1.77.3. RHBA-2011:0513: ksh bug fix update

An updated ksh package that fixes one bug is now available for Red Hat Enterprise Linux 5.

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

This update fixes the following bug:

* When running a script, the previous version of ksh could incorrectly consider the "eval" command to be the last in the script, and did not run it in a separate process. Consequent to this, using "eval" or executing commands from another file (that is, by using the "." built-in command) may have prevented ksh from executing any subsequent commands. With this update, the underlying source code has been adapted to determine whether a script contains other commands, and perform the selected action in a separate process if it does. As a result, ksh now executes all commands in a script as expected. (BZ#702364)

All users of ksh are advised to upgrade to this updated package, which fixes this bug.
