.Sh SYNOPSIS
|
|
.Nm

|
.Op Fl b | c | e | f | i | j | k | l | r | s | S | t | v | x

.Op Fl a | Ar pid | Ar core ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility displays detailed information about the processes identified by the
|
|
.Ar pid
|
|
arguments, or if the
|
|
.Fl a
|
|
flag is used, all processes.
|
|
It can also display information extracted from a process core file, if
|
|
the core file is specified as the argument.
|
|
.Pp
|
|
By default, basic process statistics are printed; one of the following
|
|
options may be specified in order to select more detailed process information
|
|
for printing:
|
|
.Bl -tag -width indent
|
|
.It Fl b
|
|
Display binary information for the process.
|
|
.It Fl c
|
|
Display command line arguments for the process.
|
|
.It Fl e
|
|
Display environment variables for the process.
|
|
.It Fl f
|
|
Display file descriptor information for the process.
|
|
.It Fl i
|
|
Display signal pending and disposition information for the process.
|
|
.It Fl j
|
|
Display signal pending and blocked information for the process's threads.
|
|
.It Fl k
|
|
Display the stacks of kernel threads in the process, excluding stacks of
|
|
threads currently running on a CPU and threads with stacks swapped to disk.
|
|
If the flag is repeated, function offsets as well as function names are
|
|
printed.
|
|
.It Fl l
|
|
Display resource limits for the process.
|
|
.It Fl r
|
|
Display resource usage information for the process.
|
|
.It Fl s
|
|
Display security credential information for the process.
|
|
.It Fl S
|
|
Display the cpuset information for the thread.
|
|
.It Fl t
|
|
Display thread information for the process.
|
|
.It Fl v
|
|
Display virtual memory mappings for the process.
|
|
.It Fl x
|
|
Display ELF auxiliary vector for the process.
|
|
.El
|
|
.Pp
|
|
All options generate output in the format of a table, the first field of
|
|
which is the process ID to which the row of information corresponds.
|
|
The
|
|
.Fl h
|
|
flag may be used to suppress table headers.
|
|
.Pp
|
|
The
|
|
.Fl w
|
|
flag may be used to specify a wait interval at which to repeat the printing
|
|
of the requested process information.
|
|
If the
|
|
.Fl w
|
|
flag is not specified, the output will not repeat.
|
|
.Pp
|
|
The
|
|
.Fl C
|
|
flag requests the printing of additional capability information in the file
|
|
descriptor view.
|
|
.Pp
|
|
The
|
|
.Fl H
|
|
flag may be used to request per-thread statistics rather than per-process
|
|
statistics for some options.
|
|
For those options, the second field in the table will list the thread ID
|
|
to which the row of information corresponds.
|
|
The
|
|
.Fl H
|
|
flag is implied for the
|
|
.Fl S
|
|
mode.
|
|
.Pp
|
|
Information for VM, file descriptor, and cpuset options is available
|
|
only to the owner of a process or the superuser.
|
|
A cpuset value displayed as -1 means that the information is either invalid
|
|
or not available.
|
|
