HP-UX Reference (11i v2 04/09) - 1 User Commands N-Z (vol 2)

ps(1) ps(1)

WARNINGS

Things can change while ps is running; the picture it gives is only a snapshot in time. Some 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 depend-

ing 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.
