57processes that have controlling terminals. 58If the 59.Fl x 60options is specified, 61.Nm 62will also display processes that do not have controlling terminals. 63.Pp 64A different set of processes can be selected for display by using any 65combination of the 66.Fl a , G , J , p , T , t , 67and 68.Fl U 69options. 70If more than one of these options are given, then 71.Nm 72will select all processes which are matched by at least one of the 73given options. 74.Pp 75For the processes which have been selected for display, 76.Nm 77will usually display one line per process. 78The 79.Fl H 80option may result in multiple output lines (one line per thread) for 81some processes. 82By default all of these output lines are sorted first by controlling 83terminal, then by process ID. 84The 85.Fl m , r , u , 86and 87.Fl v 88options will change the sort order. 89If more than one sorting option was given, then the selected processes 90will be sorted by the last sorting option which was specified. 91.Pp 92For the processes which have been selected for display, the information 93to display is selected based on a set of keywords (see the 94.Fl L , O , 95and 96.Fl o 97options). 98The default output format includes, for each process, the process' ID, 99controlling terminal, state, CPU time (including both user and system time) 100and associated command. 101.Pp 102The options are as follows: 103.Bl -tag -width indent 104.It Fl a 105Display information about other users' processes as well as your own. 106If the 107.Va security.bsd.see_other_uids 108sysctl is set to zero, this option is honored only if the UID of the user is 0. 109.It Fl c 110Change the 111.Dq command 112column output to just contain the executable name, 113rather than the full command line. 114.It Fl C 115Change the way the CPU percentage is calculated by using a 116.Dq raw 117CPU calculation that ignores 118.Dq resident 119time (this normally has 120no effect). 121.It Fl d 122Arrange processes into descendancy order and prefix each command with 123indentation text showing sibling and parent/child relationships. 124If either of the 125.Fl m 126and 127.Fl r 128options are also used, they control how sibling processes are sorted 129relative to each other. 130Note that this option has no effect if the 131.Dq command 132column is not the last column displayed. 133.It Fl e 134Display the environment as well. 135.It Fl f 136Show commandline and environment information about swapped out processes. 137This option is honored only if the UID of the user is 0. 138.It Fl G 139Display information about processes which are running with the specified 140real group IDs. 141.It Fl H 142Show all of the 143.Em kernel visible 144threads associated with each process. 145Depending on the threading package that 146is in use, this may show only the process, only the kernel scheduled entities, 147or all of the process threads. 148.It Fl h 149Repeat the information header as often as necessary to guarantee one 150header per page of information. 151.It Fl j 152Print information associated with the following keywords: 153.Cm user , pid , ppid , pgid , sid , jobc , state , tt , time , 154and 155.Cm command . 156.It Fl J 157Display information about processes which match the specified jail IDs. 158This may be either the 159.Cm jid 160or 161.Cm name 162of the jail. 163Use 164.Fl J 165.Sy 0 166to display only host processes. 167This flag implies 168.Fl x 169by default. 170.It Fl L 171List the set of keywords available for the 172.Fl O 173and 174.Fl o 175options. 176.It Fl l 177Display information associated with the following keywords: 178.Cm uid , pid , ppid , cpu , pri , nice , vsz , rss , mwchan , state , 179.Cm tt , time , 180and 181.Cm command . 182.It Fl M 183Extract values associated with the name list from the specified core 184instead of the currently running system. 185.It Fl m 186Sort by memory usage, instead of the combination of controlling 187terminal and process ID. 188.It Fl N 189Extract the name list from the specified system instead of the default, 190which is the kernel image the system has booted from. 191.It Fl O 192Add the information associated with the space or comma separated list 193of keywords specified, after the process ID, 194in the default information 195display. 196Keywords may be appended with an equals 197.Pq Ql = 198sign and a string. 199This causes the printed header to use the specified string instead of 200the standard header. 