Synopsis
Updated grep package speeds UTF-8 searching
Type/Severity
Bug Fix Advisory
Topic
An updated grep package that increases the speed of searching UTF-8 encoded
files is now available.
Description
The grep program is a utility for searching text files.
UTF-8 is a text encoding method for multibyte representations of
characters, and is the default encoding on Red Hat Enterprise Linux.
A deficiency has been identified in grep's search algorithm. The algorithm
was found to be inefficient when searching UTF-8 encoded text. The source
of this inefficiency has been identified and fixed.
All users are advised to upgrade to this updated package, which resolves
this issue.
Solution
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
desired RPMs.
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:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
