43 utility displays detailed information about the processes identified by the
47 flag is used, all processes.
48 It can also display information extracted from a process core file, if
49 the core file is specified as the argument.
51 By default, basic process statistics are printed; one of the following
52 options may be specified in order to select more detailed process information
54 .Bl -tag -width indent
56 Display binary information for the process.
58 Display command line arguments for the process.
60 Display environment variables for the process.
62 Display file descriptor information for the process.
64 Display signal pending and disposition information for the process.
66 Display signal pending and blocked information for the process's threads.
68 Display the stacks of kernel threads in the process, excluding stacks of
69 threads currently running on a CPU and threads with stacks swapped to disk.
70 If the flag is repeated, function offsets as well as function names are
73 Display resource limits for the process.
75 Display resource usage information for the process.
77 Display security credential information for the process.
79 Display thread information for the process.
81 Display virtual memory mappings for the process.
83 Display ELF auxiliary vector for the process.
86 All options generate output in the format of a table, the first field of
87 which is the process ID to which the row of information corresponds.
90 flag may be used to suppress table headers.
94 flag may be used to specify a wait interval at which to repeat the printing
95 of the requested process information.
98 flag is not specified, the output will not repeat.
102 flag requests the printing of additional capability information in the file
107 flag may be used to request per-thread statistics rather than per-process
108 statistics for some options.
109 For those options, the second field in the table will list the thread ID
110 to which the row of information corresponds.
112 Some information, such as VM and file descriptor information, is available
113 only to the owner of a process or the superuser.
114 .Ss Binary Information
115 Display the process ID, command, and path to the process binary:
117 .Bl -tag -width indent -compact
123 osreldate for process binary
125 path to process binary (if available)
127 .Ss Command Line Arguments
128 Display the process ID, command, and command line arguments:
130 .Bl -tag -width indent -compact
136 command line arguments (if available)
139 Display detailed information about each file descriptor referenced by a
140 process, including the process ID, command, file descriptor number, and
141 per-file descriptor object information, such as object type and file system
143 By default, the following information will be printed:
145 .Bl -tag -width indent -compact
151 file descriptor number or cwd/root/jail
157 file descriptor flags
159 file descriptor reference count
161 file descriptor offset
165 file path or socket addresses (if available)
168 The following file descriptor types may be displayed:
170 .Bl -tag -width X -compact
188 pseudo-terminal master
193 The following vnode types may be displayed:
195 .Bl -tag -width X -compact
216 The following file descriptor flags may be displayed:
218 .Bl -tag -width X -compact
236 descriptor is a capability
241 flag is specified, the vnode type, reference count, and offset fields will be
242 omitted, and a new capabilities field will be included listing capabilities,
245 present for each capability descriptor.
246 .Ss Signal Disposition Information
247 Display signal pending and disposition for a process:
249 .Bl -tag -width ident -compact
257 process signal disposition details, three symbols
258 .Bl -tag -width X -compact
260 if signal is pending in the global process queue, - otherwise
262 if signal delivery disposition is SIGIGN, - otherwise
264 if signal delivery is to catch it, - otherwise
270 switch is given, the signal numbers are shown instead of signal names.
271 .Ss Thread Signal Information
272 Display signal pending and blocked for a process's threads:
274 .Bl -tag -width ident -compact
284 thread signal delivery status, two symbols
285 .Bl -tag -width X -compact
287 if signal is pending for the thread, - otherwise
289 if signal is blocked in the thread signal mask, - if not blocked
295 switch has the same effect as for the
297 switch: the signal numbers are shown instead of signal names.
298 .Ss Kernel Thread Stacks
299 Display kernel thread stacks for a process, allowing further interpretation
300 of thread wait channels.
303 flag is repeated, function offsets, not just function names, are printed.
305 This feature requires
309 to be compiled into the kernel.
311 .Bl -tag -width indent -compact
321 kernel thread call stack
323 .Ss Security Credentials
324 Display process credential information:
326 .Bl -tag -width indent -compact
344 file creation mode mask
351 The following credential flags may be displayed:
353 .Bl -tag -width X -compact
357 .Ss Thread Information
358 Display per-thread information, including process ID, per-thread ID, name,
359 CPU, and execution state:
361 .Bl -tag -width indent -compact
371 current or most recent CPU run on

449 one or more superpage mappings are used
451 grows down (top-down stack)
453 grows up (bottom-up stack)

468 Some field values may include spaces, which limits the extent to which the
471 may be mechanically parsed.
473 The display of open file or memory mapping pathnames is implemented using the
475 If a file system does not use the name cache, or the path to a file is not in
476 the cache, a path will not be displayed.
479 currently supports extracting data only from a live kernel, and not from
