further specified as follows:
|
|
.Bl -tag -width lockname
|
|
.It Cm %cpu
|
|
The CPU utilization of the process; this is a decaying average over up to
|
|
a minute of previous (real) time.
|
|
Since the time base over which this is computed varies (since processes may
|
|
be very young) it is possible for the sum of all
|
|
.Cm %cpu
|
|
fields to exceed 100%.
|
|
.It Cm %mem
|
|
The percentage of real memory used by this process.

|
The event (an address in the system) on which a process waits.
|
|
When printed numerically, the initial part of the address is
|
|
trimmed off and the result is printed in hex, for example, 0x80324000 prints
|
|
as 324000.
|
|
.El
|
|
.Pp
|
|
When printing using the command keyword, a process that has exited and
|
|
has a parent that has not yet waited for the process (in other words, a zombie)
|
|
is listed as
|
|
.Dq Li <defunct> ,
|
|
and a process which is blocked while trying
|
|
to exit is listed as
|
|
.Dq Li <exiting> .
|
|
If the arguments cannot be located (usually because it has not been set, as is
|
|
the case of system processes and/or kernel threads) the command name is printed
|
|
within square brackets.
|
|
The
|
|
.Nm
|
|
utility first tries to obtain the arguments cached by the kernel (if they were
|
|
shorter than the value of the
|
|
.Va kern.ps_arg_cache_limit
|
|
sysctl).
|
|
The process can change the arguments shown with
|
|
.Xr setproctitle 3 .
|
|
Otherwise,
|
|
.Nm
|
|
makes an educated guess as to the file name and arguments given when the
|
|
process was created by examining memory or the swap area.
|
|
The method is inherently somewhat unreliable and in any event a process
|
|
is entitled to destroy this information.
|
|
The ucomm (accounting) keyword can, however, be depended on.
|
|
If the arguments are unavailable or do not agree with the ucomm keyword,
|
|
the value for the ucomm keyword is appended to the arguments in parentheses.

.Sh ENVIRONMENT
|
|
The following environment variables affect the execution of
|
|
.Nm :
|
|
.Bl -tag -width ".Ev COLUMNS"
|
|
.It Ev COLUMNS
|
|
If set, specifies the user's preferred output width in column positions.
|
|
By default,
|
|
.Nm
|
|
attempts to automatically determine the terminal width.
|
|
.El
|
|
.Sh FILES
|
|
.Bl -tag -width ".Pa /boot/kernel/kernel" -compact
|
|
.It Pa /boot/kernel/kernel

.Sh STANDARDS
|
|
For historical reasons, the
|
|
.Nm
|
|
utility under
|
|
.Fx
|
|
supports a different set of options from what is described by
|
|
.St -p1003.2 ,
|
|
and what is supported on
|
|
.No non- Ns Bx
|
|
operating systems.
|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command appeared in
|
|
.At v3
|
|
in section 8 of the manual.
|
|
.Sh BUGS
|
|
Since
|
|
.Nm
|
|
cannot run faster than the system and is run as any other scheduled
|
|
process, the information it displays can never be exact.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility does not correctly display argument lists containing multibyte
|
|
characters.
