Synopsis
ksh bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated ksh package that fixes two bugs is now available.
Description
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 updated ksh package includes fixes for the following bugs:
- when a ksh script included multibyte characters, ksh's script parser then
failed to parse the script and printed a "syntax error" message. This
updated package corrects this error: ksh's script parser now correctly
handles multibyte characters and no error is returned when they are found.
(BZ#543447)
- the ksh shell uses a special variable, "$!", which contains the process
ID (pid) of the last background job or background function. However, the $!
variable did not contain the correct pid when it was called within a ksh
function (defined with the "function" syntax). With this update,
referencing the $! special variable works as expected and the correct
process ID of the last background job or function is returned, even when it
is referenced from within a ksh script function. (BZ#544974)
All KornShell users are advised to upgrade to this updated package, which
resolves these issues.
