33 .Nd get detailed process information
40 .Op Fl b | c | e | f | i | j | k | l | s | t | v | x
45 utility displays detailed information about the processes identified by the
49 flag is used, all processes.
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 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 security credential information for the process.
77 Display thread information for the process.
79 Display virtual memory mappings for the process.
81 Display ELF auxiliary vector for the process.
84 All options generate output in the format of a table, the first field of
85 which is the process ID to which the row of information corresponds.
88 flag may be used to suppress table headers.
92 flag may be used to specify a wait interval at which to repeat the printing
93 of the requested process information.
96 flag is not specified, the output will not repeat.
100 flag requests the printing of additional capability information in the file
103 Some information, such as VM and file descriptor information, is available
104 only to the owner of a process or the superuser.
105 .Ss Binary Information
106 Display the process ID, command, and path to the process binary:
108 .Bl -tag -width indent -compact
114 osreldate for process binary
116 path to process binary (if available)
118 .Ss Command Line Arguments
119 Display the process ID, command, and command line arguments:
121 .Bl -tag -width indent -compact
127 command line arguments (if available)
130 Display detailed information about each file descriptor referenced by a
131 process, including the process ID, command, file descriptor number, and
132 per-file descriptor object information, such as object type and file system
134 By default, the following information will be printed:
136 .Bl -tag -width indent -compact
142 file descriptor number or cwd/root/jail
148 file descriptor flags
150 file descriptor reference count
152 file descriptor offset
156 file path or socket addresses (if available)
159 The following file descriptor types may be displayed:
161 .Bl -tag -width X -compact
179 pseudo-terminal master
184 The following vnode types may be displayed:
186 .Bl -tag -width X -compact
207 The following file descriptor flags may be displayed:
209 .Bl -tag -width X -compact
227 descriptor is a capability
232 flag is specified, the vnode type, reference count, and offset fields will be
233 omitted, and a new capabilities field will be included listing capabilities,
236 present for each capability descriptor.
237 .Ss Signal Disposition Information
238 Display signal pending and disposition for a process:
240 .Bl -tag -width ident -compact
248 process signal disposition details, three symbols
249 .Bl -tag -width X -compact
251 if signal is pending in the global process queue, - otherwise
253 if signal delivery disposition is SIGIGN, - otherwise
255 if signal delivery is to catch it, - otherwise
261 switch is given, the signal numbers are shown instead of signal names.
262 .Ss Thread Signal Information
263 Display signal pending and blocked for a process threads:
265 .Bl -tag -width ident -compact
275 thread signal delivery status, two symbols
276 .Bl -tag -width X -compact
278 if signal is pending for the thread, - otherwise
280 if signal is blocked in the thread signal mask, - if not blocked
286 switch has the same effect as for the
288 switch, the signals numbers are shown instead of signal names.
289 .Ss Kernel Thread Stacks
290 Display kernel thread stacks for a process, allowing further interpretation
291 of thread wait channels.
294 flag is repeated, function offsets, not just function names, are printed.
296 This feature requires
300 to be compiled into the kernel.
302 .Bl -tag -width indent -compact
312 kernel thread call stack
314 .Ss Security Credentials
315 Display process credential information:
317 .Bl -tag -width indent -compact
335 file creation mode mask
342 The following credential flags may be displayed:
344 .Bl -tag -width X -compact
348 .Ss Thread Information
349 Display per-thread information, including process ID, per-thread ID, name,
350 CPU, and execution state:
352 .Bl -tag -width indent -compact
362 current or most recent CPU run on
370 .Ss Virtual Memory Mappings
371 Display process virtual memory mappings, including addresses, mapping
372 meta-data, and mapped object information:

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