=== RPM multiarch support on 64-bit platforms (x86_64, ppc64) ===
 
'''RPM''' supports parallel installation of multiple architectures of the same package.  A default package listing such as <code>rpm -qa</code> might appear to include duplicate packages, since the architecture is not displayed.  Instead, use the <code>repoquery</code> command, part of the <code>yum-utils</code> package, which displays architecture by default.  To install <code>yum-utils</code>, run the following command:
 
<pre> su -c 'yum install yum-utils'
</pre>
 
To list all packages with their architecture using <code>rpm</code>, run the following command:
 
<pre> rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n"
</pre>
 
You can add this to <code>/etc/rpm/macros</code> (for a system wide setting) or <code>~/.rpmmacros</code> (for a per-user setting).  It changes the default query to list the architecture:
 
<pre> %_query_all_fmt        %%{name}-%%{version}-%%{release}.%%{arch}
</pre>