201.It Fl o 202Display information associated with the space or comma separated 203list of keywords specified. 204The last keyword in the list may be appended with an equals 205.Pq Ql = 206sign and a string that spans the rest of the argument, and can contain 207space and comma characters. 208This causes the printed header to use the specified string instead of 209the standard header. 210Multiple keywords may also be given in the form of more than one 211.Fl o 212option. 213So the header texts for multiple keywords can be changed. 214If all keywords have empty header texts, no header line is written. 215.It Fl p 216Display information about processes which match the specified process IDs. 217.It Fl r 218Sort by current CPU usage, instead of the combination of controlling 219terminal and process ID. 220.It Fl S 221Change the way the process times, namely cputime, systime, and usertime, 222are calculated by summing all exited children to their parent process. 223.It Fl T 224Display information about processes attached to the device associated 225with the standard input. 226.It Fl t 227Display information about processes attached to the specified terminal 228devices. 229Full pathnames, as well as abbreviations (see explanation of the 230.Cm tt 231keyword) can be specified. 232.It Fl U 233Display the processes belonging to the specified usernames. 234.It Fl u 235Display information associated with the following keywords: 236.Cm user , pid , %cpu , %mem , vsz , rss , tt , state , start , time , 237and 238.Cm command . 239The 240.Fl u 241option implies the 242.Fl r 243option. 244.It Fl v 245Display information associated with the following keywords: 246.Cm pid , state , time , sl , re , pagein , vsz , rss , lim , tsiz , 247.Cm %cpu , %mem , 248and 249.Cm command . 250The 251.Fl v 252option implies the 253.Fl m 254option. 255.It Fl w 256Use 132 columns to display information, instead of the default which 257is your window size. 258If the 259.Fl w 260option is specified more than once, 261.Nm 262will use as many columns as necessary without regard for your window size. 263Note that this option has no effect if the 264.Dq command 265column is not the last column displayed. 266.It Fl X 267When displaying processes matched by other options, skip any processes 268which do not have a controlling terminal. 269This is the default behaviour. 270.It Fl x 271When displaying processes matched by other options, include processes 272which do not have a controlling terminal. 273This is the opposite of the 274.Fl X 275option. 276If both 277.Fl X 278and 279.Fl x 280are specified in the same command, then 281.Nm 282will use the one which was specified last. 283.It Fl Z 284Add 285.Xr mac 4 286label to the list of keywords for which 287.Nm 288will display information. 289.El 290.Pp 291A complete list of the available keywords are listed below. 292Some of these keywords are further specified as follows: 293.Bl -tag -width lockname 294.It Cm %cpu 295The CPU utilization of the process; this is a decaying average over up to 296a minute of previous (real) time. 297Since the time base over which this is computed varies (since processes may 298be very young) it is possible for the sum of all 299.Cm %cpu 300fields to exceed 100%. 301.It Cm %mem 302The percentage of real memory used by this process. 303.It Cm class 304Login class associated with the process. 305.It Cm flags 306The flags associated with the process as in

lim 354The soft limit on memory used, specified via a call to 355.Xr setrlimit 2 . 356.It Cm lstart 357The exact time the command started, using the 358.Ql %c 359format described in 360.Xr strftime 3 . 361.It Cm lockname 362The name of the lock that the process is currently blocked on. 363If the name is invalid or unknown, then 364.Dq ???\& 365is displayed. 366.It Cm logname 367The login name associated with the session the process is in (see 368.Xr getlogin 2 ) . 369.It Cm mwchan 370The event name if the process is blocked normally, or the lock name if 371the process is blocked on a lock. 372See the wchan and lockname keywords 373for details. 374.It Cm nice 375The process scheduling increment (see 376.Xr setpriority 2 ) . 377.It Cm rss 378the real memory (resident set) size of the process (in 1024 byte units). 379.It Cm start 380The time the command started. 381If the command started less than 24 hours ago, the start time is 382displayed using the 383.Dq Li %l:ps.1p 384format described in 385.Xr strftime 3 . 