+By default, the display includes only processes that have +controlling terminals and are owned by your uid. +The default sort order of controlling terminal and +(among processes with the same controlling terminal) process ID +may be changed using the +.Fl k , Fl m , +or +.Fl r +options. +.Pp +The information displayed for each process +is selected based on a set of keywords (see the +.Fl L , +.Fl O , +and +.Fl o +options). +The default output format includes, for each process, the process' ID, +controlling terminal, CPU time (including both user and system time), +state, and associated command. +.Pp +The options are as follows: +.Bl -tag -width XNXsystemXX +.It Fl A +Display information about all processes. +This is equivalent to +.Fl a Fl x . +.It Fl a +Display information about other users' processes as well as your own. +Note that this does not display information about processes +without controlling terminals. +.It Fl C +Change the way the CPU percentage is calculated by using a +.Dq raw +CPU calculation that ignores +.Dq resident +time (this normally has no effect). +.It Fl c +Do not display full command with arguments, but only the +executable name. +This may be somewhat confusing; for example, all +.Xr sh 1 +scripts will show as +.Dq sh . +.It Fl d +Arrange processes into descendancy order and prefix each command with +indentation text showing sibling and parent/child relationships. +If either of the +.Fl m +and +.Fl r +options are also used, they control how sibling processes are sorted +relative to each other. +.It Fl e +Display the environment as well. +The environment for other +users' processes can only be displayed by the super-user. +.It Fl h +Repeat the information header as often as necessary to guarantee one +header per page of information. +.It Fl j +Print information associated with the following keywords: +.Ar user , pid , ppid , pgid , sess , jobc , state , tt , time , +and +.Ar command . +.It Fl k Ar key +Sort the output using the space or comma separated list of keywords. +Multiple sort keys may be specified, using any of the +.Fl k , Fl m , +or +.Fl r +options. +The default sort order is equivalent to +.Fl k Ar tdev,pid . +.It Fl L +List the set of available keywords. +.It Fl l +Display information associated with the following keywords: +.Ar uid , pid , ppid , cpu , pri , nice , vsz , rss , wchan , state , +.Ar tt , time , +and +.Ar command . +.It Fl M Ar core +Extract values from the specified core file instead of the running system. +.It Fl m +Sort by memory usage. +This is equivalent to +.Fl k Ar vsz . +.It Fl N Ar system +Extract the name list from the specified system instead of the default, +.Dq Pa /netbsd . +Ignored unless +.Fl M +is specified. +.It Fl O Ar fmt +Display information associated with the space or comma separated list +of keywords specified. +The +.Fl O +option does not suppress the default display; +it inserts additional keywords just after the +.Ar pid +keyword in the default display, or after the +.Ar pid +keyword (if any) in a non-default display specified before the +first use of the +.Fl O +flag. +Keywords inserted by multiple +.Fl O +options will be adjacent. +.Pp +An equals sign +.Pq Dq \&= +followed by a customised header string may be appended to a keyword, +as described in more detail under the +.Fl o +option. +.It Fl o Ar fmt +Display information associated with the space or comma separated list +of keywords specified. +Use of the +.Fl o +option suppresses the set of keywords that would be displayed by default, +or appends to the set of keywords specified by other options. +.Pp +An equals sign +.Pq Dq \&= +followed by a customised header string may be appended to a keyword. +This causes the printed header to use the specified string instead of +the default header associated with the keyword. +.Pp +Everything after the first equals sign is part of the customised +header text, and this may include embedded spaces +.Pq Dq " " , +commas +.Pq Dq \&, , +or equals signs +.Pq Dq \&= . +To specify multiple keywords with customised headers, use multiple +.Fl o +or +.Fl O +options. +.Pp +If all the keywords to be displayed have customised headers, +and all the customised headers are entirely empty, +then the header line is not printed at all. +.It Fl p Ar pid +Display information associated with the specified process ID. +.It Fl r +Sort by current CPU usage. +This is equivalent to +.Fl k Ar %cpu . +.It Fl S +Change the way the process time is calculated by summing all exited +children to their parent process. +.It Fl s +Display one line for each LWP, rather than one line for each process, +and display information associated with the following keywords: +.Ar uid , pid , ppid , cpu , lid , nlwp , pri , nice , vsz , rss , +.Ar wchan , lstate , tt , time , +and +.Ar command . +.It Fl T +Display information about processes attached to the device associated +with the standard input. +.It Fl t Ar tty +Display information about processes attached to the specified terminal +device. +Use a question mark +.Pq Dq \&? +for processes not attached to a +terminal device and a minus sign +.Pq Dq - +for processes that have +been revoked from their terminal device. +.It Fl U Ar user +Display processes belonging to the specified user, +given either as a user name or a uid. +.It Fl u +Display information associated with the following keywords: +.Ar user , pid , %cpu , %mem , vsz , rss , tt , state , start , time , +and +.Ar command . +The +.Fl u +option implies the +.Fl r +option. +.It Fl v +Display information associated with the following keywords: +.Ar pid , state , time , sl , re , pagein , vsz , rss , lim , tsiz , +.Ar %cpu , %mem , +and +.Ar command . +The +.Fl v +option implies the +.Fl m +option. +.It Fl W Ar swap +Extract swap information from the specified file instead of the default, +.Dq Pa /dev/drum . +Ignored unless +.Fl M +is specified. +.It Fl w +Use 132 columns to display information instead of the default, which +is your window size. +If the +.Fl w +option is specified more than once, +.Nm +will use as many columns as necessary without regard to your window size. +.It Fl x +Also display information about processes without controlling terminals. +.El +.Pp +A complete list of the available keywords are listed below. +Some of these keywords are further specified as follows: +.Bl -tag -width indent +.It Ar %cpu +The CPU utilization of the process; this is a decaying average over up to +a minute of previous (real) time. +Since the time base over which this is computed varies (since processes may +be very young) it is possible for the sum of all %CPU fields to exceed 100%. +.It Ar %mem +The percentage of real memory used by this process. +.It Ar flags +The

+displayed using the +.Dq %a%p +format. +Otherwise, the start time is displayed using the +.Dq %e%b%y +format. +.It Ar state +The state is given by a sequence of letters, for example, +.Dq RNs . +The first letter indicates the run state of the process: +.Pp +.Bl -tag -width indent -compact +.It D +Marks a process in device or other short term, uninterruptible wait. +.It I +Marks a process that is idle (sleeping interruptibly for longer than about +.Dv MAXSLP +(default 20) seconds). +.It O +Marks a process running on a processor. +.It R +Marks a runnable process, or one that is in the process of creation. +.It S +Marks a process that is sleeping interruptibly for less than about +.Dv MAXSLP +(default 20) seconds. +.It T +Marks a stopped process. +.It U +Marks a suspended process. +.It Z +Marks a dead process that has exited, but not been waited for (a +.Dq zombie ) . +.El +.Pp +Additional characters after these, if any, indicate additional state +information: +.Pp +.Bl -tag -width indent -compact +.It + +The process is in the foreground process group of its control terminal. +.It - +The LWP is detached (can't be waited for). +.It < +The process has raised CPU scheduling priority. +.It a +The process is using scheduler activations (deprecated). +.It E +The process is in the process of exiting. +.It K +The process is a kernel thread or system process. +.It l +The process has multiple LWPs. +.It N +The process is niced (has reduced CPU scheduling priority) (see +.Xr setpriority 2 ) . +.It s +The process is a session leader. +.It V +The process is suspended during a +.Xr vfork 2 . +.It X +The process is being traced or debugged. +.El +.It Ar tt +An abbreviation for the pathname of the controlling terminal, if any. +The abbreviation consists of the two letters following +.Dq Pa /dev/tty +or, for the console, +.Dq co . +This is followed by a +.Dq \&- +if the process can no longer reach that +controlling terminal (i.e., it has been revoked). +.It Ar wchan +The event (an address in the system) on which a process waits. +When printed numerically, the initial part of the address is +trimmed off and the result is printed in hex, for example, 0x80324000 prints +as 324000. +.El +.Pp +When printing using the +.Ar command +keyword, a process that has exited and has a parent that has not yet +waited for the process (in other words, a zombie) is listed as +.Dq Aq defunct , +and a process which is blocked while trying to exit is listed as +.Dq Aq exiting . +.Pp +.Nm +will try to locate the processes' argument vector from the user +area in order to print the command name and arguments. +This method is not reliable because a process is allowed to destroy this +information. +The +.Ar ucomm +(accounting) keyword will always contain the real command name as +contained in the process structure's +.Va p_comm +field. +.Pp +If the command vector cannot be located (usually because it has not +been set, as is the case of system processes and/or kernel threads) +the command name is printed within square brackets. +.Pp +To indicate that the argument vector has been tampered with, +.Nm +will append the real command name to the output within parentheses +if the basename of the first argument in the argument vector +does not match the contents of the real command name. +.Pp +In addition, +.Nm +checks for the following two situations and does not append the +real command name parenthesized: +.Bl -tag -width indent +.It -shellname +The login process traditionally adds a +.Sq - +in front of the shell name to indicate a login shell. +.Nm +will not append parenthesized the command name if it matches with +the name in the first argument of the argument vector, skipping +the leading +.Sq - . +.It daemonname: current-activity +Daemon processes frequently report their current activity by setting +their name to be like +.Dq daemonname: current-activity . +.Nm +will not append parenthesized the command name, if the string preceding the +.Sq \&: +in the first argument of the argument vector matches the command name. +.El +.Sh KEYWORDS +The following is a complete list of the available keywords and their +meanings. +Several of
