Without options, \fBps\fR prints information about processes that have the same effective user \fBID\fR and the same controlling terminal as the invoker. The output contains only the process \fBID\fR, terminal identifier, cumulative execution time, and the command name. Otherwise, the information that is displayed is controlled by the options. .sp .LP Some options accept lists as arguments. Items in a list can be either separated by commas or else enclosed in quotes and separated by commas or spaces. Values for \fIproclist\fR and \fIgrplist\fR must be numeric. .SH OPTIONS .sp .LP The following options are supported: .sp .ne 2 .na \fB\fB-a\fR\fR .ad .RS 15n Lists information about \fBa\fRll processes most frequently requested: all those except session leaders and processes not associated with a terminal. .RE .sp .ne 2 .na \fB\fB-A\fR\fR .ad .RS 15n Lists information for all processes. Identical to \fB-e\fR, below. .RE .sp .ne 2 .na \fB\fB-c\fR\fR .ad .RS 15n Prints information in a format that reflects scheduler properties as described in \fBpriocntl\fR(1). The \fB-c\fR option affects the output of the \fB-f\fR and \fB-l\fR options, as described below. .RE .sp .ne 2 .na \fB\fB-d\fR\fR .ad .RS 15n Lists information about all processes except session leaders. .RE .sp .ne 2 .na \fB\fB-e\fR\fR .ad .RS 15n Lists information about \fBe\fRvery process now running. .sp When the \fB-e\fRoption is specified, options \fB-z\fR, \fB-t\fR, \fB-u\fR, \fB-U\fR, \fB-g\fR, \fB-G\fR, \fB-p\fR, \fB-g\fR, \fB-s\fR and \fB-a\fR options have no effect. .RE .sp .ne 2 .na \fB\fB-f\fR\fR .ad .RS 15n Generates a \fBf\fRull listing. (See below for significance of columns in a full listing.) .RE .sp .ne 2 .na \fB\fB-g\fR \fIgrplist\fR\fR .ad .RS 15n Lists only process data whose group leader's \fBID\fR number(s) appears in \fIgrplist\fR. (A group leader is a process whose process \fBID\fR number is identical to its process group \fBID\fR number.) .RE .sp .ne 2 .na \fB\fB-G\fR \fIgidlist\fR\fR .ad .RS 15n Lists information for processes whose real group ID numbers are given in \fIgidlist\fR. The \fIgidlist\fR must be a single argument in the form of a blank- or comma-separated list. .RE .sp .ne 2 .na \fB\fB-h\fR \fIlgrplist\fR\fR .ad .RS 15n Lists only the processes homed to the specified \fIlgrplist\fR. Nothing is listed for any invalid group specified in \fIlgrplist\fR. .RE .sp .ne 2 .na \fB\fB-H\fR\fR .ad .RS 15n Prints the home lgroup of the process under an additional column header, LGRP. .RE .sp .ne 2 .na \fB\fB-j\fR\fR .ad .RS 15n Prints session \fBID\fR and process group \fBID\fR. .RE .sp .ne 2 .na \fB\fB-l\fR\fR .ad .RS 15n Generates a \fBl\fRong listing. (See below.) .RE .sp .ne 2 .na \fB\fB-L\fR\fR .ad .RS 15n Prints information about each light weight process (\fIlwp\fR) in each selected process. (See below.) .RE .sp .ne 2 .na \fB\fB-n\fR \fInamelist\fR\fR .ad .RS 15n Specifies the name of an alternative system \fInamelist\fR file in place of the default. This option is accepted for compatibility, but is ignored. .RE .sp .ne 2 .na \fB\fB-o\fR \fIformat\fR\fR .ad .RS 15n Prints information according to the format specification given in \fIformat\fR. This is fully described in \fBDISPLAY FORMATS\fR. Multiple \fB-o\fR options can be specified; the format specification is interpreted as the space-character-separated concatenation of all the \fIformat\fR option-arguments. .RE .sp .ne 2 .na \fB\fB-p\fR \fIproclist\fR\fR .ad .RS 15n Lists only process data whose process \fBID\fR numbers are given in \fIproclist\fR. .RE .sp .ne 2 .na \fB\fB-P\fR\fR .ad .RS 15n Prints the number of the processor to which the process or lwp is bound, if any, under an additional column header, \fBPSR\fR. .RE .sp .ne 2 .na \fB\fB-s\fR \fIsidlist\fR\fR .ad .RS 15n Lists information on all session leaders whose \fBID\fRs appear in \fIsidlist\fR. .RE .sp .ne 2 .na \fB\fB-t\fR \fIterm\fR\fR .ad .RS 15n Lists only process data associated with \fIterm\fR. Terminal identifiers are specified as a device file name, and an identifier. For example, \fBterm/a\fR, or \fBpts/0\fR. .RE .sp .ne 2 .na \fB\fB-u\fR \fIuidlist\fR\fR .ad .RS 15n Lists only process data whose effective user \fBID\fR number or login name is given in \fIuidlist\fR. In the listing, the numerical user \fBID\fR is printed unless you give the \fB-f\fR option, which prints the login name. .RE .sp .ne 2 .na \fB\fB-U\fR \fIuidlist\fR\fR .ad .RS 15n Lists information for processes whose real user \fBID\fR numbers or login