(Just sending this out there in case anyone is interested. If you have a better
way, pass it on...)
rpm can provide you with the name and architecture when querying the installed
rpms.
Typically rpm -q filename will only tell you it is installed, but not which
architecture(s).
[root@rac2 /etc]$ rpm -qa glibc
glibc-2.5-81
glibc-2.5-81
To get the ARCH you can use --queryformat
'%{NAME}-%{VERSION}-%{RELEASE}-%{ARCH}\n'
[root@rac2 /etc]$ rpm -q --queryformat '%{NAME}-%{VERSION}-%{RELEASE}
%{ARCH}\n' glibc
glibc-2.5-81 x86_64
glibc-2.5-81 i686
To make this simpler, you can create (or add) an alias to /etc/popt, or ~/.popt:
rpm exec -q rpmq -q --queryformat
'%{NAME}-%{VERSION}-%{RELEASE} %{ARCH}\n'
Take a look at /usr/lib/rpm/rpmopt-{version} to see a horde of aliases that rpm
uses to get an idea what's available.
