.Sh DESCRIPTION
|
|
.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
|
|
The
|
|
.Nm pargs ,
|
|
.Nm penv
|
|
and
|
|
.Nm pwdx
|
|
utilities display the arguments, environment, and current working directory,
|
|
respectively of the process specified by
|
|
.Ar pid
|
|
argument.
|
|
They mimic the behavior of Solaris utilities of the same names.
|
|
.Pp
|
|
If the
|
|
.Fl -libxo
|
|
flag is specified the output is generated 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.
|

|
|
The following commands are available for
|
|

|
|
Display file descriptor information for the process.
|
|
.Pp

|
|
.Fl C
|
|
subcommand flag is used then additional capability information is printed.
|
|
.It Ar signal(s) | Fl i
|
|
Display signal pending and disposition information for the process.
|
|
.Pp
|
|
If the
|
|
.Fl n

|
subcommand option is used, the signal numbers are shown instead of signal
|
|
names.
|
|
.Pp
|
|
Substring commands are accepted.
|
|
.It Ar tsignal(s) | Fl j
|
|
Display signal pending and blocked information for the process's threads.
|
|
.Pp
|
|
If the
|
|
.Fl n

subcommand option is used, the signal numbers are shown instead of signal
|
|
names.
|
|
.Pp
|
|
Substring commands are accepted.
|
|
.It Ar kstack | 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.
|
|
.Pp
|
|
If the
|
|
.Fl v
|
|
subcommand option is used (or the command flag is repeated), function
|
|
offsets as well as function names are printed.
|
|
.It Ar rlimit | Fl l
|
|

|
.Pp
|
|
If the
|
|

|
.Pq or Fl H
|
|
subcommand flag
|
|
is used then per-thread statistics are printed, rather than per-process
|
|

|
|
information corresponds.
|
|

.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
|
|
Information for VM, file descriptor, and cpuset options is available

|
|
The display of open file or memory mapping pathnames is implemented using the
|
|
kernel's name cache.
|
|
If a file system does not use the name cache, or the path to a file is not in
|
|
the cache, a path will not be displayed.

currently supports extracting data only from a live kernel, and not from

kernel crash dumps.