names are given in \fIuidlist\fR. The \fIuidlist\fR must be a single argument in the form of a blank- or comma-separated list. .RE .sp .ne 2 .na \fB\fB-W\fR\fR .ad .RS 15n Truncate long names even when \fBps\fR would normally print them in full. A trailing asterisk marks a long name that has been truncated to fit the column. .RE .sp .ne 2 .na \fB\fB-y\fR\fR .ad .RS 15n Under a long listing (\fB-l\fR), omits the obsolete \fBF\fR and \fBADDR\fR columns and includes an \fBRSS\fR column to report the resident set size of the process. Under the \fB-y\fR option, both \fBRSS\fR and \fBSZ\fR (see below) is reported in units of kilobytes instead of pages. .RE .sp .ne 2 .na \fB\fB-z\fR \fIzonelist\fR\fR .ad .RS 15n Lists only processes in the specified zones. Zones can be specified either by name or ID. This option is only useful when executed in the global zone. .RE .sp .ne 2 .na \fB\fB-Z\fR\fR .ad .RS 15n Prints the name of the zone with which the process is associated under an additional column header, \fBZONE\fR. The \fBZONE\fR column width is limited to 8 characters. Use \fBps\fR \fB-eZ\fR for a quick way to see information about every process now running along with the associated zone name. Use .sp .in +2 .nf ps -eo zone,uid,pid,ppid,time,comm,... .fi .in -2 .sp to see zone names wider than 8 characters. .RE .sp .LP Many of the options shown are used to select processes to list. If any are specified, the default list is ignored and \fBps\fR selects the processes represented by the inclusive OR of all the selection-criteria options. .SH DISPLAY FORMATS .sp .LP Under the \fB-f\fR option, \fBps\fR tries to determine the command name and arguments given when the process was created by examining the user block. Failing this, the command name is printed, as it would have appeared without the \fB-f\fR option, in square brackets. .sp .LP The column headings and the meaning of the columns in a \fBps\fR listing are given below; the letters \fBf\fR and \fBl\fR indicate the option (f\fBull\fR or \fBl\fRong, respectively) that causes the corresponding heading to appear; \fBall\fR means that the heading always appears. \fBNote:\fR These two options determine only what information is provided for a process; they do not determine which processes are listed. .sp .ne 2 .na \fB\fBF\fR(l)\fR .ad .RS 14n Flags (hexadecimal and additive) associated with the process. These flags are available for historical purposes; no meaning should be currently ascribed to them. .RE .sp .ne 2 .na \fB\fBS\fR (l)\fR .ad .RS 14n The state of the process: .sp .ne 2 .na \fBO\fR .ad .RS 5n Process is running on a processor. .RE .sp .ne 2 .na \fBS\fR .ad .RS 5n Sleeping: process is waiting for an event to complete. .RE .sp .ne 2 .na \fBR\fR .ad .RS 5n Runnable: process is on run queue. .RE .sp .ne 2 .na \fBT\fR .ad .RS 5n Process is stopped, either by a job control signal or because it is being traced. .RE .sp .ne 2 .na \fBW\fR .ad .RS 5n Waiting: process is waiting for CPU usage to drop to the CPU-caps enforced limits. .RE .sp .ne 2 .na \fBZ\fR .ad .RS 5n Zombie state: process terminated and parent not waiting. .RE .RE .sp .ne 2 .na \fB\fBUID\fR (f,l)\fR .ad .RS 14n The effective user \fBID\fR number of the process (the login name is printed under the \fB-f\fR option). A trailing asterisk marks a long name that has been truncated to fit the column. .RE .sp .ne 2 .na \fB\fBPID\fR(all)\fR .ad .RS 14n The process \fBID\fR of the process (this datum is necessary in order to kill a process). .RE .sp .ne 2 .na \fB\fBPPID\fR(f,l)\fR .ad .RS 14n The process \fBID\fR of the parent process. .RE .sp .ne 2 .na \fB\fBC\fR(f,l)\fR .ad .RS 14n Processor utilization for scheduling (obsolete). Not printed when the \fB-c\fR option is used. .RE .sp .ne 2 .na \fB\fBCLS\fR(f,l)\fR .ad .RS 14n Scheduling class. Printed only when the \fB-c\fR option is used. .RE .sp .ne 2 .na \fB\fBPRI\fR(l)\fR .ad .RS 14n The priority of the process. Without the \fB-c\fR option, higher numbers mean lower priority. With the \fB-c\fR option, higher numbers mean higher priority. .RE .sp .ne 2 .na \fB\fBNI\fR(l)\fR .ad .RS 14n Nice value, used in priority computation. Not printed when the \fB-c\fR option is used. Only processes in the certain scheduling classes have a nice value. .RE .sp .ne 2 .na \fB\fBADDR\fR(l)\fR .ad .RS 14n The memory address of the process. .RE .sp .ne 2 .na \fB\fBSZ\fR(l)\fR .ad .RS 14n The total size of the process in virtual memory, including all mapped files and devices, in pages. See \fBpagesize\fR(1). .RE .sp .ne 2 .na \fB\fBWCHAN\fR(l)\fR .ad .RS 14n The address of an event for which the process is sleeping (if blank, the process is running). .RE .sp .ne 2 .na \fB\fBSTIME\fR(f)\fR .ad .RS 14n The starting time of the process, given in hours, minutes, and seconds. (A process begun more than twenty-four hours before the \fBps\fR inquiry is executed is given in months and days.) .RE .sp .ne 2 .na \fB\fBTTY\fR(all)\fR .ad .RS 14n The controlling terminal for the process (the message, \fB?