43 utility displays detailed information about the processes identified by the
47 flag is used, all processes.
49 By default, basic process statistics are printed; one of the following
50 options may be specified in order to select more detailed process information
52 .Bl -tag -width indent
54 Display binary information for the process.
56 Display command line arguments for the process.
58 Display file descriptor information for the process.
60 Display the stacks of kernel threads in the process, excluding stacks of
61 threads currently running on a CPU and threads with stacks swapped to disk.
62 If the flag is repeated, function offsets as well as function names are
65 Display security credential information for the process.
67 Display thread information for the process.
69 Display virtual memory mappings for the process.
72 All options generate output in the format of a table, the first field of
73 which is the process ID to which the row of information corresponds.
76 flag may be used to suppress table headers.
80 flag may be used to specify a wait interval at which to repeat the printing
81 of the requested process information.
84 flag is not specified, the output will not repeat.
86 Some information, such as VM and file descriptor information, is available
87 only to the owner of a process or the superuser.
88 .Ss Binary Information
89 Display the process ID, command, and path to the process binary:
91 .Bl -tag -width indent -compact
97 path to process binary (if available)
99 .Ss Command Line Arguments
100 Display the process ID, command, and command line arguments:
102 .Bl -tag -width indent -compact
108 command line arguments (if available)
111 Display detailed information about each file descriptor referenced by a
112 process, including the process ID, command, file descriptor number, and
113 per-file descriptor object information, such as object type and file system
116 .Bl -tag -width indent -compact
122 file descriptor number or cwd/root/jail
128 file descriptor flags
130 file descriptor reference count
132 file descriptor offset
136 file path or socket addresses (if available)
139 The following file descriptor types may be displayed:
141 .Bl -tag -width X -compact
159 pseudo-terminal master
164 The following vnode types may be displayed:
166 .Bl -tag -width X -compact
187 The following file descriptor flags may be displayed:
189 .Bl -tag -width X -compact
207 .Ss Kernel Thread Stacks
208 Display kernel thread stacks for a process, allowing further interpretation
209 of thread wait channels.
212 flag is repeated, function offsets, not just function names, are printed.
214 This feature requires
218 to be compiled into the kernel.
220 .Bl -tag -width indent -compact
230 kernel thread call stack
232 .Ss Security Credentials
233 Display process credential information:
235 .Bl -tag -width indent -compact
255 .Ss Thread Information
256 Display per-thread information, including process ID, per-thread ID, name,
257 CPU, and execution state:
259 .Bl -tag -width indent -compact
269 current or most recent CPU run on
277 .Ss Virtual Memory Mappings
278 Display process virtual memory mappings, including addresses, mapping
279 meta-data, and mapped object information:
281 .Bl -tag -width indent -compact
285 starting address of mapping
287 ending address of mapping
293 private resident pages
304 The following protection flags may be displayed:
306 .Bl -tag -width X -compact
315 The following VM object types may be displayed:
317 .Bl -tag -width XX -compact
334 The following mapping flags may be displayed:
336 .Bl -tag -width X -compact

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