386If the command started less than 7 days ago, the start time is 387displayed using the 388.Dq Li %a6.15p 389format. 390Otherwise, the start time is displayed using the 391.Dq Li %e%b%y 392format. 393.It Cm state 394The state is given by a sequence of characters, for example, 395.Dq Li RWNA . 396The first character indicates the run state of the process: 397.Pp 398.Bl -tag -width indent -compact 399.It Li D 400Marks a process in disk (or other short term, uninterruptible) wait. 401.It Li I 402Marks a process that is idle (sleeping for longer than about 20 seconds). 403.It Li L 404Marks a process that is waiting to acquire a lock. 405.It Li R 406Marks a runnable process. 407.It Li S 408Marks a process that is sleeping for less than about 20 seconds. 409.It Li T 410Marks a stopped process. 411.It Li W 412Marks an idle interrupt thread. 413.It Li Z 414Marks a dead process (a 415.Dq zombie ) . 416.El 417.Pp 418Additional characters after these, if any, indicate additional state 419information: 420.Pp 421.Bl -tag -width indent -compact 422.It Li + 423The process is in the foreground process group of its control terminal. 424.It Li < 425The process has raised CPU scheduling priority. 426.It Li E 427The process is trying to exit. 428.It Li J 429Marks a process which is in 430.Xr jail 2 . 431The hostname of the prison can be found in 432.Pa /proc/ Ns Ao Ar pid Ac Ns Pa /status . 433.It Li L 434The process has pages locked in core (for example, for raw 435.Tn I/O ) . 436.It Li N 437The process has reduced CPU scheduling priority (see 438.Xr setpriority 2 ) . 439.It Li s 440The process is a session leader. 441.It Li V 442The process' parent is suspended during a 443.Xr vfork 2 , 444waiting for the process to exec or exit. 445.It Li W 446The process is swapped out. 447.It Li X 448The process is being traced or debugged. 449.El 450.It Cm tt 451An abbreviation for the pathname of the controlling terminal, if any. 452The abbreviation consists of the three letters following 453.Pa /dev/tty , 454or, for pseudo-terminals, the corresponding entry in 455.Pa /dev/pts . 456This is followed by a 457.Ql - 458if the process can no longer reach that 459controlling terminal (i.e., it has been revoked). 460A 461.Ql - 462without a preceding two letter abbreviation or pseudo-terminal device number 463indicates a process which never had a controlling terminal. 464The full pathname of the controlling terminal is available via the 465.Cm tty 466keyword. 467.It Cm wchan 468The event (an address in the system) on which a process waits. 469When printed numerically, the initial part of the address is 470trimmed off and the result is printed in hex, for example, 0x80324000 prints 471as 324000. 472.El 473.Pp 474When printing using the command keyword, a process that has exited and 475has a parent that has not yet waited for the process (in other words, a zombie) 476is listed as 477.Dq Li <defunct> , 478and a process which is blocked while trying 479to exit is listed as 480.Dq Li <exiting> . 481If the arguments cannot be located (usually because it has not been set, as is 482the case of system processes and/or kernel threads) the command name is printed 483within square brackets. 484The 485.Nm 486utility first tries to obtain the arguments cached by the kernel (if they were 487shorter than the value of the 488.Va kern.ps_arg_cache_limit 489sysctl). 490The process can change the arguments shown with 491.Xr setproctitle 3 . 492Otherwise, 493.Nm 494makes an educated guess as to the file name and arguments given when the 495process was created by examining memory or the swap area. 496The method is inherently somewhat unreliable and in any event a process 497is entitled to destroy this information. 498The ucomm (accounting) keyword can, however, be depended on. 499If the arguments are unavailable or do not agree with the ucomm keyword, 500the value for the ucomm keyword is appended to the arguments in parentheses. 501.Sh KEYWORDS 502The following is a complete list of the available keywords and their 503meanings. 504Several of them have aliases (keywords which are synonyms).

741.Sh STANDARDS 742For historical reasons, the 743.Nm 744utility under 745.Fx 746supports a different set of options from what is described by 747.St -p1003.2 , 748and what is supported on 749.No

760process, the information it displays can never be exact. 761.Pp 762The 763.Nm 764utility does not correctly display argument lists containing multibyte 765characters. 766
