RHBA-2011:0193 - Bug Fix Advisory
Synopsis
tcsh bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated tcsh package that fixes various bugs is now available for Red Hat
Enterprise Linux 6.
Description
Tcsh is an enhanced and compatible version of the C shell (csh). It is a command
language interpreter, which can be used as an interactive login shell, as well
as a shell script command processor.
This update fixes the following bugs:
- Previously, running tcsh in verbose mode (that is, by using the "-v" option)
caused the shell to append history to its output on exit. With this update, a
patch has been applied to address this issue, and tcsh now works as expected.
(BZ#658171)
- On a local machine, tcsh set the "REMOTEHOST" environment variable to an empty
string, even though this variable should be only set on remote machines. This
error has been fixed, and "REMOTEHOST" is no longer set on a local machine.
(BZ#669176)
- Previously, when command substitution with backquotes was used, extra fork()
was performed. With this update, only one fork() is performed. (BZ#673556)
All users of tcsh are advised to upgrade to this updated package, which resolves
these issues.
Solution
Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