\fR, is printed when there is no controlling terminal). .RE .sp .ne 2 .na \fB\fBTIME\fR(all)\fR .ad .RS 14n The cumulative execution time for the process. .RE .sp .ne 2 .na \fB\fBLTIME\fR(all)\fR .ad .RS 14n The execution time for the lwp being reported. .RE .sp .ne 2 .na \fB\fBCMD\fR(all)\fR .ad .RS 14n The command name (the full command name and its arguments, up to a limit of 80 characters, are printed under the \fB-f\fR option). .RE .sp .LP The following two additional columns are printed when the \fB-j\fR option is specified: .sp .ne 2 .na \fB\fBPGID\fR\fR .ad .RS 8n The process ID of the process group leader. .RE .sp .ne 2 .na \fB\fBSID\fR\fR .ad .RS 8n The process ID of the session leader. .RE .sp .LP The following two additional columns are printed when the \fB-L\fR option is specified: .sp .ne 2 .na \fB\fBLWP\fR\fR .ad .RS 8n The lwp ID of the lwp being reported. .RE .sp .ne 2 .na \fB\fBNLWP\fR\fR .ad .RS 8n The number of lwps in the process (if \fB-f\fR is also specified). .RE .sp .LP Under the \fB-L\fR option, one line is printed for each lwp in the process and the time-reporting fields \fBSTIME\fR and \fBLTIME\fR show the values for the lwp, not the process. A traditional single-threaded process contains only one lwp. .sp .LP A process that has exited and has a parent, but has not yet been waited for by the parent, is marked \fB<defunct>\fR\&. .SS "\fB-o\fR format" .sp .LP The \fB-o\fR option allows the output format to be specified under user control. .sp .LP The format specification must be a list of names presented as a single argument, blank- or comma-separated. Each variable has a default header. The default header can be overridden by appending an equals sign and the new text of the header. The rest of the characters in the argument is used as the header text. The fields specified are written in the order specified on the command line, and should be arranged in columns in the output. The field widths are selected by the system to be at least as wide as the header text (default or overridden value). If the header text is null, such as \fB-o\fR \fIuser=,\fR the field width is at least as wide as the default header text. Long names are not truncated in this mode. If all header text fields are null, no header line is written. .sp .LP The following names are recognized in the POSIX locale: .sp .ne 2 .na \fB\fBuser\fR\fR .ad .RS 10n The effective user \fBID\fR of the process. This is the textual user \fBID\fR, if it can be obtained and the field width permits, or a decimal representation otherwise. .RE .sp .ne 2 .na \fB\fBruser\fR\fR .ad .RS 10n The real user \fBID\fR of the process. This is the textual user \fBID\fR, if it can be obtained and the field width permits, or a decimal representation otherwise. .RE .sp .ne 2 .na \fB\fBgroup\fR\fR .ad .RS 10n The effective group \fBID\fR of the process.

The implementation might truncate this value to the field width; it is implementation-dependent whether any further truncation occurs. It is unspecified whether the string represented is a version of the argument list as it was passed to the command when it started, or is a version of the arguments as they might have been modified by the application. Applications cannot depend on being able to modify their argument list and having that modification be reflected in the output of \fBps\fR.

The snapshot it gives is true only for a split-second, and it might not be accurate by the time you see it. Some data printed for defunct processes is irrelevant. .sp .LP If no options to select processes are specified, \fBps\fR reports all processes associated with the controlling terminal. If there is no controlling terminal, there is no report other than the header. .sp .LP \fBps\fR \fB-ef\fR or \fBps\fR \fB-o\fR \fBstime\fR might not report the actual start of a tty login session, but rather an earlier time, when a getty was last respawned on the tty line. .sp .LP \fBps\fR is \fBCSI\fR-enabled except for login names (usernames).
