It can also display information extracted from a process core file, if the core file is specified as the argument. .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 -libxo Generate output 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. .It Fl b Display binary information for the process. .It Fl c Display command line arguments for the process. .It Fl e Display environment variables for the process. .It Fl f Display file descriptor information for the process. .It Fl i Display signal pending and disposition information for the process. .It Fl j Display signal pending and blocked information for the process's threads. .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. .It Fl l Display resource limits for the process. .It Fl L Display LWP info for the process pertaining to it's signal driven exit. .It Fl r Display resource usage information for the process. .It Fl s Display security credential information for the process. .It Fl S Display the cpuset information for the thread. .It Fl t Display thread information for the process. .It Fl v Display virtual memory mappings for the process. .It Fl x Display ELF auxiliary vector 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 The .Fl C flag requests the printing of additional capability information in the file descriptor view. .Pp The .Fl H flag may be used to request per-thread statistics rather than per-process statistics for some options. For those options, the second field in the table will list the thread ID to which the row of information corresponds. The .Fl H flag is implied for the .Fl S mode. .Pp Information for VM, file descriptor, and cpuset options is available only to the owner of a process or the superuser. A cpuset value displayed as -1 means that the information is either invalid or not available. .Ss Binary Information Display the process ID, command, and path to the process binary: .Pp .Bl -tag -width indent -compact .It PID process ID .It COMM command .It OSREL osreldate for process binary .It PATH path to process binary (if available) .El .Ss Command Line Arguments Display the process ID, command, and command line arguments: .Pp .Bl -tag -width indent -compact .It PID process ID .It COMM command .It ARGS command line arguments (if available) .El .Ss Environment Variables Display the process ID, command, and environment variables: .Pp .Bl -tag -width "ENVIRONMENT" -compact .It PID process ID .It COMM command .It ENVIRONMENT environment variables (if available) .El .Ss File Descriptors Display detailed information about each file descriptor referenced by a process, including the process ID, command, file descriptor number, and per-file descriptor object information, such as object type and file system path. By default, the following information will be printed: .Pp .Bl -tag -width indent -compact .It PID process ID .It COMM command .It FD file descriptor number or cwd/root/jail .It T file descriptor type .It V vnode type .It FLAGS file descriptor flags .It REF file descriptor reference count .It OFFSET file descriptor offset .It PRO network protocol .It NAME file path or socket addresses (if available) .El .Pp The following file descriptor types may be displayed: .Pp .Bl -tag -width X -compact .It c crypto .It e POSIX semaphore .It f fifo .It h shared memory .It k kqueue .It m message queue +.It P +process descriptor .It p pipe .It s socket .It t pseudo-terminal master .It v vnode .El .Pp The following vnode types may be displayed: .Pp .Bl -tag -width X -compact .It - not a vnode .It b block device .It c character device .It d directory .It f fifo .It l symbolic link .It r regular file .It s socket .It x revoked device .El .Pp The following file descriptor flags may be displayed: .Pp .Bl -tag -width X -compact .It r read .It w write .It a append .It s async .It f fsync .It n non-blocking .It d direct I/O .It l lock held .El .Pp If the .Fl C flag is specified, the vnode type, reference count, and offset fields will be omitted, and a new capabilities field will be included listing capabilities, as described in .Xr cap_rights_limit 2 , present for each capability descriptor. .Pp The following network protocols may be displayed (grouped by address family): .Pp .Dv AF_INET , .Dv AF_INET6 .Pp .Bl -tag -width indent -compact .It ICM .Dv IPPROTO_ICMP ; see .Xr icmp 4 . .It IPD .Dv IPPROTO_DIVERT ; see .Xr divert 4 . .It IP? unknown protocol. .It RAW .Dv IPPROTO_RAW ; see .Xr ip 4 . .It SCT .Dv IPPROTO_SCTP ; see .Xr sctp 4 . .It TCP .Dv IPPROTO_TCP ; see .Xr tcp 4 . .It UDP .Dv IPPROTO_UDP ; see .Xr udp 4 . .El .Pp .Dv AF_LOCAL .Pp .Bl -tag -width indent -compact .It UDD .Dv IPPROTO_UDP ; see .Xr udp 4 . .It UDS .Dv IPPROTO_TCP ; see .Xr tcp 4 . .It UD? unknown protocol. .El .Pp .Bl -tag -width indent -compact .It ? unknown address family. .El .Ss Signal Disposition Information Display signal pending and disposition for a process: .Pp .Bl -tag -width indent -compact .It PID process ID .It COMM command .It SIG signal name .It FLAGS process signal disposition details, three symbols .Bl -tag -width X -compact .It P if signal is pending in the global process queue; - otherwise. .It I if signal delivery disposition is .Dv SIG_IGN; - otherwise. .It C if the signal will be caught; - otherwise. .El .El .Pp If .Fl n switch is given, the signal numbers are shown instead of signal names. .Ss Thread Signal Information Display signal pending and blocked for a process's threads: .Pp .Bl -tag -width indent -compact .It PID process ID .It TID thread ID .It COMM command .It SIG signal name .It FLAGS thread signal delivery status, two symbols .Bl -tag -width X -compact .It P if signal is pending for the thread, - otherwise .It B if signal is blocked in the thread signal mask, - if not blocked .El .El .Pp The .Fl n switch has the same effect as for the .Fl i switch: the signal numbers are shown instead of signal names. .Ss Kernel Thread Stacks Display kernel thread stacks for a process, allowing further interpretation of thread wait channels. If the .Fl k flag is repeated, function offsets, not just function names, are printed. .Pp This feature requires .Cd "options STACK" or .Cd "options DDB" to be compiled into the kernel. .Pp .Bl -tag -width indent -compact .It PID process ID .It TID thread ID .It COMM command .It TDNAME thread name .It KSTACK kernel thread call stack .El .Ss Resource Limits Display resource limits for a process: .Pp .Bl -tag -width indent -compact .It PID process ID .It COMM command .It RLIMIT resource limit name .It SOFT soft limit .It HARD hard limit .El .Ss Resource Usage Display resource usage for a process.

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. .Pp .Nm currently supports extracting data only from a live kernel, and not from kernel crash dumps.
