RHBA-2009:1494 - Bug Fix Advisory

Topic

An updated tcsh package that fixes a bug is now available.

Description

Tcsh is an enhanced and compatible version of the C shell (csh). Tcsh is a
command language interpreter, which can be used as an interactive login
shell, as well as a shell script command processor.

This updated tcsh package fixes the following bug:

• when using the tcsh shell, running a command containing glob characters

(such as "echo FAIL *", for example) within a directory in which automount
mounted other directories (such as for NIS) based on a wildcard entry in
the automount map file caused the service to attempt to mount those
directories and fail, thereby increasing network traffic and system load.
This update provides a fix to tcsh glob-handling so that using globbing
characters as in the above example no longer triggers automount, thus
resolving the issue. (BZ#526459)

All users of tcsh are advised to upgrade to this updated package, which
resolves this issue.
