RHBA-2012:0937 - zsh bug fix and enhancement update

Synopsis

zsh bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated zsh packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The zsh shell is a command interpreter which can be used as an interactive login shell and as a shell script command processor. Zsh resembles the ksh shell (the Korn shell), but includes many enhancements. Zsh supports command line editing, built-in spelling correction, programmable command completion, shell functions (with autoloading), a history mechanism, and more.

This update fixes the following bug:

  • Prior to this update, the zsh shell attempted to execute mathematical expressions in the "-n" option when running in ksh mode. As a consequence, zsh emitted errors when running a syntax only check. This update modifies the source code so that mathematical expressions are now handled like any other command when using the "-n" option. (BZ#657300)

This update also adds the following enhancement:

  • Prior to this update, a script whose location was listed in "$PATH" could not be run with the zsh shell. With this update, users can call a script from "$PATH" with the "-o pathscript" option to search path when zsh is invoked directly. (BZ#612685)

All users are advised to upgrade to these updated packages, which fix this bug and add this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
