RHEA-2010:0694 - Product Enhancement Advisory

Topic

An updated Ksh package that brings enhanced ulimit support is now available for
Red Hat Enterprise Linux 5.

Description

KornShell is a shell programming language which is also compatible with "sh",
the original Bourne Shell. KSH-93 is the most recent version of the KornShell by
David Korn of AT&TBell Laboratories.

This updated ksh package adds the following enhancement:

• previously the ksh ulimit builtin lacked support for RLIMIT_RTPRIO and

RLIMIT_NICE. This did not allow full usage of ksh by script writers. With this
update, the ksh package adds the ability to read and set both RLIMIT_RTPRIO and
RLIMIT_NICE with the ulimit builtin. (BZ#626790)

KornShell users, especially those who require RLIMIT_RTPRIO or RLIMIT_NICE, are
advised to upgrade to this updated package, which adds this enhancement.
