8.8 Freshening a Package

From time to time, Red Hat issues updated packages that correct functional or security-related problems with released packages. You can use Red Hat Network, described later in this chapter in Section 8.10, to obtain and install updated packages. However, if you prefer, you can download updated packages via FTP and install them using the rpm command. Red Hat makes updated packages available on the public FTP servers ftp.redhat.com and updates.redhat.com.

To install an updated package, use the -F flag, which stands for freshen. For instance, to install a updated version of the gv package, issue the command:

rpm -Fvh gv-3.5.8-19.i386.rpm

By specifying -F rather than -U, you instruct RPM to install the updated package only if an earlier version of the package is already present. This lets you use wildcards to specify entire sets of updated packages:

rpm -Fvh *.rpm

This command will not install packages that aren't already installed. But, it will install updated versions of any existing packages.
