|
|---|
| 26 | .PP
|
|---|
| 27 | \fIPs\fR prints the status of active processes. Normally only the caller's own
|
|---|
| 28 | processes are listed in short format (the PID, TTY, TIME and CMD fields as
|
|---|
| 29 | explained below). The long listing contains:
|

|

| 45 | S: sleeping (i.e.,suspended on MM or FS)
|

| 46 | Z: zombie
|

| 47 | T: stopped
|
|---|
| 48 | .PP
|

| 49 | UID, PID, PPID, PGRP
|

| 50 | The user, process, parent process and process group ID's.
|
|---|
| 51 | .PP
|
|---|
| 52 | SZ
|
|---|
| 53 | Size of the process in kilobytes.
|
|---|
| 54 | .PP
|
|---|
| 55 | RECV
|
|---|
| 56 | Process/task on which a receiving process is waiting or sleeping.
|
|---|
| 57 | .PP
|
|---|
| 58 | TTY
|
|---|
| 59 | Controlling tty for the process.
|
|---|
| 60 | .PP
|
|---|
| 61 | TIME
|
|---|

|
|---|
| 66 | .PP
|
|---|
| 67 | The files \fI/dev/{mem,kmem}\fR are used to read the system tables and command
|
|---|
| 68 | line arguments from. Terminal names in \fI/dev\fR are used to generate the
|
|---|
| 69 | mnemonic names in the TTY column, so \fIps\fR is independent of terminal naming
|
|---|
| 70 | conventions.
|
|---|
| 71 | .SH NOTES
|
|---|
| 72 | The '\-' option prefix is not required.
|
|---|
| 73 | For marginal compatibility with System V usage, the hidden option
|
|---|
| 74 | .B \-e
|
|---|
| 75 | means the same as
|
|---|
| 76 | .BR \-ax ,
|
|---|
| 77 | and
|
|---|
| 78 | .B \-f
|
|---|
| 79 | is the same as
|
|---|
| 80 | .BR \-l .
