|
.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.
|
|
.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 f
|
|
Display file descriptor information for the process.
|
|
.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.
|
|
This feature requires
|
|
.Cd "options STACK"
|
|
or
|
|
.Cd "options DDB"
|
|
to be compiled into the kernel.
|
|
.It Fl s
|
|
Display security credential information for the process.
|
|
.It Fl t
|
|
Display thread information for the process.
|
|
.It Fl v
|
|
Display virtual memory mappings 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
|
|
Some information, such as VM and file descriptor information, is available
|
|
only to the owner of a process or the superuser.

.Sh BUGS
|
|
Some field values may include spaces, which limits the extent to which the
|
|
output of
|
|
.Nm
|
|
may be mechanically parsed.
|
|
.Pp
|
|
The display of open file or memory mapping pathnames is implemented using the
|
|
kernel's name cache.
|
|
It therefore does not work for file systems
|
|
that do not use the name cache, such as
|
|
.Xr devfs 4 ,
|
|
or if the name is not present in the cache due to removal.
|
|
.Pp
|
|
.Nm
|
|
currently supports extracting data only from a live kernel, and not from
|
|
kernel crash dumps.
