.SH DESCRIPTION
|
|
.PP
|
|
\fIPs\fR prints the status of active processes. Normally only the caller's own
|
|
processes are listed in short format (the PID, TTY, TIME and CMD fields as
|
|
explained below). The long listing contains:
|
|
.PP
|
|
ST
|
|
State:
|
|
R: runnable
|
|
W: waiting (on a message)
|
|
S: sleeping (i.e.,suspended on PM or VFS)
|
|
Z: zombie
|
|
T: stopped
|
|
.PP
|
|
UID, PID, PPID, PGRP
|
|
The user, process, parent process and process group ID's.
|
|
.PP
|
|
SZ
|
|
Size of the process in kilobytes.
|
|
.PP
|
|
RECV
|
|
Process/task on which a receiving process is waiting or sleeping.
|
|
.PP
|
|
TTY
|
|
Controlling tty for the process.
|
|
.PP
|
|
TIME
|
|
Process' cumulative (user + system) execution time.
|
|
.PP
|
|
CMD Command line arguments of the process.
|
|
.PP
|
|
.PP
|
|
The \fI/proc\fR file system is used to obtain the process information.
|
|
Terminal names in \fI/dev\fR are used to generate the
|
|
mnemonic names in the TTY column, so \fIps\fR is independent of terminal naming
|
|
conventions.
|
|
.SH NOTES
|
|
The '\-' option prefix is not required.
|
|
For marginal compatibility with System V usage, the hidden option
|
|
.B \-e
|
|
means the same as
|
|
.BR \-ax ,
|
|
and
|
|
.B \-f
|
|
is the same as
|
|
.BR \-l .
