Bug Fix Advisory
Updated "at" packages that address the improper selection of the shell used
for running jobs are now available. A man page containing incorrect
information has also been revised.
The "at" and "batch" utilities are used to run a specified job at the
The "at" and "batch" man page claim (as does a warning message when these
utilities are run) that the job will be run using the first shell available
from the following list:
- The value of the SHELL environment variable
- The user's login shell
However, jobs are actually always run using /bin/sh.
This update changes the behavior to use SHELL if it is defined, otherwise
/bin/sh. It works for Bourne-style shells (bash, sh, zsh, ksh, and ash),
but C-style shells (csh and tcsh) are unsupported due to their use of a
different syntax for setting environment variables.
In addition, the package's man page has been updated to reflect the
corrected behavior, and the warning message has been eliminated.
Users of "at" or "batch" that require the use of a shell other than /bin/sh
should update to these erratum packages, which resolve this issue.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
