12.5. Useful yum Variables
The following is a list of variables you can use for both
yum commands and
yum configuration files (i.e.
/etc/yum.conf and
.repo files).
-
$releasever
-
This is replaced with the package's version, as listed in
distroverpkg. This defaults to the version of the redhat-release package.
-
$arch
-
This is replaced with your system's architecture, as listed by
os.uname() in Python.
-
$basearch
-
This is replaced with your base architecture. For example, if
$arch=i686 then $basearch=i386.
-
$YUM0-9
-
This is replaced with the value of the shell environment variable
of the same name. If the shell environment variable does not exist, then
the configuration file variable will not be replaced.
