International Code Set Support

Single-byte character code sets are supported.

EXAMPLES

Generate a full listing of all processes currently running on your machine:

ps -ef

To see if a certain process exists on the machine, such as the

cron clock daemon, check the far right

column for the command name,

cron,ortry

ps -f -C cron

WARNINGS

Processes can change while

ps is running. The ps command displays processes at only a snapshot in

time. Data printed for defunct processes is irrelevant.

If two special ﬁles for terminals are located at the same select code, that terminal may be reported with

either name. The user can select processes with that terminal using either name.

Users of

ps must not rely on the exact ﬁeld widths and spacing of its output, as these will vary depending

on the system, the release of HP-UX, and the data to be displayed.

When non-standard options are mixed with standard options, then the behavior may be non-standard.

DEPENDENCIES

HP Process Resource Manager

The -P and -R options require the optional HP Process Resource Manager (PRM) software to be installed

and conﬁgured. See prmconﬁg(1) for a description of how to conﬁgure HP PRM, and prmconf (4) for the

deﬁnition of "process resource group."

If HP PRM is not installed and conﬁgured and

-P or -R is speciﬁed, a warning message is displayed and

(for

-P) hyphens (-) are displayed in the prmid and prmgrp columns.
